Abstract

We propose a new family of hash functions based on computations over a finite field of characteristic 2. These functions can be computed quickly, detect small modifications of the input text, and their security is equivalent to a precise mathematical problem. They rely on the arithmetic of the group of matrices SL2, and improve upon previous functions based on the same strategy.
