基于PKI的网络信息安全模型的研究与设计

Internet/Intranet的引入为企业实现信息化,提供了一个快捷、高效、方便的网络环境,但网络信息安全问题越来越突出.PKI为基于网络的安全应用提供了一个真正可靠、稳定、安全的平台.通过对当前网络存在的安全性问题分析,首先探讨PKI/CA的体系结构并对其进行了改进,提出了一种基于PKI的可靠的网络信息安全模型,并按照此模型架构企业的PKI应用体系,并结合企业网上电子商务实例进行分析和讨论.

Study and design of network information secure model based on PKI technology

The Internet/Intranet emergence provided for the business enterprise a fast, efficiently, convenient network environment. But the security problem of network information system is more and more outstanding. PKI provide a real credible, steady, secure platform for secrecy application based on network. Firstly, the security problem of network and the architecture of PKI/CA system are discussed. The further improvement is made. A network information secure model based on PKI technology is designed and the safe system on network according to this model is set up. Finally, a practical instance ore-commerce is analyzed in detail.
