摘要
文章针对网络安全保密系统的安全需求和运行特性,引入Petri网理论指导网络安全保密系统的可靠性建模与分析过程。首先详细描述了运用随机Petri网对网络安全保密系统进行可靠性建模与分析的具体方法和过程;然后给出一个实例,对系统的保密性服务子系统进行建模,并分析了该子系统在安全运行状态下的可靠性。通过对可靠性建模分析方法的应用,不仅实现了系统方案设计阶段可靠性的可评估性,而且提高了系统后期开发过程的可操作性。
In accordance with the security requirement and running characteristic of Network Security Secret System, the theory of Petri Net is introduced to instruct the process of NSSS reliability modeling and analysis. This paper first describes in detail the method and process for using SPN to model and analyze the reliability of NSSS; then presents an example~＂thus to model the secrecy service subsystem, and analyze the reliability of the subsystem under the security running state. Applying the method for reliability modelling, the system reliability appraisal in the stage of project design is realized while the operability of later-stage development process is improved.
