There are no long-term credibility of the nodes, unreliable links and limitations of resources in wireless sensor networks as that in traditional networks. Based on cluster structure of WSN and identity-based encryption, this paper proposed a novel group key management scheme for WSN, which verified the correctness of group key shares, ensured the generation and rekeying of the group key and provides secure group communications. Extensive analyses and simulations show that the proposed scheme can provide a high level of security, reduce communication and storage overheads.
