Elliptic Curves, Cryptography and Computation
 
55:10
Much of the research in number theory, like mathematics as a whole, has been inspired by hard problems which are easy to state. A famous example is 'Fermat's Last Theorem'. Starting in the 1970's number theoretic problems have been suggested as the basis for cryptosystems, such as RSA and Diffie-Hellman. In 1985 Koblitz and Miller independently suggested that the discrete logarithm problem on elliptic curves might be more secure than the 'conventional' discrete logarithm on multiplicative groups of finite fields. Since then it has inspired a great deal of research in number theory and geometry in an attempt to understand its security. I'll give a brief historical tour concerning the elliptic curve discrete logarithm problem, and the closely connected Weil Pairing algorithm.

Pairings on Elliptic Curves - Parameter Selection and Efficient Computation
 
56:23
This talk is about efficient pairing computation on elliptic curves. I will discuss particularly implementation-friendly curves, the use of the polynomial parameter representation to compute pairings on BN curves, and reasons to use affine coordinates for pairings at high security levels. This contains joint work with P. Barreto, G. Pereira, M. Simplício Jr, P. Schwabe, R. Niederhagen, K. Lauter, and P. Montgomery.

AES Encryption 2: AddRoundKey, SubBytes and ShiftRows
 
21:09
In this vid we'll fill out the bodies to three of the steps in AES. These three steps are AddRoundKey, SubBytes and ShiftRows. The remaining steps to AES are rather fiddly, MixColumns and ExpandKey, so we'll look at those separately. I've also taken the opportunity to introduce Galois fields for the AddRoundKey section. AddRoundKey is really just a matter of performing XOR, but it helps to understand Galois fields before we come to the MixColumns step.

Endomorphisms, isogeny graphs, and moduli
 
01:07:26
I will present a retrospective of aspects of my thesis, in light of applications in the last 14 years since its birth. In particular, I will focus on explicit isogenies, moduli of elliptic curves and CM structure, the 'local' Galois module structures of l-torsion and l-isogeny graphs, and 'global' structure of action visa class groups and isogenies. The focus will be directed principally towards ordinary elliptic curves over finite fields, but I will discuss briefly the supersingular case and generalizations to higher dimension.

Recovering elliptic curves from their p-torsion - Benjamin Bakker
 
01:03:39
Benjamin Bakker New York University May 2, 2014 Given an elliptic curve EE over a field kk, its p-torsion EpEp gives a 2-dimensional representation of the Galois group GkGk over 𝔽pFp. The Frey-Mazur conjecture asserts that for k=ℚk=Q and p13p13, EE is in fact determined up to isogeny by the representation EpEp. In joint work with J. Tsimerman, we prove a version of the Frey-Mazur conjecture over geometric function fields: for a complex curve CC with function field kCkC, any two elliptic curves over kCkC with isomorphic pp-torsion representations are isogenous, provided pp is larger than a constant only depending on the gonality of CC. The proof involves understanding the hyperbolic geometry of a modular surface. For more videos, visit http://video.ias.edu

And discover all its functionalities: - Chapter markers and keywords to watch the parts of your choice in the video - Videos enriched with abstracts, bibliographies, Mathematics Subject Classification - Multi-criteria search by author, title, tags, mathematical area We give a survey of results which address the following generic question: How does a random elliptic curve over a finite field look like. This question has a rich variety of specfic interpretations, which depend on how one defines a random curve and what properties which are of interest. The former may include randomisation of the coefficients of the Weierstrass equation or the prime power defining the field, or both. The latter may include studying the group structure, arithmetic structure of the number of points (primality, smoothness, etc.) and certain divisibility conditions. These questions are related to such celebrated problems as Lang-Trotter and Sato-Tate conjectures. More recently the interest to these questions was re-fueled by the needs of pairing based cryptography. In a series of talks we will describe the state of art in some of these directions, demonstrate the richness of underlying mathematics and pose some open questions.

Martijn Grooten - Elliptic Curve Cryptography for those who are afraid of maths
 
28:37
Elliptic Curve Cryptography (ECC) is hot. Far better scalable than traditional encryption, more and more data and networks are being protected using ECC. Not many people know the gory details of ECC though, which given its increasing prevalence is a very bad thing. In this presentation I will turn all members of the audience into ECC experts who will be able to implement the relevant algorithms and also audit existing implementations to find weaknesses or backdoors. Actually, I won't. To fully understand ECC to a point where you could use it in practice, you would need to spend years inside university lecture rooms to study number theory, geometry and software engineering. And then you can probably still be fooled by a backdoored implementation. What I will do, however, is explain the basics of ECC. I'll skip over the gory maths (it will help if you can add up, but that's about the extent of it) and explain how this funny thing referred to as "point addition on curves" can be used to exchange a secret code between two entities over a public connection. I will also explain how the infamous backdoor in Dual_EC_DRGB (a random number generator that uses the same kind of maths) worked. At the end of the presentation, you'll still not be able to find such backdoors yourselves and you probably realise you never will. But you will be able to understand articles about ECC a little better. And, hopefully, you will be convinced it is important that we educate more people to become ECC-experts.

Vídeo original: https://youtu.be/iB3HcPgm_FI Welcome to part four in our series on Elliptic Curve Cryptography. I this episode we dive into the development of the public key. In just 44 lines of code, with no special functions or imports, we produce the elliptic curve public key for use in Bitcoin. Better still, we walk you through it line by line, constant by constant. Nothing makes the process clearer and easier to understand than seeing it in straight forward code. If you've been wondering about the secp256k1 (arguably the most important piece of code in Bitcoin), well then this is the video for you. This is part 4 of our upcoming series on Elliptic Curves. Because of such strong requests, even though this is part 4, it is the first one we are releasing. In the next few weeks we will release the rest of the series. Enjoy.

Elliptic Curve Cryptography, A very brief and superficial introduction

by Ron Garret Bay Area Lisp and Scheme Meetup http://balisp.org/ Sat 30 Apr 2016 Hacker Dojo Mountain View, CA Abstract This will be a beginner’s introduction to elliptic curve cryptography using Lisp as a pedagogical tool. Cryptography generally relies heavily on modular arithmetic. Lisp’s ability to change the language syntax and define generic functions provides opportunities to implement modular arithmetic operations much more cleanly than other languages. Video notes The audio for the introduction and for the questions from the audience is hard to hear. I will try to improve on that in the next batch of talks. — Arthur

Mobile: (0) 9952649690, Email: [email protected], web: www.jpinfotech.org, Blog: www.jpinfotech.blogspot.com This paper proposes an efficient pipelined architecture of elliptic curve scalar multiplication (ECSM) over GF(2m). The architecture uses a bit-parallel finite field (FF) multiplier accumulator (MAC) based on the Karatsuba–Ofman algorithm. The Montgomery ladder algorithm is modified for better sharing of execution paths. The data path in the architecture is well designed, so that the critical path contains few extra logic primitives apart from the FF MAC. In order to find the optimal number of pipeline stages, scheduling schemes with different pipeline stages are proposed and the ideal placement of pipeline registers is thoroughly analyzed. We implement ECSM over the five binary fields recommended by the National Institute of Standard and Technology on Xilinx Virtex-4 and Virtex-5 field-programmable gate arrays. The three-stage pipelined architecture is shown to have the best performance, which achieves a scalar multiplication over GF(2163) in 6.1µs using 7354 Slices on Virtex-4. Using Virtex-5, the scalar multiplication form=163, 233, 283, 409, and 571 can be achieved in 4.6, 7.9, 10.9, 19.4, and 36.5 µs, respectively, which are faster than previous results. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2.

Elliptic curve cryptography
 
18:25
Elliptic curve cryptography is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography is the same level of security provided by keys of smaller size. Elliptic curves are applicable for encryption, digital signatures, pseudo-random generators and other tasks. They are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic curve factorization. This video is targeted to blind users.
