%X A class scheme of hash function was introduced and the flaws and security holes were pointed out.Then,a modified algorithm for one-way Hash function construction based on the spatiotemporal chaotic system was proposed.Analysis shows that the proposed algorithm has better statistics performance and efficiency,and remedies the security holes of the original algorithm.
