The Chaotic Cipher Based on CNNs and Its Application in Network

摘要

This paper studied the chaotic cipher based on CNNs chaotic equation and its application in the network environment. Firstly, a improve method for CNNs chaotic properties was given, the variables which has better statistic property and more sensitive to the system parameter be get to generate binary sequence for encrypt. And then, for applying chaotic cipher in network environment, the synchronization method based on the state variables transmission mechanism was proposed, this method can solve the synchronization problem of chaotic stream cipher, and the simulation test results confirm the validity. At last, a chaotic cryptosystem key distribution strategy in network environment was designed.
