| 摘 要： | 针对目前混沌加密方法系统易识别和序列在其值域内分布不均匀的缺陷，提出了一种先对图像进行二维猫映射置乱预处理，然后叠加均匀分布的复合混沌序列对图像进行加密的方法，并且分析了该方法的加密效果、抗统计攻击及系统识别攻击能力.

| Abstract: | In allusion to the bugs of some chaotic cryptography that the recognize is easy to recognize and the sequence's distributing is asymmetry,a new data cryptology is brought forward which uses the Arnold cat map pretreatment then XOR the uniform composite choatic sequence.The encrypted effect and the capability of resisting to the statistical attack and system recognition attack is analyzed. |

| Keywords: | uniform composite choatic-sequence image cryptography statistical analysis |
