无线传感器网络中的信任管理研究现状

Research on Security of Trust Management in Sensor Networks

无线传感器网络是一种新型的无基础设施的无线网络,具有与传统网络不同的特点,且与应用高度相关。传统网络中的安全机制不能有效应用于无线传感器网络,需要建立信任管理模型来保证网络的安全性。本文首先介绍了无线传感器网络的特点和建立信任管理模型需要考虑的关键问题,然后分析了一些较为典型的信任管理模型。最后,总结了无线传感器网络中信任管理的研究现状以及未来的发展方向。

Wireless sensor networks are new facilities -baseless networks which are different from traditional networks and highly dependent on applications, so traditional security mechanisms cannot be applied effi- ciently to them. Therefore trust management schemes are needed to secure the networks. After describing the characteristics of wireless sensor networks and the key problems, several typical trust models are introduced. Finally, the current status of study and the future directions of trust management in wireless sensor networks are summarized.
