Specific to treatment the issues about vulnerable nodes leading to the key leakage in the Wireless Sensor Network,this paper proposes a routing scheme of key management in Wireless Sensor Network based on the LEACH. The scheme is based on LEACH protocol,and brings in the management node which is responsible for predistributing the keys,setting up the key pairs and redistributing the keys. Combining with the generating of key pool,it utilizes Hash function and ternary polynomial for the key encryption and building the key pairs,and guarantees communication and security in Wireless Sensor Network. The simulation results show that the scheme is improving the invulnerability effectively and prolonging the lifetime in Wireless Sensor Network.
