Novel Protocol for Secure Clock-synchronization in Dynamic Wireless Sensor Networks
Baohua Zhao · Journal of Chinese Computer Systems · 2008
A novel scheme called Dynamic Secure Clock-synchronization(DSCS) is proposed for wireless sensor networks(WSN).As a result,the attacks from the outside malicious nodes are blocked due to a local broadcast authentication scheme while the attacks from the inside compromised nodes are prevented by the redundant synchronization messages.The two solutions make DSCS secure and resilient.DSCS is fit for both dynamic and static networks.The simulation results present the great efficiency of DSCS.
