摘要: 介绍目前流行的同构型无线传感器网络的基本密钥预分配方案、q-composite密钥预分配方案和异构型无线传感器网络的密钥预分配方案,分析这3种密钥预分配方案的安全性。根据敌手对无线传感器网络的攻击能力,建立精确的敌手攻击模型,在该模型下提出一种安全弹性定量分析方法。概率分析和模拟实验结果表明,该方法可用于定量比较密钥预分配方案的安全性。

Abstract: In the field of security research of Wireless Sensor Networks(WSN), there exists three main kinds of key predistribution schemes, which are the basic key predistribution, the q-composite key predistribution scheme, both for homogeneous sensor networks, and the key predistribution scheme for heterogeneous sensor networks. By analyzing the security of all these key predistribution schemes, a more accurate threat model is established, and a flexible method for security quantitative analysis is presented. Statistical analysis and simulation experiments show that the method can evaluate in quantity the security of different key predistribution schemes.
