A dynamic and scalable security framework for ad-hoc sensor network

Ad-hoc network is a well known autonomous mobile system connected by distributed wireless nodes, in which each one is free to move or join and without any fixed infrastructure. Providing a comprehensive security model for Ad-hoc network is a bit hard, although some specific solutions have been proposed recently. In this paper, we firstly introduce a threshold signature approach and a distributed slave certificate based trust membership management scheme, and then present a novel security framework, which is effectively integrated with forenamed two methods and is fully dynamic and scalable for member-sporadic Ad-hoc network groups. Finally, the model analysis and a conclusion is described.
