New low complexity key exchange and encryption protocols for wireless sensor networks clusters based on Elliptic Curve Cryptography

In this paper, we present a key exchange protocol for clustered wireless sensor networks based on Elliptic Curve Cryptography, which enables secure key distribution and authentication mechanism. The proposed protocol is optimized for clustered sensor networks and is efficient in terms of complexity, number of message exchange, computation, and storage requirements with optimized security benefits for clustered environment.
