Algorithm Implementation and Sequence Analysis of Logistic Map and Henon Map

By Chaos is a complex non-linear and non-equilibrium dynamics process.This paper realizes the implementation of encryption and decryption on tet text file through using Logistic map and Henon map respectively.It is proved that chaotic map has the characteristics of extreme sensitivity on initial value,convenience,and class aperiodic random and so on through carrying out matlab simulation sequence analysis on sequences generated by chaotic map.Chaotic sequence is very suitable for being used as key stream generator in cryptographic algorithm,which constitutes a password system with good performance.
