摘　　要：为了提高邻居节点建立共享密钥的概率,减少无线传感器网络资源的消耗,从而进一步提高无线传感器网络中的连通性,提出了一种基于矩阵的无线传感器网络的随机密钥部署方案。该方案在无线传感器的目标划分区域中采用3×3矩阵的方式进行密钥预分配,使邻居节点共享直接密钥的个数为q,提高了节点间共享密钥的阈值,减少了节点存储冗余密钥的数量。数据分析和仿真结果表明,该方案不但在存储密钥数量和安全性方面有较好的性能,而且连通率为100%。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 com- mon 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.
