An ID-Based Pairwise Key Predistribution Scheme for Wireless Sensor Networks
Liping Zhang, Yi Wang · 2010
Providing a suitable key establishment scheme in wireless sensor networks is challenging due to all the characteristics of these networks, such as limitations of power, computation capability and storage resources. Several key management schemes were proposed, but most of them are not resilient to nodes capture. In order to improve the resilience to nodes compromising, in this paper we propose an ID-based pairwise key predistribution scheme that is based on a hierarchical grid model for wireless sensor networks. In the proposed scheme, the symmetric matrix is employed by hierarchical grid model to establish pairwise key. So it can achieve high resilience to nodes compromising.
