Key-management is extremely important for security of the whole wireless sensor networks,considering problems existing in some key-management schemes and applications of hierachical routing protocols,a new key-management scheme for wireless sensor networks is proposed.The base station distributes key-pools for every cluster according to clustering information,gateway nodes are used for secure inter-cluster communication.This scheme is useful for security system of large scale sensor networks.
