In Wireless Sensor Networks,Security is very important, especially in the networks which require high security. This paper raises a method to establish key distribution scheme, based on node layer security system, which combines with the group key distribution and identification of encryption. This method can make the two nodes carry on communication in a secure environment when identified, at the same time, communication in the safe environment between groups can also be guaranteed. The results show that the ability of resistance to attack, Sybil attack, node increases the attack, the node replication attacks can effectively be stopped. At the same time, further illustrates that the adoption of this security strategy for wireless sensor network security enhancement. Simulation results show that, the structure of security system we proposed is safe and feasible.
