基于PKI-USIM的移动终端安全认证方法

摘要

随着移动通信技术的迅速发展,智能移动终端得到应用普及,大量的第三方应用也随之产生,给移动终端的信息安全带来了很大威胁。为了保护移动终端的信息安全,文中提出一种基于PKI-USIM的移动终端安全认证方法。将PKI技术与智能卡技术相结合,利用移动终端的USIM卡,实现对智能终端第三方应用的安全认证,有效提高移动终端信息的安全。 PKI-USIM对网络环境的适应、运算速度、计算能力、存储容量以及上层应用的扩展开发性能都有很大提高,PKI-USIM技术对于移动终端用户身份认证的过程具有实用性和安全性,同时也是对智能卡认证应用的一种扩展研究。%With the rapid development of mobile communication technology,intelligent mobile terminals have been applied popularly,it also leads to produce a large number of third-party applications. All of these greatly enrich people' s lives,but the information security of the mobile terminals has been threatened. In order to protect the information security of mobile terminals,propose a security authentication method of mobile terminals based on PKI-USIM in this paper. According to the realities of complex wireless network environment,com-bining the PKI technology and smart card technology,using USIM card of mobile terminals to realize intelligent terminals' authentica-tion,effectively improve the safety of the mobile terminal information. PKI-USIM has adapted to the network environment,its computing speed,computing power,storage capacity as well as the expansion capabilities of upper applications has been greatly improved. PKI-USIM technology is more practical and safer for mobile end-user' s authentication process,and it' s an extension of research on smart card two-factor authentication applications.
