Wireless sensor networks are widely used in a variety of commercial and military applications. As a fundamental requirement for providing security functionality in sensor networks, key management plays an essential role in authentication and encryption. In this paper, we propose a Refined Key Link Tree (RKLT) scheme that incorporates dirty key path into the key link tree-based group key management...
Mobile ad hoc networks (MANETs) have many well-known applications in military settings as well as in emergency and rescue operations. However, a lack of infrastructure and centralized control make MANETs inherently insecure, and therefore specialized security services are needed for their deployment. Self-certification is an essential and fundamental security service in MANETs. It is needed to securely...
In this paper, we propose a new group key management scheme for wireless sensor networks in terms of the unreliable wireless channel and unsafe environment. Our proposed scheme implements node revocation through a broadcast polynomial to counteract the node compromise attack and inherits the idea of loss tolerance in LiSP to provide a reliable communication. The analysis shows that the proposed scheme...
