摘　　要：研究了用Petri网对密码系统建模和分析 ,用在系统可编程逻辑器件实现Petri网的方法 ,这种密码系统的设计方法简单、直观 由于Petri能够对复杂系统进行建模和分析 ,因此 ,采用这一方法能够十分容易地构造出复杂的密码系统 ,并确保系统的安全、可靠 文中给出了几种密码系统的Petri网模型 。A method of modeling and analysing cryptography with Petri nets and implementing the Petri net with in system programmable logic device is introduced. This method is simple and straight foreward. Due to the fact that Petri nets can be used for modeling and analysis of complex systems, it is very convenient to establish a complex, safe and reliable cryptography by adopting the method. Some models of cryptography and an example of hardware implementation are presented.
