This paper examine the problem of adding security to cluster based communication protocols for homogeneous wireless sensor networks consisting of sensor nodes with severely limited resources, and propose a security solution where clusters are formed dynamically and periodically. Our solution describes re-keying function protocol for wireless sensor networks(More)
This paper describes a novel re-keying function protocol (NRFP) for wireless sensor network security. A re-keying process management system for sensor networks is designed to support in-network processing. The design of the protocol is motivated by decentralization key management for wireless sensor networks (WSNs), covering key deployment, key refreshment,(More)
This paper addressed the difficulties and challenges facing the wireless sensor networks on the battlefield cased by misdirection attack. WSNs is often vulnerable to attackerpsilas either in the routing or forwarding data and attempt to consume a lot of energy by sending a large quantity of useless packets. The main objective of the intruder is to misdirect(More)
