改进的基于口令的群密钥协商协议
Improved Password-based Group Key Agreement Protocol
摘要
Abstract
Group key agreement protocol is an important mechanism to ensure the security of subsequent communication. This paper researches a password-based Group Key Agreement(GKA) protocol proposed by Byun and Lee and finds that this protocol is vulnerable to undetectable on-line dictionary attacks. Based on this finding, it improves this protocol and presents a new GKA protocol. Security analysis shows that the protocol is resistant to the attacks available for password-based GKA protocols.关键词
