Abstract

In view of chaos synchronization systems sensitivity to parameter mismatches, a new class of chaotic secure communication schemes based on the discrete time chaos noise generator is proposed. In this scheme it is easy to adjust the level of systems security by raising its exponent or increasing its mapping iteration times. Studying results show this new scheme can resist the attack of adaptive synchronization and has better security properties, when compared with the formal schemes based on the decomposition of low dimensional chaotic systems, and it can be implemented easily.
