Abstract
The validity status of a digital certificate is accessible even after a certificate has expired. Certificate validity status is stored and retained in a certificate status history database that allows for ease of certificate status retrieval. The validity status of a certificate can be determined for a specified point in time. It is no longer necessary to review multiple certificate revocation lists to determine the validity status of a digital certificate. Status historical information regarding multiple certificate renewals, suspensions and reinstatements can also be obtained from the database.
