A group key agreement (GKA) protocol is a mechanism to establish a cryptographic key for a group of participants, based on each onepsilas contribution, over a public network. In ad-hoc networks, the movement of the nodes may quickly change the topology resulting in the increased overhead during messaging for topology maintenance. The region-based schemes of ad-hoc networks, aim of handling topology...
A group key agreement (GKA) protocol is a mechanism to establish a cryptographic key for a group of participants, based on each one's contribution, over a public network. Security of various group-oriented applications for ad-hoc groups requires a group secret shared between all participants. In ad hoc networks, the movement of the network nodes may quickly change the topology resulting in the increased...
The adoption and widespread deployment of wireless sensor networks means that security issues are of critical concern. To date, much research has focused on the usability of these networks in a variety of environments where conventional wired networks may not be feasible. However, less emphasis was placed on the security issues of employing a sensor network and its exposure to potential threats. Due...
