摘要
无线传感器网络由于其无线性质、通信和计算的局限而易受到安全威胁,传统的安全机制不适用于无线传感器网络。信任模型是无线传感器网络中的一种有效安全机制。目前,不少学者已经研究及总结大量的信任模型,但近年来对节点信任模型的研究较为匮乏。调研近年面向无线传感器网络的节点信任模型,旨在了解当前节点信任模型的研究趋势和设计思路。具体地,介绍近年较经典的节点信任模型,对比、总结当前节点信任模型的不足,并讨论无线传感器节点信任模型的未来趋势。
Due to the wireless feature and limited communication and computing capabilities,wireless sensor networks are vulnerable to security threats,and traditional security mechanisms are not applicable.The trust model is an effective security mechanism in wireless sensor networks.At present,many scholars have explored and summarized large quantities of trust models,and howeverin recent years,less researchis done on node trust models.The recent node trust model for wireless sensor networks is investigated,so as to understand the research trends and design ideas of the current node trust model.Specifically,the current relatively classic node trust modelsare introduced,thecomparison and summary on insufficiency of the node trust models also done.Finally,the future trends of wireless sensor node trust models are discussed.
