A Provably-Secure ECC-Based Authentication Scheme for Wireless Sensor Networks

A smart-card-based user authentication scheme for wireless sensor networks (in short, a SUA-WSN scheme) is designed to restrict access to the sensor data only to users who are in possession of both a smart card and the corresponding password.While a significant number of SUA-WSN schemes have been suggested in recent years, their intended security properties lack formal definitions and proofs in a widely-accepted model.One consequence is that SUA-WSN schemes insecure against various attacks have proliferated.In this paper, we devise a security model for the analysis of jeff rosenstock buffalo SUA-WSN schemes by extending the widely-accepted model of Bellare, Pointcheval and Rogaway (2000).

Our model provides formal definitions of authenticated key exchange and user anonymity while capturing side-channel attacks, as well as other common attacks.We also propose a new SUA-WSN scheme based on elliptic curve cryptography (ECC), and hindigyanvishv.com prove its security properties in our extended model.To the best of our knowledge, our proposed scheme is the first SUA-WSN scheme that provably achieves both authenticated key exchange and user anonymity.Our scheme is also computationally competitive with other ECC-based (non-provably secure) schemes.
