一种高连通率的传感器网络密钥预分配方法
A high connectivity rate key pre-distribution scheme in sensor network
摘要
Abstract
Key management is the base of wireless sensor network security, key pre-distribution ( KPS) is a high feasibility method in key management, the probability of sharing key between the nodes is always the important property in KPS, however, most of the existing wireless sensor network key distribution schemes have the problem of low probability of sharing keys between nodes , or the probability of sharing keys between nodes is not stable. With blom symmetric polynomials, by improving TD scheme, proposed a improved key pre-distribution scheme, this method could achieve a stable high-key sharing probability between nodes. Thus ensuring the security of wireless sensor network connectivity, in addition, the method also had the characteristics of a flexible variable, it could change the number of sensors and sensor storage group key number to meet the actual demand.关键词
