Key pre-distribution scheme based on cluster in WSNs
Cao Qi-ying · Jisuanji yingyong yanjiu · 2009
To solve the problem of basic security for clustering in WSNs,this paper proposed a new bivariate polynomial key pre-distribution scheme based on two-tier hierarchical network architecture in WSNs.The scheme established pairwise key between any two cluster heads and suitable for the limited battery power,memory storage,and data processing capacity condition.The scheme not only successfully improved the network resilience against node capture attacks,but also solved the K-security problem of polynomial-key pre-distribution schemes.
