On Pairwise Key Establishment Protocol between Sensor Nodes Based on Trust Field Authentication

From the viewpoint of protocol security,the pairwise key establishment of wireless sensor networks(WSNs) is analyzed.Authentication model in trust field is presented,and the corresponding pairwise key establishment protocol is proposed.The simulation results show that,compared with traditional pairwise key path establishment,the presented protocol can achieve similar performance on anti-compromise and can effectively interconnect the isolated components.
