Abstract
Hardware smart tokens are gaining popularity in strong online remote authentication. Das introduced a dynamic ID-based remote user authentication scheme with one-way hash function using the smart card. Lee, Hwang, Jian and others made alternative dynamic ID-based authentication schemes with smart card. This paper proposes an improved dynamic ID-based authentication scheme based on Jian's scheme by Adding public key cryptographic layer and using hardware smart token. Our proposed scheme will be more flexible because the using of dynamic ID-based authentication scheme with hardware token makes it easier and more secure.
