| 摘 要： | 提出了一种针对节点沦陷情况下的随机密钥预分配模型的细粒度分析方法．为3种具有代表性的密钥预分配模型：基础密钥预分配模型、q—composite随机密钥预分配模型和非平衡密钥预分配模型，在节点沦陷的情况下，提出了一种更适宜的威胁模型和安全弹性定义．本文的分析工作比以往关于密钥预分配模型的分析更为精确．

| Abstract: | A fine grained formal analysis on resilience against node compromise in probabilistic key predistribution scheme for sensor networks is presented. Targeting at three representative key pre-distribution schemes, basic key pre-distribution scheme, q -composite key pre-distribution scheme and an unbalanced key pre-distribution scheme, we propose a more suitable threat model and definition of resiliency against node compromise for probabilistic key pre-distribution schemes. This is proved much more precise than the ones in the refermes which proposed these schemes. |
