Dual Trust Secure protocol for cluster-based wireless sensor networks

In addressing the unique security challenges faced by wireless sensor networks, this paper proposes a novel, two-level trust-based scheme. The solution is described on top of a well-known, cluster-based protocol, LEACH (Low Energy Adaptive Clustering Hierarchy), and is named DTSLEACH (Dual-Trust Secure LEACH). It includes authentication, confidentiality, integrity, and trust mechanisms. Performance evaluation shows that, compared with two other existing protocols, DTSLEACH provides strong performance in security, energy and memory efficiencies, as well as network throughput.
