摘　　要：提出了一种新的MDA置乱信息加密方法。结合递归运算,设计了基于MDA置换的信息加密、解密算法。首先由随机函数生成得到任意的不相等的混沌序列,以此序列作镜像变换后对信息进行置换而得到加密文件。解密算法是加密算法的逆过程。实验结果表明,该算法能够得到令人满意的结果。A new method based on disorder information secret-code is proposed in this paper. Combined with recursion operation, an encrypting and decrypting based on MDA disorder information are designed. A random unlikeness chaotic sequence is created with random function. Mirror image transforms with this chaotic sequence, then the information is transformed to secret-code files by this sequence. The decrypting operation is the reverse of encrypting. The results indicate that the proposed algorithm can get satisfying effect. The characteristics of algorithm are summarized and the aspects of the subsequent work are prospected.
