Episode 38 | August 22, 2018 You know those people who work behind the scenes to make sure nothing bad happens to you, and if they’re really good, you never know who they are because nothing bad happens to you? Well, meet one of those people. Dr. Brian LaMacchia is a Distinguished Engineer and he heads up the Security and Cryptography Group at Microsoft Research. It’s his job to make sure – using up-to-the-minute math – that you’re safe and secure online, both now, and in the post-quantum world to come. Today, Dr. LaMacchia gives us an inside look at the world of cryptography and the number theory behind it, explains what happens when good algorithms go bad, and tells us why, even though cryptographically relevant quantum computers are still decades away, we need to start developing quantum-resistant algorithms right now.

Companies raised too much money and were unable to drive the sales volume which supported their ambitious infrastructure and share price. Out of the ashes, new, unexpected business models around search and social rose up, creating some of the most valuable companies in the world. The crypto bubble burst in 2018, with speculation unable to maintain the rapid growth in the value of cryptocurrencies. Use cases for payments were limited, and companies were unable to ship projects which attracted significant users. Out of this bubble, we are starting to see new companies and business models which are attracting customers and creating value. One of these companies is ABRA, which is using the unique features of Bitcoin to create a global trading platform for currencies, stocks and ETFs.

Speaker: Emmanuel Bouillon Security Researcher Federated Identity is getting prevalent in corporate environments. True, solving cross domain access control to Web applications or services is a nagging issue. Today, unsatisfying traditional approaches based on duplicated user accounts or dangerous trust domain relationships are being replaced by neater solutions. One of them is getting more and more popular not only in academic but in corporate environments as well: Claims-based authorization relying on SAML tokens. This cross domain federated Web SSO solution allows applications or service providers to finely control their access while leaving the burden of users management to their authoritative domains. Authoritative domains also keep full control on what they disclose about their users: Very attractive. However most existing material explains developers how to leverage this technology while keeping them oblivious to the underlying protocols or (many) standards' complexity and intricacies. By taking a radically low level approach, API free, this talk is intended to security pen-testers or architects who have to cope with SAML based access control. The just necessary presentation of the standards involved will be given. Then the two main parts will focus on how to adapt existing tool set to be fully operational against SAML access control and to key aspects that need to be considered prior joining or creating such federation. Most of the points are implementation agnostic and can be applied to Shibboleth, SimpleSAMLPHP or Active Directory Federation Service for instance. As well, the presented tools are Burp Pro Extensions leveraging the Buby framework but can be easily be translated into everyone preferred toolset.

Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional ("symmetric") cryptography which relies on the same key to perform both. Public-key algorithms are based on mathematical problems which currently admit no efficient solution that are inherent in certain integer factorization, discrete logarithm, and elliptic curve relationships. It is computationally easy for a user to generate their own public and private key-pair and to use them for encryption and decryption. The strength lies in the fact that it is "impossible" (computationally infeasible) for a properly generated private key to be determined from its corresponding public key. Thus the public key may be published without compromising security, whereas the private key must not be revealed to anyone not authorized to read messages or perform digital signatures. Public key algorithms, unlike symmetric key algorithms, do not require a secure initial exchange of one (or more) secret keys between the parties. This video is targeted to blind users.

The Data Encryption Standard (DES, /ˌdiːˌiːˈɛs/ or /ˈdɛz/) is a previously predominant symmetric-key algorithm for the encryption of electronic data. It was highly influential in the advancement of modern cryptography in the academic world. Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards (NBS) following the agency's invitation to propose a candidate for the protection of sensitive, unclassified electronic government data. In 1976, after consultation with the National Security Agency (NSA), the NBS eventually selected a slightly modified version, which was published as an official Federal Information Processing Standard (FIPS) for the United States in 1977. The publication of an NSA-approved encryption standard simultaneously resulted in its quick international adoption and widespread academic scrutiny. Controversies arose out of classified design elements, a relatively short key length of the symmetric-key block cipher design, and the involvement of the NSA, nourishing suspicions about a backdoor. The intense academic scrutiny the algorithm received over time led to the modern understanding of block ciphers and their cryptanalysis. DES is now considered to be insecure for many applications. This is chiefly due to the 56-bit key size being too small; in January, 1999, distributed.net and the Electronic Frontier Foundation collaborated to publicly break a DES key in 22 hours and 15 minutes (see chronology). There are also some analytical results which demonstrate theoretical weaknesses in the cipher, although they are infeasible to mount in practice. The algorithm is believed to be practically secure in the form of Triple DES, although there are theoretical attacks. In recent years, the cipher has been superseded by the Advanced Encryption Standard (AES). Furthermore, DES has been withdrawn as a standard by the National Institute of Standards and Technology (formerly the National Bureau of Standards). This video is targeted to blind users.

Secure Channel (Schannel) is Microsoft's standard SSL/TLS Library underpinning services like RDP, Outlook, Internet Explorer, Windows Update, SQL Server, LDAPS, Skype and many third party applications. Schannel has been the subject of scrutiny in the past several years from an external perspective due to reported vulnerabilities, including a RCE. What about the internals? How does Schannel guard its secrets? This talk looks at how Schannel leverages Microsoft's CryptoAPI-NG (CNG) to cache the master keys, session keys, private and ephemeral keys, and session tickets used in TLS/SSL connections. It discusses the underlying data structures, and how to extract both the keys and other useful information that provides forensic context about connection. This information is then leveraged to decrypt session that use ephemeral cipher suites, which don't rely on the private key for decryption. Information in the cache lives for at least 10 hours by default on modern configurations, storing up to 20,000 entries for client and server each. This makes it forensically relevant in cases where other evidence of connection may have dissipated. Bio: Jake Kambic is a DFIR researcher and network penetration tester

We live in an era of mass surveillance. Private companies monitor our comings and goings, and ad-supported cloud services record and mine our online activities. At the same time, governments have been conducting extensive surveillance in the name of national security. To a large extent, citizens and lawmakers have accepted loss of privacy in exchange for increased security. Can computing technology promote both personal privacy and national security? Panelists will explore how state-of-the-art cryptography, security, networked systems, and data-management technology might enable government agencies to acquire actionable, useful information about legitimate targets of investigation without intruding upon the electronic activity of innocent parties. They will also address the need to use laws and policies in conjunction with technology to hold government agencies accountable for proper use of private information.

More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary. Since the development of rotor cipher machines in World War I and the advent of computers in World War II, the methods used to carry out cryptology have become increasingly complex and its application more widespread. Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary. It is theoretically possible to break such a system, but it is infeasible to do so by any known practical means. These schemes are therefore termed computationally secure; theoretical advances, e.g., improvements in integer factorization algorithms, and faster computing technology require these solutions to be continually adapted. There exist information-theoretically secure schemes that provably cannot be broken even with unlimited computing power—an example is the one-time pad—but these schemes are more difficult to use in practice than the best theoretically breakable but computationally secure mechanisms. The growth of cryptographic technology has raised a number of legal issues in the information age. Cryptography's potential for use as a tool for espionage and sedition has led many governments to classify it as a weapon and to limit or even prohibit its use and export. In some jurisdictions where the use of cryptography is legal, laws permit investigators to compel the disclosure of encryption keys for documents relevant to an investigation. Cryptography also plays a major role in digital rights management and copyright infringement of digital media.

Diffie–Hellman key exchange (D–H) is a specific method of exchanging cryptographic keys. It is one of the earliest practical examples of key exchange implemented within the field of cryptography. The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure communications channel. This key can then be used to encrypt subsequent communications using a symmetric key cipher. The scheme was first published by Whitfield Diffie and Martin Hellman in 1976, although it had been separately invented a few years earlier within GCHQ, the British signals intelligence agency, by James H. Ellis, Clifford Cocks and Malcolm J. Williamson but was kept classified. This video is targeted to blind users.

By: Moxie Marlinspike We won the war for strong cryptography, anonymous darknets exist in the wild today, and decentralized communication networks have emerged to become reality. These strategies for communicating online were conceived of in anticipation of a dystopian future, but somehow these original efforts have fallen short of delivering us from the most pernicious threats to privacy that we're now facing. Rather than a centralized state-based database of all our communication and movements, modern threats to privacy have become something much more subtle, and perhaps all the more sinister. This talk will explore these evolving trends and discuss some interesting solutions in the works.

Museum Legs—taken from a term for art fatigue—starts with a question: Why do people get bored and tired in art museums and why does that matter? As Whitaker writes in this humorous and incisive collection of essays, museums matter for reasons that have less to do with art as we know it and more to do with business, politics, and the age-old question of how to live. Maybe the great age of museums will yet be a great age of creativity and hopeful possibility in everyday life.

There is no one best tool for the job and on top of that some tools don't do a great job at anything. Often in the hands of general users the capabilities and limitations are not even thought of during testing. Point, click, done. The attack surface of modern web environments as well as their protection mechanisms have become more complicated and yet many tools have not adapted. Hey, Y2K called and it wants some applications tested. There is certainly no shortage of vulnerabilities in modern web environments but we should be looking beyond low hanging fruit at this point. In between fully automated scanners and manual testing lies a sweet spot for the identification of vulnerabilities. Some of the juiciest pieces of information are not found by vulnerability scanners but are found by humans creating custom tests. This is why semi-automated testing space is so important. All of this complicated blending of protection mechanisms, services, and RIA technologies means that moving in to the area of semi-automated testing can be fraught with failure. We detail how these failures can be avoided as well as provide a tool that solves some of these problems as well as provides analysis for your own tools and scripts.

This is an audio version of the Wikipedia Article: Jewish culture Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Judaism guides its adherents in both practice and belief, so that it has been called not only a religion, but an orthopraxy. Not all individuals or all cultural phenomena can be classified as either "secular" or "religious", a distinction native to Enlightenment thinking.Jewish culture in its etymological meaning retains linkage to the Jewish people's land of origin, the people named for the Kingdom of Judah, study of Jewish texts, practice of community charity, and Jewish history. The term "secular Jewish culture" therefore refers to many aspects, including: Religion and World View, Literature, Media, and Cinema, Art and Architecture, Cuisine and Traditional Dress, attitudes to Gender, Marriage, and Family, Social Customs and Lifestyles, Music and Dance. "Secular Judaism," is a distinct phenomenon related to Jewish secularization - a historical process of divesting all of these elements of culture from their religious beliefs and practices.Secular Judaism, derived from the philosophy of Moses Mendelssohn, arose out of the Haskalah, or Jewish Enlightenment, which was itself driven by the values of the Enlightenment. In recent years, the academic field of study has encompassed Jewish Studies, History, Literature, Sociology, and Linguistics. Historian David Biale has traced the roots of Jewish secularism back to the pre-modern era. He, and other scholars highlight the Dutch philosopher Baruch Spinoza, who was dubbed "the renegade Jew who gave us modernity" by scholar and novelist Rebecca Newberger Goldstein in an intellectual biography of him. Today, the subject of Jewish secularization is taught, and researched, at many North American and Israeli universities, including Harvard, Tel Aviv University, UCLA, Temple University and City University of New York which have significant Jewish alumni. Additionally, many schools include the academic study of Judaism and Jewish culture in their curricula. Throughout history, in eras and places as diverse as the ancient Hellenic world, in Europe before and after the Age of Enlightenment, in Al-Andalus, North Africa and the Middle East, in India and China, and in the contemporary United States and Israel, Jewish communities have seen the development of cultural phenomena that are characteristically Jewish without being at all specifically religious. Some factors in this come from within Judaism, others from the interaction of Jews with host populations in the diaspora, and others from the inner social and cultural dynamics of the community, as opposed to religion itself. This phenomenon has led to considerably different variations of Jewish culture unique to their own communities.

The study of women's history has been a major scholarly and popular field, with many scholarly books and articles, museum exhibits, and courses in schools and universities. The roles of women were long ignored in textbooks and popular histories. By the 1960s, women were being presented as successful as male roles. An early feminist approach underscored their victimization and inferior status at the hands of men. In the 21st century writers have emphasized the distinctive strengths displayed inside the community of women, with special concern for minorities among women.
