中文摘要: 身份认证是网络安全的重要组成部分,当前身份认证技术通过PKI体系为服务端颁发证书实现,应用广泛,但存在对CA依赖较强、存在密钥泄露和单点失败等风险.本文基于区块链和DNSSEC技术,提出了一种新的身份认证模型,支持不依赖CA的服务端和用户端的双向身份认证,同时改进了用户证书,实现了对用户设备的授权管理,在安全性和灵活性方面具有一定优势.本文首先简要介绍了身份认证技术研究现状,随后详细描述了身份认证模型整体架构、工作流程和主要功能,最后对该模型进行了分析并提出了应用实例.

Abstract:Identity authentication is crucial for internet security, the widely adopted authentication technology relies on PKI system to issue certificates for servers, thus strongly depend on CA, which may face problems including key leakage and single point failure. Based on Blockchain and DNSSEC technology, this study puts forward a new model for identity authentication which can perform two-way authentication between server and client. In the mean time, improvements are made to user certificate for the management of trustable device of users thus enhance security and flexibility. This paper briefly summaries recent research in identity authentication technology at the beginning. Then it provides a thoroughly description of the new model, including the structure, work flow, and main functionality. At last, the paper analyzes the model and provides an example case.
