Course info

Prerequisites

Basics of linear algebra, finite groups and fields, probability theory, preferably also the Mastermath Cryptology course as taught in Fall 2017 (see https://hyperelliptic.org/tanja/teaching/crypto16/)

Aim of the course

To provide insight into

• the design of symmetric cryptography:
  • permutations and blockciphers: linear, differential and higher-order differential cryptanalysis, wide trail strategy, the importance of alignment;
  • modes: sponge, duplex etc., both keyed and unkeyed.
• public key cryptanalysis:
• classical cryptanalysis: factoring and (finite field and elliptic curve) discrete logarithms analysis, index calculus, quadratic sieve, number field sieve;
• special cryptanalysis: Coppersmith methods and other lattice based attacks, fault injection, all-pairs gcd computation, etc.
• cryptanalysis of lattice-based systems: enumeration, sieving, locality based hashing, attacks on ideal lattices, etc.
