Identity based authentication protocol for wireless sensor networks

Abstract

In this work, a novel identity based authentication protocol for sensor networks is proposed, involving bilinear pairings over an elliptic curve point group, and message authentication codes, as main underlying components. This protocol is capable to perform authentication for both nodes and messages, guarantying an acceptable level of scalability for network size and nodes’ diversity. Herein, the proposed protocol is described in depth, as well the costs estimations for its operation on a WSN.
