云计算中几种身份认证技术的比较分析

身份认证解决云计算中信息安全威胁的重要手段之一。身份认证的本质是根据用户所知道的东西、拥有的东西或所具有的生物特征来确认用户身份。现有的使用密码技术的身份认证技术主要由三种:基于公钥基础设施(PKI)的、基于组合公钥(CPK)的、基于身份加密(IBE)的。文章通过几种身份认证技术的原理以及特点的对比,分析出各自的优势。

Comparative analysis of several authentication technologies in cloud computing

Identity authentication is one of the important means of information to solve security threats in cloud computing. The nature of Identity authentication is based on user what you know, have or have biological characteristics to identify the user identity. The use of existing password authentication technology is mainly composed of three types: based on public key infrastructure (PKI), based on combined public key (CPK), identity based encryption (IBE). In this paper, several kinds of identity authentication technology principle and characteristics of contrast, analysis of their advantages.
