摘　　要：提出了一种基于logistic和Henon的双混沌映射加密算法,通过级联一维混沌系统和二维混沌系统,利用复合迭代所产生的混沌序列对明文进行加密,开发了算法的模拟实验平台。实验结果表明,与传统DES和基于Lorenz的加密相比,该算法在加密强度和运算效率上达到了较好的均衡。The paper presented an encryption algorithm of double chaotic map based on logistic and Henon. By cascading one- dimensional chaos system and two-dimensional chaos system, used chaotic series produced by composite reeonstruction in en- cryption for plain text. It exploited the simulated experiment platform of the algorithm. Compared with conventional DES encryp- tion and encryption algorithm based on Lorenz, the simulation shows that the new algorithm has good performance in balancing encryption intension and operation efficiency.
