The use of the block cipher to construct a Hash function is a very common method.The most representative algorithm is Whirlpool.This algorithm has the same packet length as the output length,but its efficiency is half that of AES-128.We obtain a message extension improvement program of Whirlpool with the thought of AES-256,while increasing the iterative rounds.The efficiency of this algorithm is about 1.4 times higher than that of the original algorithm with the security of the algorithm remaining unchanged.

Key words: Whirlpool;key expansion;Hash
