PROBLEM TO BE SOLVED: To provide a managing method for information regarding revocation of a certificate that can suppress the risk that an illegal connection is made within the time up to update of a certificate revocation list CRL wherein the information on the revocation of the certificate is speedily reflected on the certificate revocation list CRL of other existent nodes in a network which comprises a plurality of nodes and on which the respective nodes authenticate one another and can communicate directly with one another, and an information processor as a node constituting the network. SOLUTION: When a certificate is revoked, for example, when a node leaves the network, the leaving node transmits notice of its leaving to all other existent nodes to which the node can be directly connected to prompt update of connection tables and revocation lists that they hold.
