| 摘 要： | 针对现有传感器网络密钥管理方案存在的网络连通度低、抗俘获性差、节点能耗高等问题，该文提出一种基于(q,l)门限秘密共享的密钥共享模型，采用虚拟簇头共享密钥，物理簇头重构密钥的方式完成簇头与簇成员的密钥协商。该模型实现了簇成员能耗最低、抗俘获性最优的目标，同时门限参数l和q能够调节簇头的抗俘获性、容错性和高效性。理论分析与实验证明，与传统的概率型方案相比，该模型有效地提高了节点抗俘获性和网络连通度，并降低了节点能耗。

| Abstract: | Most traditional probabilistic key management schemes of wireless sensor networks have disadvantages of low connectivity,poor resiliency against node capture,and high energy-consumption.A key sharing model is proposed based on(,)-threshold secret sharing.In this model,a key is divided into shadows to be shared by virtual cluster heads and re-constructed by the physical cluster head.For tiny cluster member nodes,this model is optimized in improving their resilience against node capture attacks and saving the... |
