| 摘 要： | 针对混沌同步的混沌通信方案存在的安全问题,提出了一种基于猫映射变换的改进方案.利用回归映射破解方法和功耗分析破解方法,攻击者可在混沌系统参数未知的情况下破解混沌信号.在所提出的改进方案中,发送端使用猫映射变换将混沌序列置乱,利用置乱后的混沌序列作为载波进行通信;在接收端进行猫映射逆变换恢复出原始混沌序列,进而实现混沌同步,完成解调.所提出的改进方案简单、易于实现,能够有效地抵抗回归映射和功耗分析的破解.

| Abstract: | An enhanced scheme based on cat map was proposed to solve the security problem in the chaotic communication with synchronized chaos.For the existing chaotic communication scheme,the chaotic signal can be broken by return map and power analysis even if the parameters of a chaotic system are unknown.In the proposed scheme,the cat map is used at the sender to disorder the chaotic sequence and the disordered one is used as the carrier in the secure communication.While at the receiver,the original chaotic sequen... |
