Wireless sensor network has many applications for target tracking and locating. By establishing a tracking cluster, we propose a Tracking Cluster Rekeying Protocol (TCRP), in which sensors are able to locate moving objects in a monitored area. By dynamically forming a tracking cluster around the target, TCRP save network traffic. We also present a novel session key scheme for data exchange, and pre-established encrypt links are used to guarantee the system security. We then show that TCRP can track fast moving target efficiently and securely.
