Key management scheme for wireless sensor network based on multiple key spaces
Haipeng Qu · Journal of Computer Applications · 2009
This paper proposed a key management scheme based on the pairwise key predistribution scheme for Wireless Sensor Network(WSN).This scheme combined the q-composite random key predistribution scheme and introduced the location information to enhance secure connection probability between nodes.The analysis results show that this scheme doesn't need additional memory space and increases the probability that neighbor nodes have the same key space.Compared with the pairwise key predistribution scheme,this scheme can increase the threshold of captured nodes and improve the security of WSN,and fits the network environment and meets the security requirements of WSN.
