摘要: 借鉴传感器网络中基于密钥矩阵密钥对预配置方案,设计出一个应用于传感器网络的高效密钥对预配置方案:应用矩阵池的密钥预配置方案。该方案提出了矩阵池的概念,将密钥的预配置建立在多个密钥矩阵之上,节省了节点的存储空间,增强了网络的可扩展性。将加密传输机制应用到密钥的传输过程中,增强了密钥传输过程中的安全性。通过本文的分析可以看出该方案有一些优良的特性,包括两节点间能以很高的概率成功建立密钥对、对入侵有较强的鲁棒性、低通讯量。

Abstract: Using matrix-based key predistribution in distribution sensor networks for reference,this paper presents an efficient key predistribution scheme for sensor networks:key predistribution scheme using matrix pool.In this scheme we put forward the concept of matrix pool on which our key predistribution scheme is upbuilt,and encrpytion scheme is introduced into the process of key transfer.The analysis in this paper indicates that this scheme has a number of nice properties,including high probability to establish pairwise keys,tolerance of node captures,and low communication overhead.
