A Hybrid Key Management Scheme Based on Clustered Wireless Sensor Networks
Pengcheng Zhao, Yong Chun Xu, Nan Min · Wireless Sensor Network · 2012
According to the weakness of session key construction based on node’s own location, we propose a hybrid key management scheme which based on clustered wireless sensor networks. The use of hierarchical thinking, reducing the amount of key storage and computing, while supporting network topology, dynamic key management for which aims to prevent leakage. Through analyzing, it shows that the scheme have certain advantages in key connectivity, security, communication and energy consumption.
