Efficient Key Management Scheme in Wireless Sensor Networks

Abstract

Because of the constraint of sensor nodes in energy powering, storage capacity, and computing power, in order to use less resource and improve the security of WSNs, we propose a novel key management scheme which relies on the remainder of small integer and the connected graph theory.The key management scheme improves the resiliency of WSNs to sensor nodes compromise, and minimizes the storage usage as well as communication load when establishing common keys.The major parts of the scheme include id_key generation and distribution, id_key discovery and common key establishment, secure path establishment, and incremental addition of sensor nodes.Finally, we will analyze the scheme in different aspects.
