支持身份隐藏的EAP-PSK协议改进

鉴于身份隐藏这一安全新需求,在分析EAP-PSK协议的基础上,剖析EAP-SIM和EAP-TTLS认证身份保密的特点,提出一种支持身份隐藏机制的EAP-PSK改进方案,并在复杂性上与EAP-TTLS进行了比较.结果表明,新协议具有安全、简单、可行、与原协议兼容的优点,有一定的实用价值.

Improvement of EAP-PSK Protocol Enabling Identity Privacy

Identity privacy is becoming a new security requirement of the wireless network.Recently some authentication protocols have supported this security mechanism such as EAP-SIM and EAP-TTLS.It is a pity that both of them are unsatisfactory in some aspects of solving the identity privacy.This paper describes an approach for modifying the EAP-PSK protocol to support the identity privacy mechanism.We compare the complexity of the new EAP-PSK protocol with the EAP-TTLS protocol.The result shows the new EAP-PSK protocol has the superiority in security,simplicity,feasibility and compatibility,which improve the value of practicality.
