A scalable grouping random key predistribution scheme for large scale distributed sensor networks

Abstract

[[abstract]]The security issue in a distributed sensor network (DSN) has been drawing considerable research attention in recent years. Key management, a basic security service, becomes the core design for various security services, such as encryption and authentication. This paper proposes a scalable grouping random key predistribution scheme which divides all nodes into several groups and uses the oneway Junction to generate group-to-group pairwise keys to increase the connectivity of each key and to enlarge the maximum supportable network size.[[conferencetype]]國際[[conferencedate]]20050704~20050707[[iscallforpapers]]Y[[conferencelocation]]Sydney, Australi
