PKI网络信任模型的分析与研究

信任模型是整个网络安全体系的基础,决定了在网络上采用信任的形式与采用该形式带来的信任风险,并提供了建立和管理信任关系的框架。可见,对于信任模型的研究在网络安全中非常重要。文章着重分析了基于PKI的各类信任模型的信任机制、认证过程及其存在优缺点,指出了各类信任模型对网络信息安全产生影响的主要原因。通过总结与对比,指出了PKI信任模型的设计策略与发展趋势。

Analysis and Research on Network Trust Models Based on PKI

Trust model is the basis of the entire network security system.It determines the form of trust used in the network and the risk caused by the form.Furthermore,it provides the framework for establishing and managing the trust relations.It can clearly be seen that the study of trust model in the network security is considerably significant.This paper mainly analyses the trust mechanism,the certification process and their advantages and disadvantages about the various types of tust models based on PKI.It also points out the main reasons why trust models influence the network information security.By summing up and comparison,this paper points out the future research strategies and development trend of the trust models based on PKI.
