A Distributed Certificate Revocation Scheme for Ad Hoc Networks

By analyzing the problem of certificate revocation scheme existing in Ad Hoc network, this paper presents a new distributed certificate revocation scheme. The algorithm and the whole process of revocation are included in this scheme. By introducing four factors, the algorithm of certificate revocation becomes more perfect. The monitoring ability and enthusiasm of each node are enhanced as well. Besides, the traffic load in the process of certificate revocation is effectively reduced after requiring that each node maintain and refresh its two tables.
