To avoid the impersonation attack, an efficient and secure key issuing protocol based on identity-password pair is proposed, in which an additional identity-password pair issued by KGC and KPAs is used to authenticate a user’s identity. In this protocol we use a simple blinding technique to eliminate the of secure channel and multiple authorities approach to avoid the key escrow problem. Our protocol solves the key-escrow problem successfully and saves at least 4n pairing and 2n Hash operations in comparison to Lee B et al’s protocol.
