IMPROVEMENT OF THE RESISTANCE TO CRYPTANALYTIC ATTACKS OF A HASH FUNCTION

摘要

Improvement of the resistance to cryptanalytic attacks of a hash function. The invention relates to a method of transforming a first data message (M) of any length into a third data message (H) of determined length comprising: - a step of pseudo-randomly generating (A) a second data message (N) on the basis of the first message (M); - a step (B) of compressing said second message (N) into a third data message (H).
