Wireless sensor network is innovative research area for some research scholars. Time synchronization is the vital part in the Wireless Sensor Network (WSN) due to the requirement of coordination between sensor nodes. Also security plays important role to avoid attacks on time synchronization. In this paper, the authors have shown need of secure time synchronization, problem related with synchronization, how secure time synchronization can be achieved on sink node with reduced energy consumption, quickness in effective manner.
