ABSTRACT:
A method of updating a locally cached revocation list of digital certificates in a client computer with a current data base of revoked certificates stored in a host computer. Upon receipt of a digital certificate submitted to the client computer for verification, the client computer checks the submitted digital certificate against the locally cached revocation list. If the submitted digital certificate is not on the locally cached revocation list, the client computer confirms the validity of the submitted digital certificate and the transaction is consummated. If however, the submitted digital certificate is on the revocation list, the client computer establishes a communication link with the host computer and determines if the submitted digital certificate is in the data base of revoked certificates on the host computer. Without breaking the communication link, the client may request that an updated revocation list to be downloaded.
