摘要
提出一种基于混沌的序列密码生成方法，该方法通过随机改变混沌映射的参数来提高混沌的复杂性。同时在有限精度实现时，通过引入扰动序列使得输出的混沌序列具有良好的自相关性、均匀分布特性和随机统计特性。理论研究和模拟结果表明，该混沌序列加密方法具有较好的保密性，并且便于软硬件实现。
In this paper, a sequence encryption method based on chaos is proposed. This method improves the complexity of chaos by randomly changing the parameter of discrete chaotic map. At the same time, by introducing proper perturbation, the chaotic sequence has the good self-correlation property, uniform distribution property and random statistical property under the finite precision in real application.The result of our study shows that this method is fine in security and can be realized easily in software or hardware.
