提出一种引入等级服务权重的Ad Hoc网络证书撤销算法,是一种分布式算法。该算法利用撤销关系记录矩阵R(T)、节点证书特征值记录矩阵V(T)描述节点间的撤销关系和节点的可信度,利用等级服务评价函数W(T)依据服务等级引入权重因子影响节点的可信度;通过矩阵运算逐步实现网络运行过程中节点证书特征值的更新,从而实现Ad Hoc网络运行过程中节点证书的有效管理。 An Ad Hoc network certificate revocation algorithm which introduces the weight of service level is proposed. It is a distributed algorithm. This algorithm describes the revocation relations and the credibility of the nodes by using the revocation relations record matrix R (T) and the node certificate eigenvalue record matrix V (T), and uses the rating service evaluation function W (T) to introduce the weight factor Affect the credibility of the node; and gradually update the eigenvalue of the node certificate in the network operation process through the matrix operation so as to effectively manage the node certificate during the operation of the Ad Hoc network.
