In earlier, two smart card based password authentication key exchange protocols were proposed by lee et al. and Hwang et al. respectively. But neither of them achieves two factor authentication fully since they would become complete insecure once one factor is broken. To overcome these two factor authentication problem in Password Authentication Key Exchange protocol (PAKE) proposed a new efficient PAKE protocol with the concept of One Time Private Key (OTPK) concept, which achieves fully two factor authentications and provide forward security of session keys.
