DEF CON 23 - Eijah - Crypto for Hackers
 
55:52
Hacking is hard. It takes passion, dedication, and an unwavering attention to detail. Hacking requires a breadth of knowledge spread across many domains. We need to have experience with different platforms, operating systems, software packages, tools, programming languages, and technology trends. Being overly deficient in any one of these areas can add hours to our hack, or even worse, bring us total failure. And while all of these things are important for a well-rounded hacker, one of the key areas that is often overlooked is cryptography. In an era dominated by security breaches, an understanding of encryption and hashing algorithms provides a tremendous advantage. We can better hone our attack vectors, especially when looking for security holes. A few years ago I released the first Blu-Ray device key, AA856A1BA814AB99FFDEBA6AEFBE1C04, by exploiting a vulnerability in an implementation of the AACS protocol. As hacks go, it was a simple one. But it was the knowledge of crypto that made it all possible. This presentation is an overview of the most common crypto routines helpful to hackers. We'll review the strengths and weaknesses of each algorithm, which ones to embrace, and which ones to avoid. You'll get C++ code examples, high-level wrapper classes, and an open-source library that implements all the algorithms. We'll even talk about creative ways to merge algorithms to further increase entropy and key strength. If you've ever wanted to learn how crypto can give you an advantage as a hacker, then this talk is for you. With this information you'll be able to maximize your hacks and better protect your personal data. Speaker Bio: Eijah is the founder of demonsaw, a secure and anonymous content sharing platform, and a Senior Programmer at a world-renowned game development studio. He has over 15 years of software development and IT Security experience. His career has covered a broad range of Internet and mid-range technologies, core security, and system architecture. Eijah has been a faculty member at multiple colleges, has spoken about security and development at conferences, and holds a master’s degree in Computer Science. Eijah is an active member of the hacking community and is an avid proponent of Internet freedom.

Quantum Algorithms for Number Theory and their Relevance to Cryptography
 
01:07:57
I will report on recent results about quantum algorithms for solving computational problems in number theory. I will show how they impact the security of certain post-quantum cryptosystems. Shor's quantum algorithm for factoring large integers and solving the discrete logarithm problem has been the motivation for an entire new area of research in cryptology: namely "post-quantum" cryptography. It consists of designing new cryptographic primitives which will resist attacks from quantum computers. In a recent work in collaboration with Fang Song, I presented a quantum polynomial time algorithm for solving the so-called "Principal Ideal Problem" (among other things) in arbitrary fields. We will see how this impacts the security of some ring-based proposals for quantum resistant cryptography. In collaboration with David Jao and Anirudh Sankar, I also described a quantum algorithm which finds an isogeny between two given supersingular curves over a finite field, a hard problem on which some post-quantum cryptosystem rely. Finally, if there is enough time, I'll mention some recent work on factorization.

Mathematics Gives You Dropouts
 
11:20
Roger Schank and Andrew Hacker dispel math instruction. Mathematics is highly overrated for most people and teaching it to everyone is why the standards have become so low. It pointlessly challenges those without interest in it and completely narrows and limits the content for people who want to know more than just BORING algebra. Norman Wildberger shows that they can't even teach trigonometry CORRECTLY. When I hear that grade schools are trying to include calculus, I burst out in laughter. It's OUTDATED! These kids can't even do a dot product, let alone do loopy belief propagation on probabilistic graphical models or use autoencoders in place of singular value decomposition or principal component analysis. These kids know so few areas and algorithms. Not only is mathematics one of the most automatable subjects on earth, it largely FOLLOWS discoveries. No, the modern computer was NOT based upon Turing (rehashed the silly diagonalizations of Godel and Cantor) and the airplane wasn't discovered by studying Newton (simple action-reaction displacing air) or Navier-Stokes. The mathematician couldn't even say why wings can fly UPSIDE DOWN (simple angle of attack ). Even the jet engine was not a straightforward application of math. People all talk about Maxwell's equations (can be reduce to one equation with geometric algebra), but the actual discoverer (Faraday) was not very good at math. The charlatans get all the credit. Grassmann was actually a theologian and he discovered the most useful branch of math, which is linear algebra. He also set the bases for geometric algebra, which shows you that imaginary numbers are just an ugly hack. Idiots like Gauss wondered about 17-gons but with a piece of string and Archimedes' spiral one can trisect the angle, square the circle, inscribe polygons and do inverse trig. They just refused to use string! Trivial! A simple bisection algorithm gives you guaranteed roots to ANY degree polynomial (in about 10 lines of code), where Galois showed analytical methods fail at the meager 5th degree. Simple N-body algorithms also solve more than the pathetic limit proved by Poincare of two bodies! They're trivial algorithms with computers. Poincare dispelled 20th century set theory and called it a useless Bourbaki disease, like modernist art. No TRULY creative math is done using ZFC and modern analysis has been ripped to shreds by those like Doron Zeilberger and Solomon Feferman. The proofs don't even work logically! Analysis is really just a cover for finite algebra. If you study modern gauge theory, you will understand that physicists pretend to have problems like chiral fermions in the lattice but it has all been solved. String theory is a comical joke. Mathematicians pretend we need to study prime factoring for cryptography but lattice-based methods make this silly. Even GPS can forget about SR and GR, making them systematic calibration errors (much larger calibrations are to do with other phenomena). Optimization, bootstrapping, numerical methods, perturbation, approximation, finite element method, computational fluid flow, machine learning, computer algebra systems, etc... takes care of all the real world mathematics with little skill involved. Modern mathematics is more like post-modern art subsidized by the government, so Ivy League jerkoffs can live at the public's expense. Don't listen to the Sputnik propaganda.

Advances in the CM method for elliptic curves
 
54:00
The complex multiplication method (CM method) builds an algebraic curve over a given finite field GF(q) and having an easily computable cardinality. Used at first for elliptic curves, this method is one of the building blocks of the ECPP algorithm that proves the primality of large integers, and it appeared interesting for other applications, the most recent of which being the construction of pairing friendly curves. The aim of the talk is to recall the method, give some applications, and survey recent advances on several parts of the method, due to various authors, concentrating on elliptic curves. This includes class invariant computations, and the potential use of the Montgomery/Edwards parametrization of elliptic curves.

We consider here non-prime finite fields of very small extension degree: 1≤n≤6. These cases are interesting in pairing-based cryptography: the pairing output is an element in such a finite field. The discrete logarithm in that finite field must be hard enough to prevent from attacks in a given time (e.g. 10 years). Within the CATREL project we aim to compute DL records in finite fields of moderate size (e.g. in GF(pn) of global size from 600 to 800 bits) to estimate more tightly the hardness of DL in fields of cryptographic size (2048 bits at the moment). The best algorithm known to compute discrete logarithms in large finite fields (with small n) is the number field sieve (NFS) [...] Recording during the thematic meeting: ''Arithmetics, geometry, cryptography and coding theory'' the May 20, 2015 at the Centre International de Rencontres Mathématiques (Marseille, France) Filmmaker: Guillaume Hennenfent

The processing needed to factor them is too large to be practical 6:45 Shor's algorithm is fast enough to crack RSA. If one could build a quantum computer with enough quantum bits then use a machine language cycle time that is us or ms, then one could factor thousand bit numbers 7:50 When will they be built? Some say 10 years, others 50 8:45 What does a quantum computer look like? An architectural description is easier to describe. A quantum computer similar to a classical computer, a quantum computer is a co-processor that will co-exist with current forms of digital electronics 9:15 Shor's algorithm has a lot of common commands - if statements and for loops. But, quantum gates are used in a quantum processor 10:00 Because a quantum gate operates in time instead of space, the term "gate" isn't accurate 10:30 What quantum computers exist today? Some exist with just a few quantum bits. People claim they've created quantum computers with 21 quantum bits. But, there can be a lot of errors and noise. For example, can a proper setup and hold time be maintained? 11:50 The Schrodinger's Cat analogy - In reality, if you've put a piece of physics into a superimposed quantum state, a disturbance of it (photon impact) will cause it to collapse into the wrong state or collapse too early 13:15 Quantum bits have to be thoroughly isolated. We use vacuums or extreme cold temperatures (well below 1 degree Kelvin!) 13:45 Research companies making claims about the number quantum bits are not using solid state quantum computers. The isolation of a quantum computer isn't be perfect, so there's a short lifetime for the computation before the probability of errors get's too high. 14:35 Why do we use a superposition of states? Why does the timing matter? If it collapses at the wrong time it returns a wrong answer. Shor's algorithm makes it easy to check for the right answer. And, you get a remainder of 0 or your don't. If mod(x) = 0, you know the answer is correct. The computation only has to be reliable enough because you can check your answer 16:15 If the odds of getting the right answer is high enough, it's ok to get the wrong answer on occasion. 16:50 How do you write a quantum bit? It depends on the physical system. You can write a quantum bit by putting energy in the system, i.e. using a very small number photon pulse with a specific timing and phase 18:15 Keysight helps quantum computer researchers generate and measure pulses with high levels of precision The pulses are carefully timed and correlated with sub-nanosecond precision 19:40 What is a quantum bit? There are two common kinds. 1 - Ions in a vacuum trapped by lasers. The ions are static because they are held in place by standing waves. The vacuum can be at room temperature and the ions are low temp because they can't move 2. Josephson junctions in tank circuits (resonant circuit, LC circuit, tuned circuit) makes oscillations at microwave frequencies. Under the right conditions, they can behave like an abstract two state quantum system. You simply have to designate zero and one to different states of the system. Probabilities are the wrong description, it;s actually complex quantum amplitudes. 24:30 Stupid question section: "If you had Schrodinger's cat in a box, would you look or not?"

Panel: Quantum Computing: Security Game Changer - CyCon 2018
 
01:01:55
The NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) organised its 10th International Conference on Cyber Conflict (CyCon 2018) in Tallinn, on the theme of maximising effects in the cyber domain. In the coming years, quantum computers (QCs) will bring the biggest single advance in the information age. All the prototyped and proposed QCs can solve extremely large and specific problems – the kinds of problems that are intractable on even the largest computers today. Although only a few companies presently sell QC-related products, all areas of information processing – especially those relying on intractability – should prepare for the global availability of QCs. Much of cryptography is built on classical intractability (factoring numbers, finding elliptic curves, etc.), with implications for secrecy, privacy, key exchange and signatures. These will be vulnerable and easily broken by QC. As a result, much groundwork has been done on both post-QC cryptography and key-exchange, as well as QC-based cryptanalysis. By contrast, relatively little work has been done in other QC-based aspects of cybersecurity, such as malware generation and detection, advanced multi vector threat detection, mapping the cyber battlefield and optimising cyber battle plans. Many of these cybersecurity problems are very large-scale, involve search and optimisation and can likely be executed in new ways with QC giving an entirely new cyber conflict asymmetry. This panel will discuss the full breadth of QC’s impact on all aspects of cybersecurity, from cryptography to cyberwarfare. Panelists: 1. Prof. Barry C. Sanders, University of Calgary 2. Prof. Norbert Lütkenhaus, Institute for Quantum Computing, Department of Physics, University of Waterloo, Canada 3. Prof. Troy Lee, Associate Professor, Nanyang Technological University Moderator: Prof. Bruce W.

Aswath Damodaran: "The Value of Stories in Business" | Talks at Google
 
01:31:29
The world of investing/finance is divided into two camps. In one, you have the number-crunchers, who believe that the only things that matter are the numbers and that imagination/creativity are dangerous distractions. In the other, you have the storytellers, who build on the stories they tell about companies and how these stories will bring untold wealth. Each side believes it has a monopoly on the truth and looks with contempt at the other. Prof. Damodaran contends that stories matter, but only if they are connected with numbers. And numbers are empty, unless they are connected with narratives. In this talk, he looks at the process by which one might build narratives, check them against reality and convert them into valuations. Uber and Ferrari examples are used to illustrate the process.

Factorization
 
02:28
Factoring (called "Factorising" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions. Factorization is the decomposition of an object (for example, a number, a polynomial, or a matrix) into a product of other objects, or factors, which when multiplied together give the original. For example, the number 15 factors into primes as 3 × 5, and the polynomial x2 − 4 factors as (x − 2)(x + 2). In all cases, a product of simpler objects is obtained. The aim of factoring is usually to reduce something to “basic building blocks”, such as numbers to prime numbers, or polynomials to irreducible polynomials. Factoring integers is covered by the fundamental theorem of arithmetic and factoring polynomials by the fundamental theorem of algebra. The opposite of polynomial factorization is expansion, the multiplying together of polynomial factors to an “expanded” polynomial, written as just a sum of terms. Integer factorization for large integers appears to be a difficult problem. There is no known method to carry it out quickly. Its complexity is the basis of the assumed security of some public key cryptography algorithms. Modern techniques for factoring polynomials are fast and efficient, but use sophisticated mathematical ideas (see Factorization of polynomials). These techniques are used in the construction of computer routines for carrying out polynomial factorization in Computer algebra systems. The more classical hand techniques rely on either the polynomial to be factored having low degree or the recognition of the polynomial as belonging to a certain class of known examples and are not very suitable for computer implementation Students who are introduced to factoring as a primary method of solving quadratic equations might be surprised to know it is one of the newest methods of solving them -~-~~-~~~-~~-~- Please watch: "Theory of Quadratic Equations 10th Maths Ex No 2 .7 Complete Solution" https://www.youtube.com/watch?v=0UP-z-hsaxY -~-~~-~~~-~~-~-

An algorithm for numerically solving certain 2d equations. Brought to you by...you! https://patreon.com/3blue1brown Special thanks to these supporters: http://3b1b.co/winding-thanks Even though we described how winding numbers can be used to solve 2d equations at a high level, it's worth pointing out that there are a few details missing for if you wanted to actually implement this. For example, in order to determine how often to sample points, you'd want to have some bounds on the rate at which the direction of the output changes. We will perhaps discuss this more in a follow-on video!

Talking Allowed: Beauty in Unexpected Places: Aesthetics and Mathematics
 
20:18
Presentation by Dr Sam Baron (Lecturer, Philosophy, The University of Western Australia) as part of the Talking Allowed series at the Lawrence Wilson Art Gallery, on Tuesday 10 October 2017. Captions available. ---- Talking Allowed - Beauty in Unexpected Places: aesthetics and mathematics Choices in mathematics are often made for aesthetic reasons: a degree of freedom is added here to preserve symmetry; a partial derivative is employed there because it establishes harmony and so on. The use of aesthetic considerations in mathematics hides a deep mystery. Mathematicians make progress by following their aesthetic instincts. Soon enough their mathematical results are picked up in physics and used to describe nature. One striking example of contemporary relevance, is the use of results in number theory for cryptography. According to the number theorists G. H. Hardy, mathematicians pursuing results in number theory were producing art. This artistic endeavour seemed all but useless until it was picked up as the basis for cryptography and, subsequently, cyber security as we know it today (your home wi is protected by number theoretic cyphers, involving primes). Is, then, the beauty of mathematics a guide to the truth? And if so, what implications does this have for our understanding of mathematical and artistic practice and their relationship to the scientific method? ‘Talking Allowed’ is a series of presentations offered by the UWA Institute of Advanced Studies in collaboration with the UWA Cultural Precinct held at the Lawrence Wilson Art Gallery.
