【摘要】 抵制节点捕获弹性是传感器网络密钥预分配安全性的主要指标之一。在给出传感器网络攻击模型和抵制节点捕获弹性定义的基础上,深入分析和对比基本随机密钥预分配、Q-composite随机密钥预分配以及随机密钥预分配加强模式的弹性。研究结果表明密钥池尺寸、节点存储密钥量和Q值确定随机密钥预分配方案的弹性。指出传感器网络弹性、安全连通度和开销是相互矛盾的平衡关系。这些研究为特定应用场景传感器网络协议和算法的设计奠定了基础。更多还原

【Abstract】 Resilience against node capture is one of the main indicators of the key pre-distribution security in sensor networks. On providing the attack model and the definition of resilience against node capture of sensor networks, the resilience of basic random key pre-distribution, Q-composite random key pre-distribution and their reinforced models are analyzed and compared in depth. Research findings show that the size of key pool, the numbers of keys stored in nodes and the value of Q determine the resilience of random key pre-distribution. The tradeoff between the resilience, security connectivity and costs in sensor networks is presented. These researches lay a foundation on the design of the protocol and the algorithm in the specific application environment sensor networks.更多还原
