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

Blog Article

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 Hanging Organiser 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 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 Incubators on elliptic curve cryptography (ECC), and 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.
