Cluster-based Group Key Management Scheme for Sensor Networks
Yaping Lin · Jisuanji gongcheng · 2008
There are no trust nodes in sensor networks as that in traditional networks. Based on cluster structure of sensor networks and thresholdsecret sharing mechanism, a novel group key management scheme for sensor networks is proposed in this paper, in which only innocent nodes havean efficient group key share. When group is rekeying, multiple entities in a local neighborhood can jointly create a new group key to be distributedby cluster heads securely. Analysis and simulations show that the scheme has lower memory and communication overheads besides good securityperformance.
