%X Key management is one of the most important technologies on the security mechanism of wireless sensor network. Compared with all kinds of key management schemes, group key management is more suitable for wireless sensor network. According to the root-controlling and distributing group key management schemes, this paper proposes a novel layer-cluster key management technique and resolves specific defects of the two schemes. Furthermore, secret sharing mechanism based on (t, n) threshold cryptography realizes the secure communication among groups. The new proposal can not only meet security demands of wireless sensor network but also improve executing performance.
