Abstract
A certificate management apparatus retains an important certificate, while deleting the oldest referenced certificate. An update determination information output unit outputs update determination information being information for determining whether or not to update a certificate. A certificate cache stores the certificate on a volatile memory. An operation unit stores the update determination information output by the update determination information output unit in the certificate cache by relating to the certificate, and based on the update determination information stored in the certificate cache, updates the certificate related to the update determination information.
