碩士 === 國立臺灣科技大學 === 資訊工程系 === 95 === Many applications in wireless sensor networks need precise and unitary time; therefore, how to secure time synchronization protocol is an important issue. Without key management problems, we tired to filter out incorrect data if there were compromised nodes. And then we use a new algorithm to complete this method. In this paper, some attacks and defenses have been implemented. In order to make sure that all the participated nodes can be calibrated to the same time, some of time synchronization protocols have been proposed. However, no one of them has been created with security concern. Therefore, adversary can crash the time synchronization protocol easily. On account of sensor nodes may be severely resource constrained, the traditional time synchronization and securing methods could not be applied on sensor networks. Moreover, FTSP is especially excellent and the latest protocol among them. Hence, the proposal we proposed is designed exactly for FTSP.
