Abstract

In 2006, Das et al. proposed a remote user authentication scheme using the properties of bilinear pairings. The current paper, however, demonstrates that Das et al.'s scheme is still vulnerable to an impersonation attack and an off-line password guessing attack. Furthermore, we present an improved authentication scheme based on bilinear computational Diffie-Hellman problem and one-way hash function to the schemes, in order to isolate such problems.
