摘要
给出了两类群密钥协商协议的效率比较,它们分别是基于口令群密钥协商协议和基于双线性对群密钥协商协议。比较的结果为对密钥协商协议的安全性分析,形式化证明及设计更有效、更安全的群密钥协商协议提供了很大的帮助。
In this paper,the compare about efficiency of two group key exchange protocols is given,in which one is password-based group key exchange protocol,the other is bilinear pairings-based on group key exchange protocol.The result for the comparison is helpful for security analysis,design and formal proof of group key exchange protocols.
