| 摘 要： | 提出了一种用于无线传感器网络中的改进的矩阵密钥预分配的方法。该方案能够支持网络拓扑结构的变化，并且能动态管理密钥信息，从而解决了密钥泄漏等问题。同时基于分簇结构，该方案能减少普通传感器节点的通信和计算开销，节约存储空间，从而解决普通节点资源受限的问题。仿真结果显示，与已有的一些密钥方案相比，该方案提高了网络的安全性,减小了存储空间。

| Abstract: | This paper proposed an improved matrix key-distribution scheme for wireless sensor networks. This scheme can delete and update key information with the network topology changes to avoid key information to be revealed. Also, based on the clustered structure, this scheme can reduce communication,computation and key storage overhead, which can solve the problem that each sensor node has limited resource. Comparison and simulation results show that the proposed scheme has higher network security and lower key s... |
