Wireless Sensor Network and security is innovative
research area for some research aspirants. Time synchronization
is the delicate 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, we have shown necessity 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. Our scheme removes different
threats on synchronization and makes system more robust. We
have provided centralized control in distributed wireless sensor
network which reduces complexity of real time application of
wireless sensor network.

Mostly the techniques for secure time synchronization
send different synchronization messages, in some
techniques static pair wise key-based cryptographic
mechanisms is used in order to provide secure
synchronization. Some techniques uses GPS, sensor nodes
have resource limitation, also data transmission cost is
significant in wireless sensor networks. We tried to
overcome such problem and provided secure
synchronization in WSNs. We have focused on reducing
the communication overhead in the network so that the
energy requirement reduces and that energy can be use for
security purpose.
