基于PKI的远程网上阅卷系统安全设计

Security Design of a PKI-Based Marking System on the Internet

本文分析了利用PKI技术如何保证信息的机密性、真实性、完整性和不可否认性,介绍了PKI技术五大组成部分的功能。在此基础上,针对一个实际的基于因特网的网上阅卷系统,给出其相应的系统安全模型和设计,阐述了系统中的身份认证和数据加密机制。

This paper analyses how to ensure the confidentiality, authenticity, integrity and non-repudiation of information with the PKI technique. The five components of PKI are introduced. On this basis, we propose a practical Internet-based marking system and its security model and design, and discuss how to implement the mechanism of identity authentication and data encryption.
