Security is critically important for hierarchical wireless sensor networks. Due to the limited resources of the sensor nodes, the traditional key management schemes are not suitable for wireless sensor network. In this paper, a new key management scheme for hierarchical wireless sensor network is proposed, which would be effectively against cluster node capture by supporting multiple keying mechanisms. The security of network is independent on a single key. Compared with the LEAP protocol, our scheme has lower consumption and higher scalability.
