An Improvement of Hypercube-Based Key Pre-Distribution Scheme for Wireless Sensor Network
Cheng Chao · Journal of Beijing Jiaotong University · 2009
Security becomes the most important and basic aspect of WSN research because of WSN's own characteristics,especially the key management mechanism.The paper proposed an improvement of the Hypercube-based scheme based on dual-variate polynomials by deep analysis.The new scheme reserves the merit of less memory than other schemes and overcomes the drawback of lacking key update ability.The new Hypercube-based scheme can update key and improve the system security with little memory increase.It is more suitable for WSN's practical application.
