Novel Remote User Authentication Scheme Using Bilinear Pairings
This paper presents a novel password-based remote user authentication scheme using bilinear pairings by introducing the concept of private key proxy quantity. In the proposed scheme, an authorized user is allowed to login to the remote system if and only if the login request is verified. And by assigning each user his corresponding private key proxy quantity, the collusion-resistance security of the proposed scheme is enhanced. The scheme provides a flexible password change strategy and eliminates the need of the password table. In addition, the proposed scheme can efficiently resist message replaying attack, forgery attack, Masquerade attack, guessing and stolen verifier attack and collusion attack.
