摘要 为解决当前无线传感器网络在目标定位与跟踪等领域的安全问题,提出了一种建立在自动跟踪簇基础上的动态簇密钥更新算法MCDGR。传感器节点根据事先设定的敏感度阈值可发现并定位在被监视区域中移动的物体,在被跟踪对象周围组织一定范围内的节点建立跟踪簇,并使它在逻辑上跟随目标移动,从而建立起分层的路由拓扑结构。通过簇首节点对感测数据进行数据融合后,向sink节点汇报目标位置。同时通过引入以q合成、多路增强与单向密钥序列技术为基础的随机密钥预分配协议,可以在大规模传感器跟踪网络的使用中同时达到提高跟踪精度、安全性和降低能耗的目的。 To enhancing the wireless sensor network＇s security in target tracking and locating application, a tracking duster based mobile cluster distributed group rekeying protocol（MCDGR） was proposed. Based on the given sensitivity, sensors can locate the moving object in the monitored area and form a tracking duster around it. This tracking cluster can follow the target logically, process data on the target and report to the sink node, and thus achieve the tracking function. Based on the multi-path reinforcement scheme, q-composition scheme and one-way cryptographic hash function, random key predistribution algorithm（RKP） was introduced to guarantee a high accuracy and security and a low energy consumption on the same time in large-scale sensor network.
