摘　　要：密钥的建立与管理是无线传感器网络安全的重要且基础的组成部分,是影响大规模应用的一个关键问题。近来,密钥建立与管理成为无线传感器网络安全领域一个活跃的研究分支。提出一种基于随机密钥预分配的无线传感器网络加密方案。该方案通过密钥互斥机制解决传统随机密钥预分配方案中点到点数据源认证问题。Key establishment and management is one of the important and fundamental building blocks of wireless sensor network,and it become a key stumbling block to the impending wide deployment of wireless sensor network. Recently,it has become an active branch of wireless sensor network security. This paper proposes an encryption scheme based on random key pre - distribution for wireless sensor network. The scheme uses mutex key strategy to solve the node - to - node data source authentication problem which exists in the traditional random key pre - distribution scheme for wireless sensor network.
