无线传感器网络密钥管理研究综述

Survey of key management in wireless sensor networks

由于无线传感器网络资源十分有限并采用Ad Hoc通信,所以传统网络或针对Ad Hoc网络提出的一些密钥管理机制很难在无线传感器网络中直接应用。本文介绍了几种无线传感器网络的密钥管理机制,并进行了分析比较,指出了其适用场合、不足之处、改进方法及仍需进一步研究的方向。

Wireless sensor networks(WSNS) have quiet limited resource and use Ad Hoc mechanism.These two features make both traditional key management schemes and other schemes for mobile Ad hoc networks not to apply in WSN well.The schemes of key management in WSN are introduced and analyzed.The application occasion,shortage,inproving methed and further research direction are proposed in this paper.
