摘要
针对通信的安全可靠问题，探讨了利用混沌进行保密通信的可行性．提出了一个新的三维混沌系统，该系统含有三个参数，每一个方程合有一个非线性乘积项，运用Multisim软件对该混沌系统进行了仿真，并设计了相应的实现电路．试验结果与仿真结果完全相符，验证了系统的混沌行为和可实现性．所设计的电路参数与系统参数一一对应，可调参数少，实现容易．为混沌通信、信息加密等领域提供了新的混沌信号源．
Considering the safe and reliable problem of communication, the feasibility of adopting chaos for secure communication is researched. In this paper a new three-dimensional chaotic system is presented, each equation contains a single cross-product term and a system parameter, and the circuit of the system was given. The circuit of a new chaotic system realized is simulated using Muhisin and the results were found to be identical to the numerical simulations of Matlab. System parameters are in accord with the parameters of the circuit and it is easy to realize for its few adjustable parameters. This system can be used as a new chaotic supply oscillator in cryptography and other correlative fields.
