New Identity-based Key Agreement Scheme for WSN
WU Jian-qiang · 2011
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 Tate 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 Diffie-Hellman 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 scalability.
