中文摘要：

通过分析Ad Hoc网络中证书撤销机制存在的问题,提出了一个适用于该网络的分布式证书撤销机制.该机制包含证书撤销算法和证书撤销实现过程.引入四个因素进一步完善了证书撤销算法,提高了节点自觉监控网络的能力和积极性;并通过要求网络中所有节点各自维护两张表,有效地降低节点证书撤销过程中的通信.

英文摘要：

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.
