In such kind of Internet based applications, access must be secure and authentication takes a vital role to avoid malicious use of the system. This kind of security has been provided by several previously proposed algorithms based on RSA digital signature cryptography. However, the computational time for performing encryption and decryption operations in the past literatures is very high. In this paper, we propose an anonymous authentication scheme which potentially reduces the overall computation time needed for verifying the legitimacy of the users. Comparing with previous anonymous authentication schemes, our proposed scheme provides more security and it is effective in terms of computation cost.
