摘要：
An improved image encryption algorithm based on chaotic logistic map is designed. First, after two initial values of Logistic chaotic map are pretreated, two of the modified initial values are obtained, according to which two chaotic sequences are generated. Next, two chaotic sequences are operated by cos(-1) function. Last, image is encrypted combining the method of the gray value substituting. Results and analysis of simulation show that the proposed scheme has higher security.
