中文摘要：

为了尽早地检测并过滤掉虚假数据以节约无线传感器网络的能量和带宽，虚假数据途中过滤策略受到了国内外学者的广泛青睐。文章综述无线传感器网络中虚假数据途中过滤技术的研究进展。总结现有途中过滤策略所能对抗的虚假数据注入的攻击模型；对现有虚假数据途中过滤技术进行分类，并分别介绍不依赖地理位置信息的途中过滤技术和依赖地理位置信息的途中过滤技术；然后，分析并比较现有途中过滤策略的属性和安全性能；最后，总结并展望虚假数据途中过滤技术的未来研究方向。

英文摘要：

In order to detect and filter out false data as early as possible to save energy and bandwidth in wireless sensor net?works,false data en-route filtering strategies are favored by the domestic and overseas scholars.With surveying recent advances infalse data en-route filtering techniques in wireless sensor networks,I summarize the models of false data injection attacks defendedby the existing en-route filtering strategies,and classify the existing en-route filtering strategies.Then the location-dependent andlocation-independent en-route filtering strategies are introduced respectively.After that,the properties and safety performance ofthe existing en-route filtering strategies are analyzed and compared.Finally,I summarize the paper and foresee the future work inthis field.
