摘要
为了设计新的伪随机序列发生器,以便产生计算机、通信和密码系统中所需的伪随机序列,构造了一个新的混沌系统,该文系统的一些基本动力学特性进行了理论分析,并以新构造的混沌系统作为随机信号源,基于FPGA设计了一个混沌伪随机序列发生器并进行了实验验证。这种设计方法可应用于以FPGA为平台的混沌通信和密码系统的设计之中。
In order to design novel pseudo random generators and generate pseudo random sequences for com- puters, communications and cryptosystem, this paper constructs a novel chaotic system. Some basic dynamics of this system are analyzed theoretically. A chaotic pseudo random generator is designed and experimentally confirmed based on FPGA, taking the proposed chaotic system as a random signal seed. The proposed method in this paper can be used in chaotic communication and cryptosystem that take the FPGA as the platform.
