We propose an enhanced 3PEKE (Three-party Encrypted Key Exchange) scheme, in which both two parties/clients act as the roles upon the relationship of exchange-messages, who are employed in the traditional 3PEKE (Three-party Encrypted Key Exchange) schemes [2–5, 9, 12–17, 19, 23, 26, 27]. Our approach can improve the security of traditional 3PEKE scheme by adding digital time-stamp. By this way, we can effectively against the password guessing attack as well as replay attack.
