Title / titre: Designing Cryptographically-Strong Substitution Boxes: Building Tricky Maps Is Tough

Abstract / résumé: Substitution boxes (or s-boxes) are cryptographic tools which have gained prominence in recent years. They are basically maps used in many popular encryption algorithms which are designed to help keep information secure from unauthorized parties. The historical development of s-boxes will be discussed and various criteria for secure s-boxes will be defined. In particular, the applications of diverse topics such as probability and algebra to mathematical techniques and considerations for designing s-boxes will be explained. Finally, several areas of current and future research will be addressed.

Prerequisites / choses nécessaires: This talk will assume no background in cryptography, but will require some knowledge of discrete mathematics.
