基于矩阵的无线传感器网络密钥预分配
Key pre-distribution scheme for wireless sensor network using matrix deployed knowledge
摘要
Abstract
In order to enhance the probability of common keys in neighbor nodes,reduce wireless sensor networks resource cost and further enhance connectivity of wireless sensor networks (WSNs),this paper proposed a key management scheme using matrix deployment and communication key for wireless sensor networks.It used way of 3 × 3 matrix to distribute the keys so as to the neighbor nodes have q common keys.In square grid using matrix deployment could enhance the threshold of common keys and reduce redundancy keys in each of node.Theoretic studies and figures of simulation show that the proposed scheme not only provides better performance in connectivity and security,but also obtains up to 100％ reduction in the number keys.关键词
