An Identity-Based One-Time Password Scheme with Anonymous Authentication

Password authentication is one of the simplest and the most convenient authentication mechanisms over insecure networks. One-time password authentication which uses dynamic password helps to enhance the security of password. In this paper, we suggest a new one-time password scheme using the smart card based on the bilinear pairings. By generating temporary identity, our scheme can provide anonymity in authentication process to protect the userpsilas privacy. Based on the Computational Diffie-Hellman Problem, we show that the proposed scheme is secure against forgery attack and ID attack under the random oracle model.
