Tripartite Key Agreement Protocol Based on Double Factor Authentication
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.
