Abstract

One of the five AES finalists, MARS, makes use of a 9x32 s-box with very specific combinatorial, differential and linear correlation properties. The s-box used in the cipher was selected as the best from a large sample of pseudo randomly generated tables, in a process that took IBM about a week to compute. This paper provides a faster and more effective alternative generation method using heuristic techniques to produce 9x32 s-boxes with cryptographic properties that are clearly superior to those of the MARS s-box, and typically take less than two hours to produce on a single PC.
