A Novel Remote User Authentication Scheme from Bilinear Pairings Via Internet

Recently, Manik et al. proposed a remote user authentication scheme using bilinear pairings, in which the user can login to a remote system with his own smart card. Some security flaws and improvements of Manik et al.'s scheme were investigated and proposed by researchers. One of the most comprehensive studies of this type was conducted by Fang and Huang in the same year. Fang and Huang showed types of potential attacks on Manik et al.'s scheme and further proposed an improved scheme. In this paper, we demonstrated that both Manik et al.'s and the Fang-Huang schemes are vulnerable to a range of attacks to show the claimed security requirements cannot be achieved. Therefore, we proposed a novel remote user authentication scheme from bilinear pairings via Internet, which can withstand the types of attacks that would threaten the previous schemes. The proposed scheme not only enhances the security of the remote user authentication scheme but also achieves high levels of performance.
