Providing certificate service scheme in cluser-based mobile Ad hoc network
YU Mei-sheng · Computer Engineering and Applications Journal · 2008
In MANET,there exist lots of limitations in the aspect of security due to its properties,so higher demands about authentication have been presented.In this paper a certification service scheme in the cluster-based architecture is proposed according to authentication technique of threshold mechanism,and the problem that the number of one-hop neighbor nodes is less than threshold value is resolved.At the same time,the authors adopt Feldman’s VSS strategy to prevent malicious nodes from providing false partial certificates,and then to decrease unreliable wireless channel’s influence on CA.Meanwhile,the synthesis efficiency of certificates is increased,and hostile counterfeit attacking can be prevented effectively.
