A fingerprint-based user authentication protocol with one-time password for wireless sensor networks

With wireless sensor networks (WSNs) have been applied to various fields, its' security problem has become prominent for the past years. Therefore it is necessary to design a suitable security authentication protocol for WSNs. This paper proposes a fingerprint-based user authentication protocol with one-time password for WSNs. By comparing with other researcher's related work, we draw the conclusion that our improved protocol has higher security and lower overhead performance than others.
