Most three-party authentication key exchange protocols are not security enough,and can not resist the undetectable online dictionary attack.Aiming at these problems,this paper proposes a three-party authentication key exchange protocol based on password.It analyses the vulnerability of the simple three-party authentication key exchange protocol,and proposes an improved security new protocol.Analysis result shows that,compared with the simple 3PAKE and the other protocols,the execution efficiency on calculation of the new protocol is better.
