Description
Novel public-key cryptosystems beyond RSA and ECC are urgently required to ensure long-term security in the era of quantum computing. One alternative to such established schemes is ideal lattice-based cryptography which offers elegant security reductions and versatile cryptographic building blocks such as the ring learning with errors (RLWE) problem. In this talk we will give an overview on current research dealing with the implementation and optimization of efficient ideal lattice-based cryptography on embedded software platforms. We will present results for public key encryption and digital signature schemes on a constrained 8-bit platform (Atmel AVR) and discuss basic building blocks like polynomial multiplication and discrete Gaussian sampling. At the end of the talk we will examine some open problems and challenges in this emerging field of research.

Attacking the Supersingular Isogeny Problem: From the Delfs–Galbraith algorithm to oriented graphs
Speaker : Arthur Herlédan Le Merdy - COSIC, KU Leuven
The threat of quantum computers motivates the introduction of new hard problems for cryptography.One promising candidate is the Isogeny problem: given two elliptic curves, compute a “nice’’ map between them, called an isogeny.In this talk, we study classical attacks on this problem, specialised to supersingular elliptic curves, on which the security of current isogeny-based cryptography relies.
