Using chaotic maps construct secure communication scheme

A secure communication scheme based on chaotic maps is proposed. Two chaotic maps are used in this scheme, with a symbolic sequence generated by a piecewise nonlinear chaotic map the messages sequence are transformed into a real value sequence, employing the chaotic masking technique this sequence is encrypted with a chaotic sequence generated 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. So, it is suitable for practical use in the secure communication. © 2010 Binary Information Press.
