无线传感器网络密钥管理问题分析

Analysis of Key Management in Wireless Sensor Networks

分析了无线传感器网络(Wireless Sensor Networks,WSN)面临的各种安全威胁,明确了其安全状况。集中对无线传感器网络安全领域中最基本的安全问题,即密钥管理进行分析,综述了该领域的研究工作,通过对现有密钥管理方案的研究和分类对比,对密钥管理问题的研究进行了总结和展望,指出了无线传感器网络中密钥管理的研究方向。

At first, we analyzed all kinds of threats faced by wireless sensor networks （WSN） and verified its security situation. Then, we concentrated on the analysis of key management problem, the fundamental security problem in the field of WSN security. We summarized the research work in the field and pointed out the advantages and disadvantages of the current key management schemas by analyzing and comparing them. In the end, we gave the research directions of key management in WSN.
