摘　　要：使用扰动算法,利用PLCM映射与Intertwining Logistic映射构造出一个三维复合混沌系统.经递归定量分析并使用尺度指数(scale index)等工具评估得出,新系统密钥空间大,抗差分攻击能力强,产生的混沌序列非周期度高、结构复杂.因此,新复合混沌系统可应用于信息安全领域.A three-dimensional composite chaotic system is constructed by using perturbed algorithm based on PLCM map and Intertwining Logistic map.Quantitative analysis and evaluation using some tools such as recursive quantitative analysis and scale index indicate that, the new system has a large key space, strong antidierential attack ability and complex structure.The chaotic sequence generated by the new composite system has a high periodicity.Therefore, the new composite chaotic system can be applied in the field of information security.

关 键 词：混沌 扰动算法 复合混沌系统 信息安全系统
