Grid-based Predistribution Secret Key Mechanism for Wireless Sensor Network
Fuyou Miao · Jisuanji gongcheng · 2011
In order to overcome the shortcomings of connectivity and resilience,which are poor in most other secret key predistribution mechanism for Wireless Sensor Network(WSN),this paper proposes a mechanism based on grid.This mechanism can not only guarantee the establishment of secret key pair directly between two adjacent nodes,but also can ensure that the disclose of some secret key space in the area attacked by the enemy cannot affect the security of sensors in other safe area.Besides,the compromised sensors can be removed easily as a whole,facilitating the update of the network.Experimental results show that the mechanism has good connectivity and resilience.
