A Remote User Authentication Scheme with Smart Cards Using Bilinear Pairings

The remote user authentication schemes with smart cards using bilinear pairings are discussed. As the scheme proposed by Giri et al is vulnerable to masquerade attack in the case that the information stored in the smart card is stolen, a new remote user authentication scheme with smart cards using bilinear pairings is proposed. The proposed scheme is performed lower computation cost since in login phase only the addition in the group is needed. The scheme provides better security because it can withstand replay attack, off-line attack and masquerade attack.
