LBKERS: A New Efficient Key Management Scheme for Wireless Sensor Networks

摘要

The framework of security communication among sensor nodes is the most important aspect and a basic research field of securing Wireless Sensor Networks. Many techniques have been developed recently to establish keys in sensor networks. Most of them are based on cluster topology. Based on the novel loop-topology, this paper proposes a new key establishment and rekeying scheme. The loop-based scheme has many advantages over cluster-based scheme. The analysis in this paper demonstrates its feasibility, efficiency and security for key establishment and maintenance in Wireless Sensor Networks.
