New Identity-based Key Agreement Scheme for WSN
一个新的基于身份的无线传感器网络密钥协商方案

For the openness of wireless channel, establishing pairwise key between sensor nodes is the basis of the secure communication in wireless sensor networks. In most of existing IBE-based key agreement schemes, the pairwise key was established using hate pairing with high energy consuming and time consuming. In this paper, authors proposed a key agreement scheme based on BNN-IBS signature, sensors broadcast the parameters required for establishing pairwise key and compute the key using DifficHcllman key exchange technology. Compared with the IBE-based key agreement scheme, the proposed scheme has patent advantages in energy consuming and time consuming with the same security and scalabihty.
