In this paper, the authors improve an efficient and complete remote user authentication scheme and propose an adaptive timestamp-nonce based authentication scheme using portable storage devices. Compared with other smart card-based, timestamp-based and nonce-based schemes, their scheme achieves more functionality. The new importance merits are: an adaptive timestamp-nonce structure is proposed; portable device stores authentication data not only smart card; all transactions through non-secure channel, especially in the registration phase and batch of portable storage devices is issued.
