Design of simulation experimental teaching platform for modular multi-chaos secure communication system

将混沌保密通信理论用于实验教学,设计了一种模块化多混沌保密通信系统仿真实验教学平台。该平台包括混沌驱动系统模块、混沌响应系统模块、加密模块和解密模块。以Lorenz混沌系统为例,根据驱动-响应同步理论构造出Lorenz混沌驱动系统模块及其对应的混沌响应系统模块,然后构造加密模块和电路模块。用Multisim仿真软件对系统电路进行仿真,仿真结果验证了整个系统电路设计的正确性。

In order to apply secure communication based on chaos theory to experimental teaching,a simulation teaching platform is designed for modular multi-chaos secure communication system.The platform includes the following four parts：chaotic driving system module,chaotic response system module,encryption module and decryption module.The design takes the Lorenz chaotic system as an example.Firstly,according to the driveresponse method,Lorenz chaotic driving system circuit module and Lorenz chaotic response system circuit module are constructed,then the encryption circuit module and decryption circuit module are constructed.Multisim simulation software is used to verify the correctness of the entire system.
