基于Weil配对的口令认证组密钥交换协议
Password authenticated group key exchange protocol based on Weil pairing
摘要
Abstract
Aiming at such problems as computing efficiency and security in previous group key exchange protocols, a Weil pairing-based password authenticated group key exchange protocol was presented. The ternary logic key tree was combined with Weil pairing, and the complicated exponentiation was replaced by simple point multiplication and bilinear paring operations. The construction and authentication of group key were finished after three turns of communication. The experiment results show that the algorithm reduces the height and the complexity of logic key tree and enhances the computation efficiency. In the security aspect, the protocol can resist on-line and off-line dictionary attacks, and has the forward security.关键词
