A User Authentication Protocol Combined with the Trust Model,Biometrics and ECC for Wireless Sensor Networks

In this article, a new user authentication protocol using trust model, elliptic curvecryptography and biometrics for WSNs is submitted. The result of the trust modelanalysis indicates that the model can improve the model’s ability of withstandingattacks from the malicious nodes. The results of safety analysis and performanceanalysis for our proposed user authentication protocol demonstrate that thisprotocol can be flexible to all sorts of common known attacks and performssimilarly or better compared with some active user authentication protocols. It issuitable for WSNs which have a prominent request for the security and theperformance.
