Abstract
This paper analzsed the security of a cipher based on a map of the logistic chaos sequence. However, the information leakage that the first several chaotic states generated by this encryption system were not sensitive to the change of the low order of initial input, makes the encryption system can not to resist the divide-and- conquer attacks, under the chosen plaintexts condition. The improvement, which making the distribution of coincidence degree of the keys tends to randomize, can effectively resist the attacks.关键词
