Congruence (Modular Arithmetic) & 5 Properties Explained with 7 Problems: Ultimate Shortcuts
 
51:44
Modular arithmetic especially the properties of congruence are an important tool in arriving at quick solutions to a variety of problems. In this video Mayank unravels this concept of Congruence starting with the basic concepts and then explaining the 5 key properties of Congruence (≡): a+c ≡ (b+d)mod N (Remainder of Sums ≡ Sum of Remainders) a-c ≡ (b-d)mod N (Remainder of Difference ≡ Difference of Remainders) ac ≡ (bd)mod N (Remainder of Products ≡ Products of Remainders) a^e ≡ b^e mod N (Remainder of Exponent ≡ Exponent of Remainders) a/e ≡ b/e (mod N/gcd(N,e)) (However, don’t do division without writing basic equation Mayank applies these concepts to arrive at quick solutions for 7 representative problems - reducing seemingly impossible math involving large numbers to mere seconds. Some example problems from the video: Find the remainder 6^(6^(6^6 ) )/7 Find the last digit of (17)^16 There are 44 boxes of chocolates with 113 chocolates in each box.

Modular Arithmetic
 
20:02
A visualization of modular arithmetic around a circle, created with python. The circle is divided up with 0 and 300 at point 0 or 2π on the unit circle. The white number is the multiplicative coefficient of the visualization. Every line is a multiplication with the coefficient in modulo 300, and the colour of the lines represents a decimal from 0 to 9. I got the idea from this Wolfram Alpha demonstration by Jaime Rangel-Mondragon: http://demonstrations.wolfram.com/GeneratingACardioidVIIJoiningPointsOnACircle/ Music by me and mamoulian69 (past Daddysmilk)

That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In simple cases the logarithm counts factors in multiplication. For example, the base 10 logarithm of 1000 is 3, as 10 to the power 3 is 1000 (1000 = 10 × 10 × 10 = 103); 10 is used as a factor three times. More generally, exponentiation allows any positive real number to be raised to any real power, always producing a positive result, so the logarithm can be calculated for any two positive real numbers b and x where b is not equal to 1. The logarithm of x to base b, denoted logb(x), is the unique real number y such that by = x. For example, log2(64) = 6, as 64 = 26. The logarithm to base 10 (that is b = 10) is called the common logarithm and has many applications in science and engineering. The natural logarithm has the number e (≈ 2.718) as its base; its use is widespread in mathematics and physics, because of its simpler derivative. The binary logarithm uses base 2 (that is b = 2) and is commonly used in computer science. Logarithms were introduced by John Napier in the early 17th century as a means to simplify calculations. They were rapidly adopted by navigators, scientists, engineers, and others to perform computations more easily, using slide rules and logarithm tables. Tedious multi-digit multiplication steps can be replaced by table look-ups and simpler addition because of the fact—important in its own right—that the logarithm of a product is the sum of the logarithms of the factors: log b ⁡ ( x y ) = log b ⁡ ( x ) + log b ⁡ ( y ) , {\displaystyle \log _{b}(xy)=\log _{b}(x)+\log _{b}(y),\,} provided that b, x and y are all positive and b ≠ 1. The present-day notion of logarithms comes from Leonhard Euler, who connected them to the exponential function in the 18th century. Logarithmic scales reduce wide-ranging quantities to tiny scopes. For example, the decibel is a unit quantifying signal power log-ratios and amplitude log-ratios (of which sound pressure is a common example). In chemistry, pH is a logarithmic measure for the acidity of an aqueous solution. Logarithms are commonplace in scientific formulae, and in measurements of the complexity of algorithms and of geometric objects called fractals. They describe musical intervals, appear in formulas counting prime numbers, inform some models in psychophysics, and can aid in forensic accounting. In the same way as the logarithm reverses exponentiation, the complex logarithm is the inverse function of the exponential function applied to complex numbers. The discrete logarithm is another variant; it has uses in public-key cryptography.

CppCon 2018: “Multi-Precision Arithmetic for Cryptology in C++, at Run-Time and at Compile-Time”
 
31:29
http://CppCon.org Niek J. Bouman “Multi-Precision Arithmetic for Cryptology in C++, at Run-Time and at Compile-Time” — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — In the talk, I will present a new C++17 library for multi-precision arithmetic for integers in the order of 100--500 bits. Many cryptographic schemes and applications, like elliptic-curve encryption schemes and secure multiparty computation frameworks require multiprecision arithmetic with integers whose bit-lengths lie in that range. The library is written in “optimizing-compiler-friendly” C++, with an emphasis on the use of fixed-size arrays and particular function-argument-passing styles (including the avoidance of naked pointers) to allow the limbs to be allocated on the stack or even in registers. Depending on the particular functionality, we get close to, or significantly beat the performance of existing libraries for multiprecision arithmetic that employ hand-optimized assembly code. Beyond the favorable runtime performance, our library is, to the best of the author’s knowledge, the first library that offers big-integer computations during compile-time. For example, when implementing finite-field arithmetic with a fixed modulus, this feature enables the automatic precomputation (at compile time) of the special modulus- dependent constants required for Barrett and Montgomery reduction. Another application is to parse (at compile-time) a base-10-encoded big-integer literal. In this talk, I will focus on some Modern C++ language features that I've used to write the library and design its API (e.g., std::array, variadic templates, std::integer_sequence, constexpr, user-defined literals, using-declarations and decltype, and combinations thereof). Also, I will show some benchmarks, and will argue that the integer types offered by the library compose well with STL containers or other libraries (like Eigen for matrix/linear algebra operations). I will also present some results on formal verification of correctness and the "constant-time" property: - Correctness is verified using a tool named SAW (Software Analysis Workbench), which tries to prove equivalence between the compiled C++ code (represented as LLVM bitcode) and a behavioral specification given in a high-level functional language; - "Constant-timeness" is a property that is crucial for implementations of cryptographic protocols to prevent timing attacks. In particular, I succeeded to verify my C++ code with "ct-verif", a tool for verifying the constant-time property for C programs (which was, in its original form, incompatible with C++ due to usage of non-ANSI C in one of its header files) The library is on Github (Apache 2 licensed) https://github.com/niekbouman/ctbignum — Niek J.

Fiat Cryptography: Automatic Correct-by-Construction Generation of Low-Level Cryptographic Code
 
01:05:21
Some of the most widely used cryptographic protocols, including TLS, depend on fast execution of modular big-number arithmetic. Cryptographic primitives are coded by an elite set of implementation experts, and most programmers are shocked to learn that performance-competitive implementations are rewritten from scratch for each new prime-number modulus and each significantly different hardware architecture. In the Fiat Cryptography project, we show for the first time that an automatic compiler can produce this modulus-specialized code, via formalized versions of the number-theoretic optimizations that had previously only been applied by hand. Through experiments for a wide range of moduli, compiled for 64-bit x86 and 32-bit ARM processors, we demonstrate typical speedups vs. an off-the-shelf big-integer library in the neighborhood of 5X, sometimes going up to 10X. As a bonus, our compiler is implemented in the Coq proof assistant and generates proofs of functional correctness. These combined benefits of rigorous correctness/security guarantees and labor-saving were enough to convince the Google Chrome team to adopt our compiler for parts of their TLS implementation in the BoringSSL library. The project is joint work with Andres Erbsen, Jade Philipoom, Jason Gross, and Robert Sloan.  See more at https://www.microsoft.com/en-us/research/video/fiat-cryptography-automatic-correct-by-construction-generation-of-low-level-cryptographic-code/

Bulletproofs: Short Proofs for Confidential Transactions and More
 
30:01
One of the inherent values of cryptocurrency is that transactions are publicized and verified across the network, thus making it very difficult--or even impossible--to compromise. However, with this key benefit comes two significant downfalls of this system: the transaction amounts are public and the addresses (owners) are easily decoded. How does this affect the potential uses of cryptocurrency if it were to be adopted by mainstream? Join Benedikt Bunz as he analyzes some of the key issues with keeping crypto transactions private and presents an optimistic solution. This presentation is brought to you by the Stanford Computer Forum and the Stanford Advanced Computer Security Program.

ShmooCon 2014: SafeCurves: Choosing Safe Curves for Elliptic-Curve Cryptography
 
01:02:25
For more information visit: http://bit.ly/shmooc14 To download the video visit: http://bit.ly/shmooc14_down Playlist Shmoocon 2014: http://bit.ly/shmooc14_pl Speakers: Daniel J. Bernstein | Tanja Lange There are several different standards covering selection of curves for use in elliptic-curve cryptography (ECC). Each of these standards tries to ensure that the elliptic-curve discrete-logarithm problem (ECDLP) is difficult. ECDLP is the problem of finding an ECC user's secret key, given the user's public key. Unfortunately, there is a gap between ECDLP difficulty and ECC security. None of these standards do a good job of ensuring ECC security. There are many attacks that break real-world ECC without solving ECDLP. The core problem is that if you implement the standard curves, chances are you're doing it wrong: Your implementation produces incorrect results for some rare curve points. Your implementation leaks secret data when the input isn't a curve point. Your implementation leaks secret data through branch timing. Your implementation leaks secret data through cache timing. These problems are exploitable by real attackers, taking advantage of the gaps between ECDLP and real-world ECC. Secure implementations of the standard curves are theoretically possible but very hard. Most of these attacks would have been ruled out by better choices of curves that allow simple implementations to be secure implementations. This is the primary motivation for SafeCurves, http://safecurves.cr.yp.to/. The SafeCurves criteria are designed to ensure ECC security, not just ECDLP security.

A new algorithm for long integer cube computation - CASC 2012 (Part II)
 
10:49
Alberto Zanoni's new approach for the computation of long integer cube (third power) based on a splitting-in-two divide et impera approach and on a modified Toom-Cook-3 unbalanced method is presented, showing that the "classical" square-and-multiply algorithm is not (always) optimal. The new algorithm is used as a new basic tool to improve long integer exponentiation: different techniques combining binary and ternary exponent expansion are shown. Effective implementations by using the GMP library are tested, and performance comparisons are presented.

Codebreakers Trailer (Sneak Peak)
 
02:21
Codebreakers was created by Strange Loop Games www.strangeloopgames.com Create security systems made out of equations to protect your vault, trapping your friends when they try to break into your room and steal your trophy. In c0d3bre4k3rs, players create and solve intricate puzzles combining math and game characters like the guard, janitor, and IT guy that will interfere or help in your heist plans. Play through a single player campaign following Max and Min through three locales, unlocking new puzzle elements to be used in multiplayer. Steal your friends’ trophies or capture friends in your own traps to earn money to build bigger and better trophies and rooms. c0d3bre4k3rs is the first and only social algebra game. Extended description A wide range of mathematical concepts of varying difficulty can be fit into this puzzle framework, and playing Codebreakers will build understanding of these concepts: • Algebraic expressions • Single and multi-variable equations • Negative numbers • Exponents and roots • Decimals Because the more difficult concepts will be more expensive to purchase, a natural progression is created that starts players off creating simple puzzles and growing them in difficulty as they gain expertise in creating and solving puzzles. Codebreakers will progress the difficulty slowly, starting with very simple puzzles that are easy to solve through trial and error and building towards equations that would be very difficult to solve without understanding algebraic tools like variable isolation and substitution. Because the difficulty increases smoothly, the player can become invested in the game and be immediately rewarded before being challenged. When they do reach mathematical concepts they can't solve, they will thus see them as the next step on a progression of things they can understand, and be driven to discover how to solve them. Through the game, they will see the need and usefulness of algebraic tools. Codebreakers takes a unique approach to learning – it does not aim to teach players the algebraic tools they will need to solve these puzzles. Instead, Codebreakers aims to fill a gap in math education: to provide students an evident and interesting purpose to algebra, a usefulness related to their interests. This effect is amplified through the social design of the game: players will see their friends succeeding and gaining prestige and trophies through algebraic expertise. They will see difficult puzzles created by their friends that they know their friends have solved (because they can only submit a puzzle they were able to solve, and they can see trophies players have collected from solved puzzles). In the game world of Codebreakers, mathematical skill translates directly to wealth and prestige, and players will seek to solve and create the most difficult puzzles, which can only be achieved by understanding the most difficult math concepts. The tools the player will need to solve the more difficult puzzles will be learned outside the game; Codebreakers's role is not to teach them but to provide a usefulness for them. As they become engaged with the game students will relate concepts they learn in class to puzzles in Codebreakers, discuss solving puzzles with their friends, find answers by looking online, etc. It follows the model of popular games for that age group like Minecraft and Terraria that require researching external wikis in order to succeed. Like those games, Codebreakers is designed knowing that it doesn't exist in a vacuum and relies on students to seek out answers externally. By providing a lock that the player cares about but not the key, Codebreakers drives the player to self-directed learning, research, discussion, and attention in class.

That means the logarithm of a number is the exponent to which another fixed number, the base, must be raised to produce that number. In simple cases the logarithm counts factors in multiplication. For example, the base 10 logarithm of 1000 is 3, as 10 to the power 3 is 1000 (1000 = 10 × 10 × 10 = 103); 10 is used as a factor three times. More generally, exponentiation allows any positive real number to be raised to any real power, always producing a positive result, so the logarithm can be calculated for any two positive real numbers b and x where b is not equal to 1. The logarithm of x to base b, denoted logb(x), is the unique real number y such that by = x. For example, log2(64) = 6, as 64 = 26. The logarithm to base 10 (that is b = 10) is called the common logarithm and has many applications in science and engineering. The natural logarithm has the number e (≈ 2.718) as its base; its use is widespread in mathematics and physics, because of its simpler derivative. The binary logarithm uses base 2 (that is b = 2) and is commonly used in computer science. Logarithms were introduced by John Napier in the early 17th century as a means to simplify calculations. They were rapidly adopted by navigators, scientists, engineers, and others to perform computations more easily, using slide rules and logarithm tables. Tedious multi-digit multiplication steps can be replaced by table look-ups and simpler addition because of the fact—important in its own right—that the logarithm of a product is the sum of the logarithms of the factors: log b ⁡ ( x y ) = log b ⁡ ( x ) + log b ⁡ ( y ) , {\displaystyle \log _{b}(xy)=\log _{b}(x)+\log _{b}(y),\,} provided that b, x and y are all positive and b ≠ 1. The present-day notion of logarithms comes from Leonhard Euler, who connected them to the exponential function in the 18th century. Logarithmic scales reduce wide-ranging quantities to tiny scopes. For example, the decibel is a unit quantifying signal power log-ratios and amplitude log-ratios (of which sound pressure is a common example). In chemistry, pH is a logarithmic measure for the acidity of an aqueous solution. Logarithms are commonplace in scientific formulae, and in measurements of the complexity of algorithms and of geometric objects called fractals. They describe musical intervals, appear in formulas counting prime numbers, inform some models in psychophysics, and can aid in forensic accounting. In the same way as the logarithm reverses exponentiation, the complex logarithm is the inverse function of the exponential function applied to complex numbers. The discrete logarithm is another variant; it has uses in public-key cryptography.

Usable formal methods - are we there yet?
 
45:07
Stefan Götz https://linux.conf.au/schedule/30141/view_talk Creating safe and secure software is hard, and counter-intuitively even harder in tiny embedded devices - devices that drive you, fly you, inject you with medicine, or keep your heart beating. We present how we have prevented bugs in embedded systems with open-source tools for formal methods. The big advantage of formal methods is that they can intercept bugs before code is built or run. Therefore, they avoid the difficulties of the classic approaches: testing, run-time checking, or re-using standard code. Our experience is based on static analysis with splint and model checking with CBMC for the eChronos real-time operating system. Safety-critical applications, such as UAV research and commercial medical devices rely on eChronos as their core OS. The formal methods tools are part of our development process and Continuous Integration system, so they help find bugs both in the OS itself and in the application code. This presentation shows how we apply splint and CBMC to real-world code and the practical lessons we have learned in the process. This includes: - a brief overview of the fundamental strengths and weaknesses of each approach and tool - the bugs we have found and the classes of bugs the tools prevent - how to apply the tools to a code base in practice, what is needed to support the tools, and how to maintain that support - the scalability and some limitations and bugs of the tools themselves, and where theory and practice do not line up - how such tools and formal methods in general can influence software design (which is usually to the better) Overall, formal methods have matured to be practical and valuable for real-world code in a real-world development process. The available open-source tools may require a design or code tweak here or there, but are well past purely academic relevance.

Between Testing and Formal Verification - Jan Tobias Muehlberg
 
54:02
The security testing of software is inherently difficult. This is because vulnerabilities typically emerge as unanticipated interactions in the design of a software component, as implementation artefacts that were not specified in the design, or as bugs, where design and implementation deviate. Thus, when searching for breaches of security properties we are looking for design or implementation details that can be abused in ways not considered by the designers, developers and testers of a software component. Formal methods promise to systematise this search for needles in haystacks and use mathematical rigour to provide convincing arguments for the absence of such needles. Yet, with few exceptions in safety-critical systems engineering, the adoption of formal techniques in software development processes is low. Furthermore, formal methods traditionally focus on safety aspects of software, i.e., functional correctness and the absence of runtime exceptions of software. In this talk I will outline the advantages and disadvantages of modern approaches to formal software analysis and verification. I will focus on tools and techniques that can be integrated efficiently with testing efforts, in particular in security testing. Jan Tobias Muehlberg work as a researcher at imec-DistriNet, KU Leuven (BE). I am active in the fields of software security, and formal verification and validation of software systems, specifically for embedded systems and low-level operating system components. I am particularly interested in security architectures for safety-critical embedded systems and for the Internet of Things.

Numerical Tools for Non-Experts
 
01:07:07
Developing reliable numerical software has traditionally been a tedious process which requires significant expertise. Recently, our team at the University of Washington has been investigating how tools may lower the barrier to entry for non-experts. This talk discusses two such tools, Herbgrind and Herbie, that help non-expert developers debug and improve their programs. Herbgrind uses a dynamic program analysis that finds root causes for numerical problems in program binaries. Herbgrind instruments program binaries to additionally compute over shadow values that track floating-point operations in higher precision, then uses a taint analysis to find possible causes for erroneous outputs. To recover the context of root cause instructions, it uses anti-unification to build up an abstract representation of instruction inputs. Herbie uses heuristic search to find more-accurate ways of evaluating floating-point formulas. Herbie uses a variety of rewriting strategies to modify the input formula, focusing changes on the part of the formula responsible for the most error. Then, multiple modified formulas can be combined based into one by finding regions of the input space where they are more accurate.

ShmooCon 2014: Practical Applications of Data Science in Detection
 
58:04
It seems recently offensive tactics, exploits and vulnerabilities are getting all the Info Sec sexy-points. We're going to try and swing this back towards detection as we apply some new-fangled math and techniques to solve some existing problems and tackling new ones. We'll take Data Science off its pedestal and show how, with problem and data understanding you can apply different techniques to make analysis more exciting and effective. We'll use several open source tools and libraries to perform the data exploration and analysis, including iPython and pandas as well as a data hacking library we've already released. After discovering some useful patterns we'll show how we were able to implement the results so that they can be used for actual network analysis (with some real-world results). Some of the use cases used to demonstrate the concepts will be passive browser fingerprinting and SQL injection detection. Audience members are welcome and encouraged to play buzzword bingo. Brian Wylie's interests are data analysis, machine learning and information visualization. Current projects include a breadth of work applying data analysis to security problems. Brian has been a long time advocate of open community projects including the Visualization ToolKit (VTK) and the Titan Informatics Toolkit. Brian's Erdˆs number is 3. Mike Sconzo has been around the Security Industry for quite some time, and really enjoys looking at network traffic. He has recently been using various data analysis techniques to look security related data in a new light where before he'd just use a hex editor.

Google Tech Talk September 24, 2009 slides: http://www.slideshare.net/jchrisa/couchdb-local-web-platform Web Exponents: http://www.youtube.com/view_play_list?p=689D6EE903ED5CB6&search_query=web+exponents ABSTRACT Presented by Chris Anderson. CouchDB's web API and offline replication capabilities make it ideally suited to power a sea-change in the relationships between users and service providers. I'll give a 10,000 foot overview of CouchDB, as well as discuss the benefits and challenges of writing applications that can be replicated transparently from the cloud to local machines. Chris Anderson is an Apache CouchDB committer and co-author of the forthcoming O'Reilly book "CouchDB: The Definitive Guide". He is a director of couch.io, offering commercial hosting, support, consulting, and custom development. He enjoys working on JavaScript CouchApps which can be peer-replicated just like any other data. Chris is obsessed with bending the physics of the web to give control back to users.
