Abstract

In this paper, we present a novel digital encryption algorithm using discrete-time chaotic synchronization. The boundedness property of chaotic systems is exploited to realize the encryption and decryption procedure. Different from previous approaches of encrypting messages by chaotic systems, the proposed method focuses on digital signals instead of analog ones. Moreover, after synchronization, the transmitted signal has the same bit-length as the information data which is to be transmitted. The chaotic signal in the encryptor depends on the information message and cannot be predicted by the decryptor independently. Our simulation results based on an application to image encryption with Hénon map validate the proposed method.
