摘要: 为了分析三元对等鉴别(Trieelement Peer Authentication,TePA)机制的安全性,利用串空间模型(Strand Space Model,SSM)对TePA机制进行分析。通过分析可知,TePA机制在一些情形下虽未能达到完全的认证一致性,但仍然安全,所以TePA机制在SSM下是安全的。此外,提出针对TePA机制的2种改进措施,使得改进后的TePA机制能达到完全的认证一致性。

关键词: 三元对等鉴别, 串空间模型; 五次传递鉴别

Abstract: To analyze the security of Trielement Peer Authentication(TePA) mechanism, the TePA mechanism was analyzed based on Strand Space Model(SSM). According to the analysis, it was known that some cases of the TePA mechanism could not realize full authentication agreement, but they were still secure. Therefore, the TePA mechanism is secure in the SSM. Moreover, two improving methods for the TePA mechanism were proposed, making the improved TePA mechanism realize full authentication agreement.

Key words: Tri-element Peer Authentication(TePA), Strand Space Model(SSM), five pass authentication
