Cybersecurity: Crash Course Computer Science #31
Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe. Check out Computerphile’s wonderful video on how to choose a password! https://www.youtube.com/watch?v=3NjQ9b3pgIg Pre-order our limited edition Crash Course: Computer Science Floppy Disk Coasters here! https://store.dftba.com/products/computer-science-coasters Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Want to know more about Carrie Anne? https://about.me/carrieannephilbin The Latest from PBS Digital Studios: https://www.youtube.com/playlist?list=PL1mtdjDVOoOqJzeaJAV15Tq0tZ1vKj7ZV Want to find Crash Course elsewhere on the internet?

What is FINANCIAL CRYPTOGRAPHY? What does FINANCIAL CRYPTOGRAPHY mean? FINANCIAL CRYPTOGRAPHY meaning - FINANCIAL CRYPTOGRAPHY definition - FINANCIAL CRYPTOGRAPHY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Financial cryptography (FC) is the use of cryptography in applications in which financial loss could result from subversion of the message system. Financial cryptography is distinguished from traditional cryptography in that for most of recorded history, cryptography has been used almost entirely for military and diplomatic purposes. Financial cryptography includes the mechanisms and algorithms necessary for the protection of financial transfers, in addition to the creation of new forms of money. Proof of work and various auction protocols fall under the umbrella of Financial Cryptography. Hashcash is being used to limit spam. Financial cryptography has been seen to have a very broad scope of application. Ian Grigg sees financial cryptography in seven layers, being the combination of seven distinct disciplines: cryptography, software engineering, rights, accounting, governance, value, and financial applications. Business failures can often be traced to the absence of one or more of these disciplines, or to poor application of them. This views Financial Cryptography as an appropriately cross-discipline subject. Indeed, inevitably so, given that finance and cryptography are each built upon multiple disciplines. Cryptographers think of the field as originating in the work of Dr David Chaum who invented the blinded signature. This special form of a cryptographic signature permitted a virtual coin to be signed without the signer seeing the actual coin, and permitted a form of digital token money that offered untraceability. This form is sometimes known as Digital currency. A system that was widely used during the 1970s-1990s and previously developed cryptographic mechanism is the Data Encryption Standard, which was used primarily for the protection of electronic funds transfers. However, it was the work of David Chaum that excited the cryptography community about the potential of encrypted messages as actual financial instruments. As part of a business model, Financial Cryptography followed the guide of cryptography and only the simplest ideas were adopted. Account money systems protected by SSL such as PayPal and e-gold were relatively successful, but more innovative mechanisms, including blinded token money, were not. Financial cryptography is to some extent organized around the annual meeting of the International Financial Cryptography Association, which is held each year in a different location.

How Much do Engineers and Scientists Make? Salary and Employment Statistics
Two common statistics that are helpful to know about any college major are: how much money you can expect to make, and the amount of job opportunities. Here I outline the statistics for many of the most majors and careers when it comes to engineering, math and science. One thing to note is that science majors very often need additional education. Even in the video there are statistics that don't directly say a master's or PhD is required, however, you'll find many of the people in those jobs have one. Engineering jobs on the other hand often don't require anything past a bachelor's degree. Remember that these statistics are just averages and are not a guarantee of what you'll make. Also note these are NOT starting salaries but rather averages over all people in the fields. *************************************** For information on math, science, and engineering majors, check us out at https://majorprep.com *************************************** ►Patreon: https://patreon.com/majorprep ►PayPal: https://www.paypal.me/majorprep ►Facebook: https://facebook.com/majorprep

Blockchain: Distributed Trust - Bart Preneel
The Bitcoin ecosystem had a bumpy start, but driven in part by the demand created by the Silk Road and perhaps the Cyprus crisis, the impact grew quickly: the total value of bitcoins rose to several billion US$ in the first two years (currently it is around US$ 14 billion), hundreds of alternative cryptocurrencies (altcoins) were created and large mining entities were established, mostly in China. The ideas behind Bitcoin have opened up new approaches to cryptocurrencies, but also to distributed consensus, distributed naming, secure timestamping and commitment. One of the aspects that have drawn the most interest is the smart contract (that is, cryptographically enforceable agreements) on top of the Bitcoin ecosystem (or on other systems such as Ethereum). Even if some observers predict that the Bitcoin ecosystem will disappear or become irrelevant, the core ideas have already made a major impact. Unlike any other payment system or cryptocurrency created before, Bitcoin allows for fully decentralized generation of currency and fully decentralized verification of transactions. The core idea is the blockchain, a public ledger that registers all transactions under the form of a hash chain; the blockchain describes the state of the system, that is, it specifies who owns which amount. Transactions themselves are validated based on a scripting language, which creates some flexibility. In a distributed system, a central problem is how to achieve consensus (e.g., how to deal with double-spending transactions). Transactions are broadcast over a low-latency peer-to-peer network that offers some robustness against censoring or sabotage. This approach allows the Bitcoin ecosystem to achieve distributed consensus in a practical way assuming that players are rational (something which is known to be unachievable without additional assumptions such as rationality) albeit at the cost of a major computational effort in terms of mining. While the financial industry is less interested in the anarchistic aspects of the Bitcoin ecosystem (the governance model and the uncontrolled money supply), the distributed consensus idea is very appealing and is believed to have a very high business potential for a large number of financial transactions and interactions. In 2015, about US$ 1 billion was invested in venture capital in the area of blockchain and cryptocurrencies and the Aite Group predicted in 2016 that blockchain market could be worth as much as US$ 400 million in annual business by 2019. The idea of a public ledger for timestamping and registering documents using hash chains is more than 25 years old, as witnessed by the efforts of Surety Technologies in the early 1990 and the ISO standardization in this area in the mid 1990s –- but these earlier approaches did use a central authority to register all transactions. Bitcoin has inspired many actors to revisit those ideas by `taming’ the Bitcoin ecosystem into a private or permissioned ledger, where only a few selected actors have control over new currencies or verification of transactions (to get rid of distributed control) and where access to the ledger can be restricted (to get rid of full transparency). Some of the notable developments in this context are the open source initiative of IBM that is called Hyperledger and Intel's experimental Sawtooth Lake architecture. Professor Bart Preneel of KU Leuven heads the imec-COSIC (COmputer Security and Industrial Cryptography) research group. His main research areas are information security and privacy with a focus on cryptographic algorithms and protocols and efficient and secure implementations. He undertakes industrial consulting for major players in the finance, telco and hardware industry and has co-designed the Belgian eID and e-voting scheme. He is active in international standardization . Professor Preneel has served as Director, (1997-present), Vice President (2002-2007) and President (2008-2013) of the International Association for Cryptologic Research (IACR) and is co-founder and chairman of LSEC vzw (Leuven Security Excellence Consortium). He is a fellow of the IACR, a member of the Permanent Stakeholders group of ENISA (European Network and Information Security Agency) and of the Academia Europaea. He has testified for the European and Belgian parliament. He has been invited speaker at more than 150 conferences and schools in 40 countries. In 2014 he received the RSA Award for Excellence in the Field of Mathematics.

Verifiable Functional Encryption
In light of security challenges that have emerged in a world with complex networks and cloud computing, the notion of functional encryption has recently emerged. In this work, we show that in several applications of functional encryption (even those cited in the earliest works on functional encryption), the formal notion of functional encryption is actually not sufficient to guarantee security. This is essentially because the case of a malicious authority and/or encryptor is not considered. To address this concern, we put forth the concept of verifiable functional encryption, which captures the basic requirement of output correctness: even if the ciphertext is maliciously generated (and even if the setup and key generation is malicious), the decryptor is still guaranteed a meaningful notion of correctness which we show is crucial in several applications. We give a general compiler from any functional encryption scheme into a verifiable functional encryption scheme with the only additional assumption being the Decision Linear Assumption over Bilinear Groups (DLIN). We also give a generic compiler in the secret-key setting for functional encryption which maintains both message privacy and function privacy. Our positive results are general and also apply to other simpler settings such as Identity-Based Encryption, Attribute-Based Encryption and Predicate Encryption. We also give an application of verifiable functional encryption to the recently introduced primitive of functional commitments. Finally, in the context of indistinguishability obfuscation, there is a fundamental question of whether the correct program was obfuscated. In particular, the recipient of the obfuscated program needs a guarantee that the program indeed does what it was intended to do. This question turns out to be closely related to verifiable functional encryption. We initiate the study of verifiable obfuscation with a formal definition and construction of verifiable indistinguishability obfuscation. This is based on joint work with Vipul Goyal, Aayush Jain and Amit Sahai.

Sofia Crypto Meetup #23 - Smart Contract Security & ICO Valuation Models
2017 was amazing! We witnessed an explosion of interest in the field of blockchain technology and cryptocurrencies. Everyone is a cryptotrader now, even taxi-drivers and housewives. Is this good or bad? It is the only way forward. The cryptocurrency revolution is just starting and the main force behind it currently is greed. Nonetheless, with so much money being invested into research of decentralized governance models and cryptography, much good will come out of it all. We are 100% confident. Remember that: “Nothing great has ever been accomplished without irrational exuberance.” We believe that two of the most important topics of 2018, apart from regulation and blockchain scalability will be blockchain/smart contract security and investments in cryptocurrency and tokens. We are thrilled to announce that we have found just the right speakers to address these hot topics. Here is the agenda: 19:10 – 19:20 Monthly Highlights – Jan 2018, Ivo Vasilev, co-founder Sofia Crypto Meetup 19:15 – 19:40 Automated Formal Verification of Ethereum Smart Contracts Petar Tsankov, ChainSecurity | Scientific Researcher at Software Reliability Lab, ETH Zurich 19:40 – 20:10 Pre- and Post-ICO Valuation Metrics and Techniques Ana-Maria Yanakieva, Blockchain Analyst for LAUNCHub Ventures | BSc Economics at City, University of London 20:10 – END Q&A and Discussions Free beers and wine by æternity blockchain & the BitHope Foundation. Professional video recording by EDIT.bg. The venue – kindly provided by the great people at Betahaus Sofia. See you there! More information about the guest speakers: Petar Tsankov Petar will present Securify (https://securify.ch/), the first push-button security auditing tool for Ethereum smart contracts that is fully automated, easily extensible to new security vulnerabilities, and provides strong security guarantees. The core technical idea behind Securify is to soundly extract deep semantic information from the smart contract using automated abstract reasoning. This information is then used to ensure the absence of critical security vulnerabilities, such as reentrant calls, unprivileged storage accesses, and many others. Securify precisely analyzes real-world smart contracts within seconds and handles any language that compiles to Ethereum bytecode. Petar is a scientific researcher the Software Reliability Lab (http://www.srl.inf.ethz.ch/) at ETH Zurich and a co-founder of ChainSecurity (http://chainsecurity.com/), a blockchain security startup based in Zurich, Switzerland. He completed his PhD in the area of automated security analysis at ETH Zurich in 2016. Before that, Petar studied computer science at Georgia Tech (USA), where he completed his bachelor's degree. He has been working on automated security analysis of Ethereum smart contracts and general blockchain security topics for over a year now. For more information on projects and activities, have a look at http://chainpl.ethz.ch/ The focus of his talk will be on general security issues in smart contracts, the current state of security analysis tools for Ethereum contracts, and a demo of the Securify system. ChainSecurity will be presented at the end of the talk. Ana-Maria Yanakieva Although the hype around the ICOs seems to have piped down a little, they are still a popular method of fundraising and will most probably remain such in the foreseeable future. Many investors see them as a good opportunity for quick capital gains. However, it is still relatively difficult to select the right projects in the sea of ICOs. Moreover, the traditional valuation models are not working in the crypto market. We therefore need to adapt the well-known metrics to the new market structure. In her talk Ana-Maria will address valuation methods before and after the main ICO sale and will present some examples. Ana is currently a Blockchain Analyst for LAUNCHub Ventures (http://Launchub.vc/) and full time BSc Economics student at City, University of London. She is an editor for Sebfor (http://sebfor.com/). Ana also has an Economics and Management and Accountancy background. She is currently primarily working on ICO valuations and dealflow, as well as doing crypto trading every now and then. Ana is also an active member of the Sofia Crypto Meetup Facebook group.
The Math Major
This video covers the math major including applied math vs pure math, courses you'll take, and careers you can go into. The math major in undergrad involves a lot of the same classes whether you go into applied math or pure math include Calculus, linear algebra, differential equations, proofs, abstract algebra, real analysis, and more. But you will be able to take electives in pure or applied math concepts. Pure math is about using math to solve problems in math. Then applied math is about using math to solve problems outside of math (such as physics, engineering, finance, chemistry, biology, etc). Many pure math students end up getting their PhD so they can work in academia on research. Overall math students can go into a variety of fields including engineering, software development, teaching, finance, and more.

Square: Murky Crypto Accounting Rules Pose Risk
Square: Murky Crypto Accounting Rules Pose Risk Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator.The network is peer-to-peer and transactions take place between users directly, without an intermediary.These transactions are verified by network nodes through the use of cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. As of February 2015, over 100,000 merchants and vendors accepted bitcoin as payment.[14] Research produced by the University of Cambridge estimates that in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin. ► SUBSCRIBE FOR MORE VIDEOS: https://goo.gl/NYaHq2 ► Bitcoin News -Alt Coin news - coin telegraph - coindesk - coin market cap https://goo.gl/45UVFu ★★★ Thanks for watching!

Future Readiness for Accountants: Blockchain
Have you heard of blockchain before? Blockchain technology is on the rise, and it will have major implications on the future of accounting. So what exactly is a blockchain? A blockchain is a decentralized, chronological ledger protected by cryptography. The ledger is made up of a chain of blocks, which each contain information about transactions. For example, if you wanted to use a blockchain to track the ownership of a house, each block would contain information like the buyer, the seller, and the sale amount. Blockchains are like the general ledgers that accountants use every day. They’re non-destructive, so when a block needs to be changed, the original is left intact, and a new entry is made at the bottom of the ledger. That way, everyone can see when and why the change was made. Most people hear “blockchain” and think “Bitcoin,” but blockchain isn’t limited to just cryptocurrency. You can trade, record, and track almost anything with blockchain, including deeds, medical records, and financial transactions. Blockchains are peer-to-peer and decentralized, which means there’s no centralized bank or other trusted institution controlling transactions. Instead, individuals agree to verify and control transactions using their own computers and the software code that powers blockchain. Every personal computer is a single node in a vast, interconnected network, and every node has its own copy of the blockchain ledger that automatically updates when a new block is added. This decentralization means that blockchain is very secure. In a centralized system (such as a bank), hackers only have to attack one institution to gain access to the data they want. To attack a blockchain, hackers would have to attack every single node in the network. The security of blockchains makes them an ideal tool to use in accounting. Because they’re so secure and resistant to modification, blockchains can be used to securely process payments, record transactions, and execute documents. As a result, blockchain technology may replace certain aspects of an accountant’s job, such as bookkeeping, verifying transactions, maintaining and reconciling ledgers, and auditing. Blockchain will probably have the biggest impact on auditing. Blockchains are real-time, update faster than any human, and do it all with fewer errors. In some cases, auditors may not be needed to verify ledgers. With the power of blockchain, the day-to-day tasks of an auditor must be completely reimagined. However, this automation of routine tasks won’t make auditors a thing of the past. Instead, auditors will have more time and resources for higher-level thinking, research, and strategy. Instead of working on mundane tasks like recordkeeping or verifying ledgers, auditors will dive deep into data and provide valuable takeaways to their clients. Accountants will need to be interpreters between complex blockchain processes and clients. While every accountant won’t need to know the nitty-gritty of how blockchain technology works, they’ll need to be able to draw meaningful conclusions, give sound advice, and demystify blockchain for clients. Change is ahead, bringing fear and uncertainty for many. But blockchain technology doesn’t mean the end for accountants—instead, it’s an opportunity for accountants to reshape their roles, evolve their skills, and embrace a new technology that will help them supercharge their results.

DEF CON 21 - Ryan W Smith and Tim Strazzere - DragonLady An Investigation of SMS Fraud
DragonLady: An Investigation of SMS Fraud Operations in Russia RYAN W. SMITH SENIOR RESEARCH AND RESPONSE ENGINEER, LOOKOUT MOBILE SECURITY TIM STRAZZERE LEAD RESEARCH AND RESPONSE ENGINEER, LOOKOUT MOBILE SECURITY One of the top types of Android malware are trojans that claim to provide a useful service, but instead send SMS messages to premium shortcodes, charging the victims and putting money directly into the attackers' hands. We've seen a steady increase in this type of malware over the past years, and recently we've seen an increase in sophistication of obfuscation and distribution techniques as well. By investigating certain families of malware over time, we've seen encryption, code level obfuscation, on-demand build systems, and weekly code release cycles become more common. It became clear that there was significant organization and investment of both time and money behind several of these malware families, so we began following leads to find out how far the rabbit hole goes. This presentation will show key findings and methods of this investigation into top Android malware distributors operating in Russia and the surrounding region. The investigation includes the discovery of 10's of thousands of bot-controlled twitter accounts spreading links to this type of SMS fraud malware, tracing distribution through thousands of domains and custom websites, and the identification of multiple "affiliate web traffic monetization" websites based in Russia which provide custom Android SMS fraud malware packaging for their "affiliates". During this investigation we have mapped out an entire ecosystem of actors, each providing their own tool or trade to help this underground community thrive. Come out to this talk to find out how just how much effort and manpower is invested in defrauding Android users through this type of SMS trojan malware, and the types of organizations that are behind it. Ryan W. Smith (@ryanwsmith13) is a Senior Research and Response Engineer at Lookout, and has been an actively making and breaking software systems for the past 11 years. With a tendency to jump into anything sufficiently interesting and challenging, his projects range from automated x86 reverse engineering to large scale network attack graph analytics. As a chronic community contributor, Ryan may have been seen speaking at any number of Honynet Project, OWASP, AHA, or UT COMSOC events. Tim Strazzere is a Lead Research and Response Engineer at Lookout Mobile Security. Along with writing security software, he specializes in reverse engineering and malware analysis. Some interesting past projects include having reversing the Android Market protocol, Dalvik decompilers and memory manipulation on mobile devices.

10 Things You Didn't Know About Bitcoin
Here are 10 facts about the cryptocurrency known as Bitcoin, or BTC! From mining to blockchain technology, I'll tell you everything you need to know about Bitcoin basics. Get BTC here: https://www.coinbase.com/join/5926bddfea359f083d018d81 Bitcoin is a decentralized digital currency created in 2009 whose transactions are 1) peer-to-peer, and 2) recorded on a public ledger. While you technically can print your private key on paper in the form of a paper wallet, this is merely a code that gives you access to your electronic funds. Each transaction of this crypto currency recorded & verified on an open ledger so that each & every transaction (plus the transaction amount) is open & available to the public. But don’t worry, because despite transactions being broadcast out into the open, the identities of both the sender & receiver are protected by cryptographically-hidden serial numbers called public keys, which are long strings of numbers & letters that make it pretty much impossible to expose the identity behind it. The underlying technology is called the blockchain, which is the public ledger where each & every Bitcoin transaction is recorded, no matter how small or large the amount. The blockchain is made up of a network of nodes--or computers--that communicate with one another in order to ensure that the ledger is accurate. As soon as I send this Bitcoin, the transaction is broadcast to the blockchain, and several nodes within the network proceed to verify this transaction, add it to the public ledger, then send an updated copy of the ledger to all the other nodes in the network. It’s grouped into a “block” of other transactions & added to the chain of past blocks to forever go down in accounting history; hence the name “blockchain.” This sophisticated system of verification removes any possibility of double-spending a Bitcoin because if two or more nodes validating the same transaction come up with different amounts--and ultimately, differing ledgers--the transaction becomes void. As I stated earlier, the blockchain is comprised of a network of nodes, or computers. These nodes are responsible for maintaining the integrity of the blockchain by verifying transactions, updating the public ledger, and broadcasting this new version of the ledger to all the other nodes in the network. This whole process is called “mining,” and miners are incentivized by being rewarded a certain amount of Bitcoin for every transaction they verify. There’s a total available supply of 21,000,000 Bitcoin to be mined. As of today, new blocks are mined every 10 minutes on average, with each block generating 12.5 new Bitcoin as rewards to miners. This rate will continue until the year 2020, when 6.25 new Bitcoin are rewarded per mined block. Four years later, rewards will be halved again at 3.125 new Bitcoin rewarded per block. This “halving” process is set to occur every four years until the year 2140, when all 21,000,000 Bitcoin will have been mined & in circulation. Bitcoin was created by an unknown person who goes by the name Satoshi Nakamoto. The New Yorker believes it to be Irish cryptography student Michael Clear, while Vice thinks it’s either Gavin Andresen, Jed McCaleb, or Shinichi Mochizuki. Newsweek magazine claims it’s an old Japanese engineer from California whose name is actually Satoshi Nakomoto. Regarding safety, close to 32,500,000 blocks were mined in 2009 alone with a reward rate of 50 Bitcoin per block. Bit coin had just reached its all-time high of over $6,300 per coin. The Bitcoin crypto currency has come a long way since its inception in 2009. In fact, back in 2009, a man named Kristoffer Koch bought 5,000 Bitcoin for $27...that’s just over half a cent per Bitcoin! At the all-time high rate of $6,300 per Bitcoin, his 5,000 Bitcoin wallet would now be worth $31.5 million! Despite its price volatility, financial analysts & economists are predicting prices of this cryptocurrency to go up even further. 2015 reported over 100,000 merchants who officially accept the cryptocurrency called Bitcoin, the likes of which include PayPal, Expedia, & all Shopify-based stores. It’s been so revolutionary to the financial industry that banks, hedge funds, and even national governments are researching ways in which they can implement crypto currency both Bit coin & blockchain technology into their infrastructure. Early adopters show strong support for Bit coin due to its decentralized nature & how it can topple governments & financial institutions. But much of the rise in popularity can also be credited to pure hype. Its first all-time high peaked in 2013 at over $1,200 per coin, which “piqued” a lot of interest at the time.

"Aura: Programming with Authorization and Audit" (CRCS Lunch Seminar)
CRCS Lunch Seminar (Monday, November 2, 2009) Speaker: Jeff Vaughan, Harvard CRCS Title: Aura: Programming with Authorization and Audit Abstract: Standard programming models do not provide direct ways of managing secret or untrusted data. This is a problem because programmers must use ad hoc methods to ensure that secrets are not leaked and, conversely, that tainted data is not used to make critical decisions. This talk will advocate integrating cryptography and language-based analyses in order to build programming environments for declarative information security, in which high-level specifications of confidentiality and integrity constraints are automatically enforced in hostile execution environments. I will introduce describes Aura, a family of programing languages, which integrate functional programming, access control via authorization logic, automatic audit logging, and confidentially via encryption. Aura's programming model marries an expressive, principled way to specify security policies with a practical policy-enforcement methodology that is well-suited for auditing access grants and protecting secrets. Aura security policies are expressed as propositions in an authorization logic. Such logics are suitable for discussing delegation, permission, and other security-relevant concepts. Aura's (dependent) type system cleanly integrates standard data types, like integers, with proofs of authorization-logic propositions; this lets programs manipulate authorization proofs just like ordinary values. In addition, security-relevant implementation details—like the creation of audit trails or the cryptographic representation of language constructs—can be handled automatically with little or no programmer intervention. Bio: Jeff Vaughan's research lies at the intersection of computer security, programming languages, and formal methods. He is particularly interested in access control, information flow, the theory and application of dependent types, and mechanized metatheory. Jeff will be receiving his PhD from the University of Pennsylvania.

Worlds First BITCOIN ATM Opens in Vancouver Canada - Is CryptoCurrency the Future Currency?
PLEASE DONATE BITCOIN or LITECOIN to Support our Efforts BITCOIN: 18TndrqgZfHjPf7vv78jygxKF6vPfGwA7K LITECOIN: LSxSujEYKCG6T78DrDpnpzwDusgzca27as SUBSCRIBE http://www.youtube.com/BitcoinResearch Worlds First BITCOIN ATM Opens in Vancouver Canada - Is CryptoCurrency the Future Currency? It was the machine face that launched a thousand articles. News of the world's first real Bitcoin ATM being installed in a coffee shop in Vancouver, Canada on Tuesday set the media afire, with stories published across the globe. Whether related or not, in the day after the CND$ BTC machine went live, "Bitcoin" became the second most read article on Wikipedia, after "Halloween." Bitcoiniacs, which bought the $18,500 machine from Reno, Nevada-based Robocoin. While most of that is people buying Bitcoins, $6,000 worth of Bitcoins have been traded for Canadian cash. Demeter says he's planning to install four more Bitcoin ATMs around Canada. Financial regulators have told him they're not interested in his ATM as Canada doesn't regard Bitcoin as a currency. The machine's only nod toward the law is a palm scanner to ensure that no one palm exchanges more than $3,000 per day, per a federal requirement intended to prevent money laundering. But why is the world so excited about this machine? And why would anyone use it? The whole financial point of the peer-to-peer, decentralized currency is to make online money transmission easy and transaction-fee free. Though the machine makes a near instant exchange taking less than a minute reports Wired says there is a 3% fee to change money using the machine, making it pricier than most online exchanges. San Francisco-based Coinbase charges a 1% fee to change money to Bitcoin. Canadian Virtual Exchange has fees from .5% to 1.5%. "Why trundle down to a regular ATM to get bills to stuff into the Bitcoin ATM, when you could do the same transaction on your couch pay fewer fees?" writes Jeff John Roberts at Gigaom. While the machine does facilitate anonymity by allowing you to convert directly from cash to Bitcoin without attaching a bank account or identity credentials as you must with Bitcoin exchanges like Coinbase or, now, Mt. Gox have to scan a palm, leaving some identifying biometric information behind. Though part of the reason a palm was chosen is that it's a biometric not often used unless you're taking the GMAT. bitcoin "bitcoin atm" vancouver cafe "vancouver canada" "digital currency" cryptocurrency "online currency" atm cash forex "currency exchange" "bitcoin wallet" bank banking system government dollar euro "u.s. dollar" "bitcoin mining" economy future price mt.gox wallet debt "gold bullion" "gold coin" "silver bullion" fraud identity technology "bitcoin exchange" payment paypal alternative accounting "united states" "gold atm" trends trendy demand collapse ebay shopping "silver eagle" "U.S. mint" 2013 2014 agenda nwo 829speedy bitcoin trends research There was a race on to be the first to develop a Bitcoin ATM, with Robocoin primarily competing with New Hampshire-based Lamassu and BitcoinATM. Bitcoiniacs chose Robocoin because "they're the only ones that have a functioning product," says Demeter. "Everyone's talking about it but no one had anything ready." Despite the fact that the machine doesn't make much sense economically, I believe it got widespread coverage because of people's fascination with Bitcoin in the real world. People have trouble grasping the "mining" and cryptography and peer-to-peer network stuff, but an ATM that you put money into that shoots a Bitcoin address out? That's easily grasped. to digital forms of money. criminal activity. The two Senate hearings -- the first to focus on bitcoin -- are likely to examine how regulators are responding to the new forms of payment, the aides said. Potential points of discussion include how financial-industry regulators will watch over investment in the new currencies and how virtual currencies might impede tax collection or facilitate trade in illegal products out of the sight of law enforcement. online drug marketplace Silk Road. Bitcoin, which allows users to conduct online transactions while obscuring their identities, was the only currency accepted on Silk Road. Law enforcement officials arrested the site's alleged proprietor, Ross Ulbricht, earlier this month, and have shuttered the operation. Ulbricht faces a potentially lengthy prison sentence for charges ranging from narcotics trafficking to computer hacking to money laundering. Federal officials have now seized over $33.6 million worth of bitcoins in connection with the case.

Differential Computation Analysis: Hiding Your White-Box Designs is Not Enough
Although all current scientific white-box approaches of standardized cryptographic primitives are broken, there is still a large number of companies which sell "secure" white-box products. After an introduction to the concept of white-box cryptography, I will introduce a new approach to assess the security of white-box implementations which requires neither knowledge about the look-up tables used nor any reverse engineering effort. This differential computation analysis (DCA) attack is the software counterpart of the differential power analysis attack as applied by the cryptographic hardware community. We developed plugins to widely available dynamic binary instrumentation frameworks to produce software execution traces which contain information about the memory addresses being accessed. We show how DCA can extract the secret key from all publicly available (non-commercial) white-box programs implementing standardized cryptography by analyzing these traces to identify secret-key dependent correlations. This work received the best paper award at the Conference on Cryptographic Hardware and Embedded Systems (CHES) 2016 and is joint work with Charles Hubain, Wil Michiels, and Philippe Teuwen.

DEF CON 14 - Robert J. Hansen: Trust, But Verify: Auditing Proprietary DRE Systems
Robert J. Hansen: Trust, But Verify: Auditing Proprietary DRE Systems Abstract: In 2006 the Help America Vote Act (HAVA) rid the country of lever voting machines and punchcard ballots, and gave the states enormous budgets for buying electronic voting machines. What's still unresolved is how these electronic voting machines are going to be audited. Trying to keep track of many different vendors, each of which has many different machines, is like getting lost in a funhouse hall of mirrors. Yet, there is good news. The National Science Foundation has established a research group for electronic voting, ACCURATE. In this presentation, an ACCURATE researcher will start talking about the thorny problem of making sure voting machines are playing fair. Existing technologies, both proprietary and open source, will be criticized; and new technologies will be presented. Bio: Robert J. Hansen has a Bachelor of Arts in Computer Science, Cornell College, 1998. Master of Computer Science, the University of Iowa, 2006. Chief Security Geek for Yomu Inc., 2000.

2004-11-17 CERIAS -  An Anonymous Fair-Exchange E-Commerce Protocol
Recorded: 11/17/2004 CERIAS Security Seminar at Purdue University An Anonymous Fair-Exchange E-Commerce Protocol Indrakshi Ray, Colorado State University Many business transactions over the Internet involve the exchange of digital products between two parties -- electronic mails, digital audio and video, electronic contract signing and digital signatures, to name a few. Often these transactions occur between players that do not always have identifiable place of doing business and hence do not trust each other. Consequently, there exists ample scope for any of the parties involved, to misbehave and gain advantage over the other party. To overcome this problem researchers have proposed protocols that ensure fairness, that is, no party can gain an advantage even if the party misbehaves. Most works in this area focus on gathering evidence during the protocol execution that is used later, in case of a dispute. The actual handling of the dispute is done manually, after the protocol execution, and is outside the scope of the protocol. However, in an electronic commerce environment, where the merchants and customers may disappear quickly, such "after-the-fact" protection may be inadequate. In this work we propose an e-commerce protocol for trading digital products over the Internet. The novel features of our protocol include: (1) ensuring fair exchange, (2) not requiring manual dispute resolution in case of unfair behavior by any party, (3) assuring each party that the item he is about to receive is indeed the correct one, (4) not requiring the active involvement of a trusted third party unless a problem occurs, and (5) ensuring anonymity for the customer. Indrakshi Ray is an Assistant Professor of Computer Science at Colorado State University. She received her Ph.D. from George Mason University in the area of Information Technology. Her research spans the areas of computer security, e-commerce, database systems and formal methods. Her research is currently supported by grants from the Airforce Office of Scientific Research, the Airforce Research Laboratory, the Federal Aviation Administration and the National Science Foundation.

There are, at best, only ways to make insecure channels (e.g., couriers, homing pigeons, diplomatic bags, etc.) less insecure: padlocks (between courier wrists and a briefcase), loyalty tests, security investigations, and guns for courier personnel, diplomatic immunity for diplomatic bags, and so forth. In 1976, two researchers proposed a key exchange technique (now named after them)—Diffie–Hellman key exchange (D-H). This protocol allows two parties to generate a key only known to them, under the assumption that a certain mathematical problem (e.g., the Diffie–Hellman problem in their proposal) is computationally infeasible (i.e., very very hard) to solve, and that the two parties have access to an authentic channel. In short, that an eavesdropper—conventionally termed 'Eve', who can listen to all messages exchanged by the two parties, but who can not modify the messages—will not learn the exchanged key. Such a key exchange was impossible with any previously known cryptographic schemes based on symmetric ciphers, because with these schemes it is necessary that the two parties exchange a secret key at some prior time, hence they require a confidential channel at that time which is just what we are attempting to build. It is important to note that most cryptographic techniques are trivially breakable if keys are not exchanged securely or, if they actually were so exchanged, if those keys become known in some other way— burglary or extortion, for instance. An actually secure channel will not be required if an insecure channel can be used to securely exchange keys, and if burglary, bribery, or threat aren't used. The eternal problem has been and of course remains—even with modern key exchange protocols—how to know when an insecure channel worked securely (or alternatively, and perhaps more importantly, when it did not), and whether anyone has actually been bribed or threatened or simply lost a notebook (or a notebook computer) with key information in it. These are hard problems in the real world and no solutions are known—only expedients, jury rigs, and workarounds. Researchers have proposed and demonstrated quantum cryptography in order to create a secure channel. If the current understanding of this subject of quantum physics is adequate, quantum cryptography facilitates the exchange of theoretically uneavesdroppable, non-interceptable, non-tamperable data. The mechanism is related to the uncertainty relation. It is not clear whether the special conditions under which it can be made to work are practical in the real world of noise, dirt, and imperfection in which most everything is required to function. Thus far, actual implementation of the technique is exquisitely finicky and expensive, limiting it to very special purpose applications. It may also be vulnerable to attacks specific to particular implementations and imperfections in the optical components of which the quantum cryptographic equipment is built. While implementations of classical cryptographic algorithms have received worldwide scrutiny over the years, only a limited amount of public research has been done to assess security of the present-day implementations of quantum cryptosystems, mostly because they are not in widespread use as of 2014. Security definitions for a secure channel try to model its properties independently from its concrete instantiation. A good understanding of these properties is needed before designing a secure channel, and before being able to assess its appropriateness of employment in a cryptographic protocol. This is a topic of provable security. A definition of a secure channel that remains secure, even when used in arbitrary cryptographic protocols is an important building block for universally composable cryptography....

William Mougayar: "Blockchains: Past, Present and Future" | Talks at Google
The Business Blockchain charts new territory in advancing our understanding of the blockchain by unpacking its elements like no other before. William Mougayar anticipates a future that consists of thousands, if not millions of blockchains that will enable not only frictionless value exchange, but also a new flow of value, redefining roles, relationships, power and governance. In this book, Mougayar makes two other strategic assertions. First, the blockchain has polymorphic characteristics; its application will result in a multiplicity of effects. Second, we shouldn’t ask ourselves what problems the blockchain solves, because that gives us a narrow view on its potential. Rather, we should imagine new opportunities, and tackle even more ambitious problems that cross organizational, regulatory and mental boundaries. Drawing on 34 years of technology industry experience as an executive, analyst, consultant, entrepreneur, startup mentor, author, blogger, educator, thought leader and investor, William Mougayar describes a future that is influenced by fundamental shifts brought by blockchain technology as the catalyst for change. William Mougayar has been described as the most sophisticated blockchain business thinker. He is a blockchain industry insider whose work has already shaped and influenced the understanding of blockchain for people around the world, via his generous blogging and rigorous research insights. He is a direct participant in the crypto-technology market, working alongside startups, entrepreneurs, pioneers, leaders, innovators, creators, enterprise executives and practitioners; in addition to being an investor, advisor, and board member in some of the leading organizations in this space, such as the Ethereum Foundation, OpenBazaar and Coin Center.

10 Facts About Cardano EXPLAINED! | 10 사실 Cardano 소개!
Cardano ADA coin explained! This cryptocurrency improves scalability, interoperability, & sustainability. Here's what you need to know about the Cardano token, the Daedalus wallet, & the Ouroboros Praos consensus algorithm. Cardano is a 3rd generation blockchain protocol that enables its users to send & receive digital funds, while also supporting smart contracts as well as the development of decentralized applications. Its technological design is focused on security, flexibility, & scalability. Through its innovative software architecture, Cardano also aims to give users the option of attaching metadata to a transaction. Cardano features a layered design, giving it flexibility and enabling upgrades by way of soft forks. The first layer is the CSL (or Cardano Settlement Layer), which is home to their ADA cryptocurrency. The CSL handles all token-related economics and manages balances. ADA’s uses include depositing funds on an exchange, paying for goods and services, entering an application, or sending value between two parties. Transactions on the Cardano network will also be powered by ADA. The CSL will only hold the most basic transaction data, like the number of ADA transferred from one wallet to another. The second layer—called the Cardano Computation Layer (or CCL)--is a set of protocols that handle all functions related to smart contracts. The layers will allow for more focused updates & better protection of transaction privacy, while communication between them will be handled through sidechains. Cardano is built using the Haskell programming language. Governance in Cardano will be based on the blockchain, & its token holders will get to vote on proposed modifications to the platform. This move towards democratizing the blockchain’s future effectively decentralizes governance and will likely contribute to the prevention of hard forks. Daedalus is the wallet provided by Cardano's developers that will enable users to send and receive ADA. Daedalus does not hold your keys, effectively giving you full control of your money while also protecting your funds from attacks through the implementation of cryptography. It offers spending passwords & seeds for all your accounts. Wallets can be exported to paper certificates, thus enabling users to place their funds in cold storage for maximum security. Cardano’s consensus algorithm is one of the most important aspects about the platform. Consensus is achieved through the unique Ouroboros Praos, which its developers have described as a Provably Secure Proof-of-Stake Blockchain Protocol. It has a modular design with embedded future-proofing, and it’s the only proof-of-stake protocol that features mathematically proven security. Physical time in Ouroboros is divided into epochs, which are then split into slots. Slot leaders are randomly elected from the group of total stakeholders, and they essentially perform the same functions that miners perform in Bitcoin. Slot leaders can listen to transactions announced by other nodes, make a block out of said transactions, sign the block, then publish it to the network. Only the slot leader has the right to produce just one block during his slot. Transaction fees are collected in a pool & distributed to slot leaders at the end of each epoch. Election for slot leaders takes place through a distributed method of random number generation. Participants generate secret seeds, which—through an algorithm named FTS (Follow The Satoshi)--are then turned into the identifier for a single specific coin. The owner of that coin then becomes a slot leader. Ouroboros comes with some added benefits too; the first of which is that it doesn’t require the large computational resources typical of blockchains like Bitcoin, while also maintaining the same level of security. Ouroboros basically runs on the concept of honest majority. Slot leaders can maintain blocks on multiple chains. This allows for the possibility of simultaneously running multiple epochs in parallel. Slot leaders will be using a quantum resistant signature scheme upon signing a block. The developers are proposing a new type of technology called RINA (or Recursive InterNetwork Architecture). Nodes will be part of subnetworks, and they'll be able to communicate with one another if necessary, similar to the TCP/IP Internet protocol. Another aspect of scalability is handling the constantly growing data. Since data storage is still rather inexpensive right now, Cardano's development team doesn’t consider it an urgent matter. They're working towards the implementation of storage techniques like compression, partitioning, and pruning. Cardano aims at becoming an “Internet of Blockchains.” Disclaimer: This is not financial advice.

OCF for Resource-Constrained Environments
OCF for Resource-Constrained Environments - Kishen Maloor, Intel Corporation The IoT will be connected by smart edge devices with pertinent hardware having resource constraints. Such devices will execute in an environment defined by a selection of embedded OS, network stack, I/O and network layer/radio capabilities, all for which there are many options. Frameworks for standards based IoT are therefore confronted with the challenge of providing a consistent and maintainable codebase to employ across a diversity of deployments while staying lightweight. This technical talk will present a new open-source and small-footprint implementation of the OCF (Open Connectivity Foundation) standard for resource-constrained environments. It will provide an overview of its architecture and design choices and how they address the aforementioned challenges. It will also do a code walk through of a simple OCF application. The presenter is the lead developer of this project. About Kishen Maloor Kishen Maloor is a Senior Software Engineer at Intel Corporation. He has contributed to several research initiatives at Intel ranging from middleware for processing high frequency sensor data for Context Aware Computing to predictive analytics pipelines, developing expertise in Machine Learning and Natural Language Processing along the way. He now works at the Intel Open Source Technology Center and contributes to initiatives lead by the Open Connectivity Foundation (OCF) for IoT. He is the maintainer of the meta-oic Yocto software layer for the IoTivity project on embedded targets, and has authored OCF’s Bluetooth Low Energy GATT profile to enable OCF devices to communicate over BLE. He is currently leading the design and development of a small-footprint implementation of the OCF standard for resource-constrained environments.
