Research of pairwise key establishment protocol in sensor networks
传感器网络中对偶密钥建立协议研究

A number of isolated key-sharing component would be available in wireless sensor networks, due to random deployment of sensor nodes. In order to solve this problem, multi-nodes trust model based on trust relationship transfer was presented, along with the corresponding results key establishment protocol based on authentication in trust field. Simulation show that the presented protocol can achieve interconnection of components effectively, as well as nice performance on resilience of sensor nodes in the network. Thus, the security and effectiveness of the protocol are verified.
