WSN密钥预分配方案的安全弹性定量分析

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。

Flexible Security Quantitative Analysis of Key Predistribution Schemes in WSN

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.
