几种身份认证技术的比较及其发展方向

Developing trend comparison of several authentication techniques

身份认证是保障网络安全的关键,目前主要的身份认证技术包括:基于口令的认证技术、基于智能卡的技术、基于密码的技术及基于生物特征的技术。本文通过对这几种主要的身份认证技术的比较,分析了它们的各自优势与缺陷,并提出了一些改进意见,认为身份认证技术将在多技术的融合、分布式认证及认证的标准化方面有进一步的发展。

Authentication is critical to the network security. The current primary authentication is based on such techniques as password, smart card, cryptography and biology character. In this paper, some kinds of predominant authentication techniques are introduced, and the advantages, defects and improvements of these techniques are analyzed. In our view, the authentication techniques will probably develop towards the multi-techniques incorporation, distributed authentication and normalization of authentication.
