摘　　要：从无线传感器网络的安全分析入手,在分类描述无线传感器网络密钥管理方案并分析其优缺点的基础上,结合树型密钥管理结构,提出了一种新的分簇式密钥管理方案.因不同的消息类型有不同的安全需求,该方案建立了4种通信密钥类型:个体密钥,点对密钥,簇密钥和组密钥.其中点对密钥的建立采用了基于临时认证密钥的方法,加强了对节点的身份认证功能,提高了方案的安全性.Research on key management is always a hot spot in Wireless Sensor Network. Starting with the analysis of security in Wireless Sensor Network, this paper describes several types of security key managements schemes by comparing their advantages and disadvantages. Based on the discussion, it presents a new kind of clustered key management scheme. Because of different requests in security for different kinds of messages, there are four kinds of keys for communication in this scheme： personal key, pair-wise key, cluster key and group key. Especially the construction of pair-wise key, which is based on temporary authentication key, strengthens the function of identity authentication to nodes and improves the efficiency of security.
