摘　　要：由于Lorenz,Duffing等一些混沌算法结构过于简单并且参数数量较少,应用在信息加密中容易被破译.将Lorenz与Duffing混沌算法相融合,产生一种新的多参数、结构复杂的六维混沌算法.将该混沌算法结合Arnold映射应用于彩色图像加密领域,仿真结果表明该混沌算法加密效果良好.Some of the chaotic algorithms as of the Lorenz, Dulling and so on are too simple in structure and have inadequate parameters, so applied to information encryption is easy to be decrypted. By mixing the Lorenz chaotic algorithm with the Duffing chaotic algorithm, a new multi-- parameter six-- dimensional chaotic algorithm with a more complex structure is proposed in this paper. Combined with Arnold mapping applied in color image encryption area , the simulation results show that the new algorithm thus created is very effective.
