An Improved Overlap-Key-Sharing Key Management Scheme for Wireless Sensor Networks

چکیده
Key management is the base of wireless sensor network security, key pre-distribution way is a high feasibility method in key management. The network connectivity rate, resilience against node capture and the storage consumption are important performance indicators in key pre-distribution way. However, most of the existing key pre-distribution schemes of wireless sensor network have the problems of low connectivity rate , large storage consumption or poor resilience against node capture .On the basis of Overlap-Key-Sharing (OKS) management scheme and the group-based model of Wenliang Du and Donggang Liu et, an improved Overlap-Key-Sharing key management scheme is proposed. The management scheme has little storage consumption and good resilience against node capture. In this paper, we mainly do some analyses and evaluations on a basic random key pre-distribution scheme (E-G scheme) which is proposed by Eschenauer and Gligor et and the improved Overlap-Key-Sharing key management scheme. Result analyses show that under the same network connectivity rate, compared to E-G management scheme, the improved scheme has better resilience against node capture and the smaller storage consumption.
