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.
