摘要
针对三方密钥协议中的在线不可检测词典攻击、假冒攻击问题，基于用户身份、口令，结合单向陷门函数，提出了基于双因子认证的三方密钥协商协议。该协议具有前向安全，能抵抗在线不可检测词典攻击、假冒攻击。密钥协商过程中使用了非对称加密、单向陷门函数，有效保证了通信双方的安全性。
Abstract
For the online not detect dictionary attack,counterfeit attack problem in the three key agreement. three key agreement protocol is put forward based on double factor authentication,with the user identity and password,combination with one-way trapdoor function.The proposed protocol provides forward security,can resist online not detection dictionary attacks,fake attacks. Key agreement using asymmetric encryption,one-way trapdoor function,effectively ensures the safety of the communication on both sides.
