摘　　要：由于传感器节点部署的随机性、以及网络规模迥异的特点,已有的对偶密钥建立机制可能使得网络中出现若干个孤立的连通集团。在提出基于多点认证的信任模型上,分析了可能使得集团互联的一类关键节点的性质。仿真结果表明,通过关键节点间的对偶密钥建立协议,与传统的建立过程相比,在取得相近抗妥协性能的前提下,能够有效地实现孤立集团间的互联。Available mechanisms on pairwise key establishment will make possible a number of isolated connected components in sensor networks,due to random deployment of sensor nodes and dramatic degree of network scale.Based on muhi-nodes authentication trust model,a kind of essential nodes that will make components interconnection is analyzed.Also pairwise key establishment protocol for those, nodes is presented.Compared with widely accepted pairwise key establishment,figures show that the presented protocol can achieve interconnection of components effectively,with little loss on resilience of sensor nodes in the network.
