Abstract

A secure communication algorithm based on piecewise liner chaotic map is proposed.Two chaotic maps are used in this algorithm,with a symbolic sequence generated by a chaotic map the message sequence is tracked,employing the chaotic masking technique the message for transmitted is encrypted with a binary sequence extracted from another chaotic map.The theoretic and experience results stated that the proposed algorithm has many properties such as high speed and easy implementing and high security and it is suitable for practical use in the secure communication.
