Abstract
A system and method for retrieving certificate of trust information for a certificate validation process. Fetching servers periodically retrieve certificate revocation lists (CRLs) from servers maintained by various certificate issuers. The revoked certificate data included in the retrieved CRLs are stored in a central database. An authentication server receives a request from a client for access to a secure service and initiates a validation process. The authentication server retrieves revoked certificate data from the central database and compares the retrieved revoked certificate data to certificate of trust information received from the client along with the request. The authentication server denies access to the secure information if the certificate of trust information matches revoked certificate data from the central database, allows access if the certificate of trust information does not match revoked certificate data from the central database.
