An Improvement of Hypercube-Based Key Pre-Distribution Scheme for Wireless Sensor Network

WU Hao,CHENG Chao(State Key Laboratory of Rail Traffic Control and Safety,Beijing Jiaotong University,Beijing 100044,China)  
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.
