Cryptography Research
Cryptography Research IBM and the Future of Cyber Security By 2011, the world will be 10 times more instrumented than it was in 2006. Internet connected devices will leap from 500 Million to 1 Trillion. Approximately 70% of the digital universe is created by individuals, but enterprises are responsible for 85% of the security, privacy, reliability, and compliance. Increasingly, the proliferation of data-generating sensors and mobile computing devices, and the emergence of new forms of communication such as social networking, are driving unprecedented growth in the collection, storage and management of all types of data. Not surprisingly, this phenomenon has sparked growing demand for the ability to extract intelligence from these massive mountains of information—intelligence that can enable organizations to improve their decision-making and run their businesses more effectively and efficiently. With this capacity to rapidly sift thru data and gain new insights comes a significant challenge and responsibility when it comes to personal information, or information that relates to identifiable individuals: how to enable the exchange and analysis of data, while protecting privacy. IBM has long recognized the importance of information privacy and led by example in its own privacy polices and practices: the company was the first multinational to adopt a global privacy policy in the late 1960s, and continued that leadership as recently as 2005 when it was the first company to address genetic privacy. But policies and practices are not enough on their own to address the privacy challenges of an increasingly smarter planet. Thoughtfully-designed technologies can play a key role here, part of a paradigm that some are calling Privacy by Design. As the world becomes smarter and more interconnected, the capacity to rapidly sift through data to gain new insights brings with it a significant challenge and responsibility when it comes to personal information. How do we enable the exchange and analysis of data, while protecting privacy? IBM, which in the 1960s because the first multinational to adopt a global privacy policy and in 2005 was the first to address genetic privacy, has long recognized the importance of information privacy. Leading by example in its own privacy polices and practices, IBM has also received many patents for inventions that support our commitment to privacy leadership. For example, an IBM Researcher has solved a thorny mathematical problem that has confounded scientists since the invention of public-key encryption several decades ago. The breakthrough, called "privacy homomorphism," or "fully homomorphic encryption," makes possible the deep and unlimited analysis of encrypted information -- data that has been intentionally scrambled -- without sacrificing confidentiality. IBM's solution, formulated by IBM Researcher Craig Gentry, uses a mathematical object called an "ideal lattice," and allows people to fully interact with encrypted data in ways previously thought impossible. With the breakthrough, computer vendors storing the confidential, electronic data of others will be able to fully analyze data on their clients' behalf without expensive interaction with the client, and without seeing any of the private data. With Gentry's technique, the analysis of encrypted information can yield the same detailed results as if the original data was fully visible to all. Using the solution could help strengthen the business model of "cloud computing," where a computer vendor is entrusted to host the confidential data of others in a ubiquitous Internet presence. It might better enable a cloud computing vendor to perform computations on clients' data at their request, such as analyzing sales patterns, without exposing the original data. Other potential applications include enabling filters to identify spam, even in encrypted email, or protecting information contained in electronic medical records. The breakthrough might also one day enable computer users to retrieve information from a search engine with more confidentiality http://asmarterplanet.com/

Q&A: HAIC Talk: Hard problems for Cryptography - with Chris Brzuska
Watch Chris Brzuska’s talk here: https://youtu.be/7H4qN73Y36Q Chris Brzuska answers questions about hard problems for cryptography, hosted by Andrew Paverd. Description: Cryptographers use hard problems to construct unbreakable encryption schemes, pseudorandom number generators and more. A typical example is the factoring of large numbers, i.e., we learn in primary school how to multiply numbers, but given a large number, even supercomputers struggle to take it apart into its prime factors. In the talk, we will see the diversity of hard problems that are candidates for secure cryptography, ranging from factoring to sudoku. About the speaker: Christopher Brzuska is a faculty member at the departments computer science and mathematics and systems analysis at Aalto University. His research area is cryptography and his activities range from investigating secure payment to generating numbers that look random although they are actually not. Brzuska studied mathematics in Duisburg-Essen, Bordeaux and Darmstadt, holds a PhD from the computer science department at TU Darmstadt and worked as a post-doctoral researcher at Tel-Aviv University and Microsoft Research Cambridge. He was an assistant professor for IT Security Analysis at TU Hamburg where he closely collaborated with NXP Semiconductors. HAIC Talks is a series of public outreach events on contemporary topics in information security, organized by the Helsinki-Aalto Center for Information Security (HAIC).

Stanford Seminar - The Evolution of Public Key Cryptography
EE380: Computer Systems Colloquium Seminar The Evolution of Public Key Cryptography Speaker: Martin Hellman, Stanford EE (Emeritus) While public key cryptography is seen as revolutionary, after this talk you might wonder why it took Whit Diffie, Ralph Merkle and Hellman so long to discover it. This talk also highlights the contributions of some unsung (or "under-sung") heroes: Ralph Merkle, John Gill, Stephen Pohlig, Richard Schroeppel, Loren Kohnfelder, and researchers at GCHQ (Ellis, Cocks, and Williamson). Resources and Reading Materials M. E. Hellman, Cybersecurity, Nuclear Security, Alan Turing, and Illogical Logic (http://www-ee.stanford.edu/ %7Ehellman/publications/77.pdf), Communications of the ACM, Vol. 60, No. 12, pp. 52-59, December 2017. This is a written version of Martin Hellman's ACM Turing Lecture (https://www.youtube.com/watch?v=I132wSwAI3o) and was accompanied by a short (6 minute) video (https://vimeo.com/241030842). Other materials and hard to find references can be found on Martin Hellman's Stanford website, http://www-ee.stanford.edu/~hellman/ . About the Speaker: Martin E. Hellman is Professor Emeritus of Electrical Engineering at Stanford University and is affiliated with the university's Center for International Security and Cooperation (CISAC). His recent technical work has focused on bringing a risk informed framework to a potential failure of nuclear deterrence and then using that approach to find surprising ways to reduce the risk. His earlier work included co- inventing public key cryptography, the technology that underlies the secure portion of the Internet. His many honors include election to the National Academy of Engineering and receiving (jointly with his colleague Whit Diffie) the million dollar ACM Turing Award, the top prize in computer science. His most recent project is a book, jointly written with his wife of fifty years, "A New Map for Relationships: Creating True Love at Home & Peace on the Planet," that provides a "unified field theory" of peace by illuminating the connections between nuclear war, conventional war, interpersonal war, and war within our own psyches.

Interview Igor Shparlinski : Jean Morlet Chair (First Semester 2014)
Jean-Morlet Chair on 'Number Theory and its Applications to Cryptography' Beneficiaries : Jean-Morlet Chair : Igor SHPARLINSKI School of Mathematics and Statistics University of New South Wales Sydney, Australia [email protected] Local project leader : David KOHEL I2M - Institut de Mathématiques de Marseille Aix-Marseille Université [email protected] General themes This chair was linked in parts to the thematic month on 'Arithmetics' which took part in February 2014 at CIRM. Igor Shparlinski has a career in Number theory and its applications to cryptography, with significant overlap with the research interests of the groups Dynamique Arithmétique, Combinatoire (DAC) and Arithmétique et Théorie de l'Information (ATI) in Marseille. The idea was to start the month with a week on 'Unlikely Intersections' followed by a workshop organized by members of the DAC research group. Weeks 3 and 4 were on 'Frobenius distributions' and were co-organized with the ATI group. The focus was to introduce and explore new directions of research around the proof of the Sato-Tate conjecture, its generalizations, and the related Lang-Trotter conjecture. Continuing the progression to the interactions of arithmetics with geometry, the thematic month closed with a week on the topic 'On the Conjectures of Lang and Volta'. The project was concentrated around several areas of number theory and its applications to quasi-Monte Carlo methods and cryptography. For both applications, the notion of pseudorandomness plays a very crucial role and thus they both require high quality pseudorandom number generators and randomness extractors. In turn, these applications lead to several subtle questions of analytic and combinatorial number theory, which are of intrinsic mathematical interest and involve the study of distribution of integers with prescribed arithmetic or combinatorial structure (e.g primes or smooth numbers and numbers with prescribed digit expansions). One of the new directions envisaged was to obtain polynomial analogues of several important results and conjectures which are known in the number case. Furthermore, driven by applications to elliptic curve cryptography, the project also addressed several theoritic and algorithmic questions related to elliptic and higher genus curves. The above applications were used on a combination of advanced number theory methods such as a) bounds of exponential and character sums; b) sieve methods and c) Subspace theorem and other Diophantine methods, which are developed by the members of DAC as well as the methods of algebraic geometry and commutative algebra such as d) effective forms of Hilbert's Nullstellensatz; e) Newton polytopes and f) Hilbert's Irreducibility theorem, which are developed by the members of ATI. The potential applications to pseudorandomness are of main interest to the members of DAC, while the applications to elliptic curve cryptography are one of the main directions of ATI. More specifically, the project consisted of the following closely related and cross-fertilising areas: 1. Pseudorandom number generators 2. Integers of cryptographic interest 3. Distribution of points in small boxes on curves over finite fields 4. Arithmetic and group theoretic properties of elliptic curves over finite fields. Interview : July 2014 By Stéphanie Vareilles

A Secure Key Predistribution Scheme for WSN Using ECC and HCC
Security in wireless sensor networks (WSNs) is an upcoming research field which is quite different from traditional network security mechanisms.Many applications are dependent on the secure operation of a WSN,and have serious effects if the network is disrupted. Therefore,it is necessary to protect communication between sensor nodes.Key management plays an essential role in achieving security in WSNs.To achieve security, various key predistribution schemes have been proposed in the literature. A secure key management technique in WSN is a real challenging task.In this project, a novel approach to the above problem by making use of Elliptic Curve Cryptography (ECC) and Hyperelliptic Curve Cryptosystem(HECC) is presented.In the proposed scheme, a seed key, which is a distinct point in an elliptic curve, is assigned to each sensor node prior to its deployment. The private key ring for each sensor node is generated using the point doubling mathematical operation over the seed key. When two nodes share a common private key, then a link is established between these two nodes. By suitably choosing the value of the prime field and key ring size, the probability of two nodes sharing the same private key could be increased. The performance is evaluated in terms of connectivity and resilience against node capture. The results show that the performance comaprsion for the proposed scheme ECC and HECC with polynomial genus 2.
Quantum Optics – Quantum cryptography the BB84 QKD scheme
One-photon based quantum technologies In this lesson, you will discover two quantum technologies based on one photon sources. Quantum technologies allow one to achieve a goal in a way qualitatively different from a classical technology aiming at the same goal. For instance, quantum cryptography is immune to progress in computers power, while many classical cryptography methods can in principle be broken when we have more powerful computers. Similarly, quantum random number generators yield true random numbers, while classical random number generators only produce pseudo-random numbers, which might be guessed by somebody else than the user. This lesson is also an opportunity to learn two important concepts in quantum information: (i) qubits based on photon polarization; (ii) the celebrated no-cloning theorem, at the root of the security of quantum cryptography. Learning Objectives • Apply your knowledge about the behavior of a single photon on a beam splitter to quantum random number generators. • Understand the no-cloning theorem • Understand and remember the properties of q qubit This course gives you access to basic tools and concepts to understand research articles and books on modern quantum optics. You will learn about quantization of light, formalism to describe quantum states of light without any classical analogue, and observables allowing one to demonstrate typical quantum properties of these states. These tools will be applied to the emblematic case of a one-photon wave packet, which behaves both as a particle and a wave. Wave-particle duality is a great quantum mystery in the words of Richard Feynman. You will be able to fully appreciate real experiments demonstrating wave-particle duality for a single photon, and applications to quantum technologies based on single photon sources, which are now commercially available. The tools presented in this course will be widely used in our second quantum optics course, which will present more advanced topics such as entanglement, interaction of quantized light with matter, squeezed light, etc... So if you have a good knowledge in basic quantum mechanics and classical electromagnetism, but always wanted to know: • how to go from classical electromagnetism to quantized radiation, • how the concept of photon emerges, • how a unified formalism is able to describe apparently contradictory behaviors observed in quantum optics labs, • how creative physicists and engineers have invented totally new technologies based on quantum properties of light, then this course is for you.

What is a zero-knowledge proof?
One of the more elegant and counterintuitive ideas in modern cryptography is the notion of a zero-knowledge proof (ZNP). A ZNP allows one party (the prover) to prove to another (the verifier) that they know a secret without revealing any information about the secret itself.It’s a totally wild idea that has deep implications for online security.

Exploring the arithmetic world and the natural world of mathematics
Kurihara Laboratory Department of Mathematics, Faculty of Science and Technology, Keio University "Exploring the arithmetic world and the natural world of mathematics" Kurihara Laboratory in the Department of Mathematics, Faculty of Science and Technology at Keio University, conducts research on number theory, which is a theory having a long history for more than 4,000 years, and which is still a quite active and important research area in mathematics. For example, in number theory many new results are still being proven even recently as seen in the proofs of Fermat's last theorem and of Iwasawa main conjecture. Number theory is also applied to cryptology and code theory. "My current research topic is mainly Iwasawa theory which is an important branch of number theory. Iwasawa theory studies, for example, ideal class groups, Selmer groups, and Mordell-Weil groups which are groups of rational solutions on certain curves, and the relations with the values of analytic zeta functions and with the p-adic L-functions which are p-adic analogues of zeta functions. Usually such relations are formulated as the Iwasawa main conjectures, which are the core of Iwasawa theory. But in our study we are finding deeper and finer relations between these objects, and study them. " The main feature of Kurihara's group lies in the research on Iwasawa theory. The Iwasawa main conjecture is the core of Iwasawa theory, which describes the relationship between Iwasawa modules, which have important arithmetic information, and the p-adic L-functions, which are incarnations of analytic zeta functions in the p-adic world. Kurihara's group study the more refined relationships between Iwasawa modules and p-adic zeta functions than the main conjecture, and further pursue a better formulation of them and the generalization to many aspects. Applying these ideas, they study various number theory problems. "I think mathematics is a natural science in which we study and search the natural world of mathematics. In particular, number theory treats numbers which are a real existence. I guess you can feel the sense of presence from very explicit problems like finding rational solutions of some equations." "I guess people usually think of mathematics as solving just difficult problems, as in high school mathematics and the entrance examinations to universities. So most people think that mathematics is just making difficult problems and solving them, but real mathematics is not like that. It is a natural science which studies the nature of the world of mathematical existence. " Iwasawa theory is also used to prove Fermat's Last Theorem, and is a theory widely researched in Europe, the USA, and all over the world. Kurihara Laboratory is very active in this field, and has held very successful international conferences on Iwasawa theory. "We will further continue to hold international conferences and workshops and to provide many opportunities for students to also attend and speak there. We would also like to invite world leading researchers from around the world. We will continue to research internationally."

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.

#HITB2017AMS COMMSEC D1 - Fault Injection Attacks On Secure Boot - Niek Timmers and Albert Spruyt
Today’s standard embedded technology is not resilient against basic hardware fault injection attacks. Such attacks alter the intended behavior of a chip by manipulating its environmental conditions. Typically this is done by manipulating the power supply voltage, but more advanced techniques use electro-magnetic or optical pulses. Code bases which are executed at the highest privilege level are of special interest to attackers, because modified behavior can have much impact on the security of the whole system. Whereas common software vulnerabilities are very powerful, such code is typically well protected against pure logical attacks. An example is secure boot, a common embedded system security feature to assure the integrity and confidentiality of all code executed after power-on reset. With fault injection it is possible to override restrictions or skip protective code, which enables a hostile takeover of the system. This talk provides an introduction to fault injection attacks on embedded systems and explains their impact on secure boot using multiple practical examples. As a key take away from this talk we present practical mitigation techniques for implementers of secure boot to lower the probability of a successful attack. === Niek Timmers is a Senior Security Analyst at Riscure where he analyzes and tests, among other things, the security of System-on-Chips (SoC) and Embedded Systems. At the moment his primary research topic is fault injection on feature rich chips. However, never a week goes by without disassembling, analyzing or emulating some random binary. Shared his research at multiple conferences such as FDTC and Black Hat. --- Albert Spruyt is a Senior Security Analyst at Riscure, where he tries to best systems. He is fascinated by the area where crypto rubber meets the hardware road. Where he builds stuff to take things apart. Spoke at HITB before.
