Hierarchical Key Management in Wireless Sensor Networks
Qiaoliang Li · Microcomputer Information · 2010
With the widening scale of wireless sensor networks,hierarchical topology is becoming dominant.Therefor,this paper proposes a multi-key space q-composite key pre-distribution scheme for hierarchical wireless sensor networks.The performance analysis by secure connection between nodes and nodes resist captured probability show that this scheme can increase the threshold of captured nodes,which is better resilient against attack,and improve the security of network..
