The Design and Implementation of Password Authentication System Based on Chaos

This paper proposed the construction algorithm of chaotic Hash function based on Hénon-like mapping, and designed one password authentication scheme on basis of chaotic scramble sort algorithm and chaotic Hash function; it also resolved the insecurity problems that can’t resist little numbers attack, the iteration times of plaintext transmission and the attack of fraud server in the scheme. It finally implemented the one time password authentication system based on chaotic scramble sort table and chaotic Hash function.
