摘要
提出了一个七维四次超混沌系统,通过Lyapunov指数计算验证了系统的混沌特性,并给出了系统的硬件实现电路。系统的Matlab仿真波形与所设计电路的Multisim仿真波形完全一致,证明了系统的可实现性。并且利用该混沌信号源实现信号加密,把混沌信号的迭代的次数以及对各个混沌信号采用不同的放大或缩小倍数设置为密钥,提高了信息传递的可靠性和安全性。
A seven-dimensional four hyperchaos system is put forward,through the Lyapunov index calculation to verify the chaotic characteristic of the system,and to give the system realization of hardware circuit.The system results of the design of Matlab simulation and the circuit results of Multisim simulation are completely consistent,it proves that the system can be realized.By using the chaotic signal source encryption,it can put the chaotic signal iterative times and to each of chaotic signal using different larger or smaller set for multiple keys,then improves the reliability of the information transmission and security.
