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.

One&Done: A Single-Decryption EM-Based Attack on OpenSSL’s Constant-Time Blinded RSA Monjur Alam Georgia Tech Abstract: This paper presents the first side channel attack approach that, without relying on the cache organization and/or timing, retrieves the secret exponent from a single decryption on arbitrary ciphertext in a modern (current version of OpenSSL) fixed-window constant-time implementation of RSA. Specifically, the attack recovers the exponent’s bits during modular exponentiation from analog signals that are unintentionally produced by the processor as it executes the constant-time code that constructs the value of each “window” in the exponent, rather than the signals that correspond to squaring/multiplication operations and/or cache behavior during multiplicand table lookup operations. The approach is demonstrated using electromagnetic (EM) emanations on two mobile phones and an embedded system, and after only one decryption in a fixed-window RSA implementation it recovers enough bits of the secret exponents to enable very efficient (within seconds) reconstruction of the full private RSA key. Since the value of the ciphertext is irrelevant to our attack, the attack succeeds even when the ciphertext is unknown and/or when message randomization (blinding) is used. Our evaluation uses signals obtained by demodulating the signal from a relatively narrow band (40 MHz) around the processor’s clock frequency (around 1GHz), which is within the capabilities of compact sub-\$1,000 software-defined radio (SDR) receivers. Finally, we propose a mitigation where the bits of the exponent are only obtained from an exponent in integer-sized groups (tens of bits) rather than obtaining them one bit at a time. This mitigation is effective because it forces the attacker to attempt recovery of tens of bits from a single brief snippet of signal, rather than having a separate signal snippet for each individual bit. This mitigation has been submitted to OpenSSL and was merged into its master source code branch prior to the publication of this paper.

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/

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.

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.

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.

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.

Das wohl wichtigste ungelöste Problem der Mathematik. * Weihnachtsvorlesung 2018 (mehrere Teile) ab hier: http://weitz.de/y/UpQ8z50maV4?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * Weihnachtsvorlesung 2017 (mehrere Teile) ab hier: http://weitz.de/y/TOcQ_jIYQwo?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * "Alternative" Weihnachtsvorlesung 2017: http://weitz.de/y/Vv3Rve3yXBY?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * Weihnachtsvorlesung 2015: http://weitz.de/y/q2iZDtotiM0?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * Weihnachtsvorlesung 2014 (mehrere Teile) ab hier: http://weitz.de/y/40Mt9WdSNEk?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * Weihnachtsvorlesung 2013 (mehrere Teile) ab hier: http://weitz.de/y/2w1_kWn-F0s?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * "Sommervorlesung" 2014: http://weitz.de/y/BNx0ObN6fVc?list=PLb0zKSynM2PAuxxtMK1bxYPV_bUoPtpTB * zu "1+2+3+...=-1/12" siehe https://youtu.be/YuIIjLr6vUA * Das Buch: https://youtu.be/t0F-ua7vZZo Da dieser Vortrag, der ursprünglich vor nur etwa fünfzig Zuhörern gehalten wurde, inzwischen zu meiner Überraschung auf YouTube äußerst populär geworden ist, muss ich doch mal etwas klarstellen: Es handelt sich hier nicht um eine Vorlesung für Mathematiker, sondern um einen einmaligen "populärwissenschaftlichen" Vortrag, der sich an ein bunt gemischtes Publikum richtete; darunter auch viele "Laien", die nur Schulwissen der Mathematik mitbrachten (und das wahrscheinlich auch schon vergessen hatten). Es ging darum, Zuhörern, die sonst nichts mit Mathe am Hut haben, anhand eines Beispiels eine Vorstellung davon zu vermitteln, welche Fragen Mathematiker eigentlich beschäftigen.

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.
