改进的基于口令的三方密钥交换协议
IMPROVED PASSWORD-BASED KEY EXCHANGE PROTOCOL FOR THREE-PARTIES
摘要
Abstract
Through security analysis on an existing key exchange protocol for three-parties, we point out its pitfalls, and put forward based -on this a key exchange protocol for three-parties with perfect two-way authentication mechanism. The protocol is based on the intractability of computational Diffie-Hellman problem, it can make both parties in communication produce session key in just three rounds, and has higher computational efficiency compared with most existing protocols. The protocol is proved to be safe by the security analysis.关键词
