Abstract

This paper considers the problem of chaos synchronization based on fuzzy sliding mode control and its applications to image encryption. We applied the fuzzy sliding mode controller to achieve chaos synchronization. Then, the Duffing-Holmes chaos states are used to act as the encryption key of cipher text. When their initial values of chaotic states are different, the state sequences are uncorrected. This concept is employed to communication secrecy and image encryption. The XOR operation is used to realize image encryption. The numerical results demonstrate that this scheme can be applied to communication secrecy and image encryption.
