摘要：

In order to solve the problem of short period in chaotic maps, a chaotic encryption algorithm based on control word is presented. The control word switches the sequence which is actually used to encrypt. It also determines how to get some information from one of the sequences. The information combined with the value of pixel is used to be the input of the hash function SHA-1, and the output of SHA-1 acts as the disturbance to the two-dimensional maps. The control word also determines which sequence should be disturbed. The analysis of security and the experiment results show that the algorithm can improve the ability to fight against the attack and contribute to encrypting. © 2008 Binary Information Press December 2008.
