In recent years, wireless sensor network is booming because of the mature of wireless network and its variety in applications. But secure communication is a very important requirement in wireless sensor networks, message encryption techniques, such as DES and AES, are widely used to achieve the confidentiality of transmitted data. And, how to share the same session key between the sensor nodes becomes the major problem. In this paper, based on the network structure of clustering, a security and efficient key management scheme for wireless sensor networks is proposed by using node-ID and bilinear pairings. Comparing with the previous key management schemes for wireless sensor networks, this scheme improves network connections, storage, communication burden and ability of resistance against node capture.
