Abstract
A control system for a technical installation, in particular a process or manufacturing installation, includes at least one component upon which a certificate service is computer implemented, wherein the certificate service is configured to check a certificate store that is assigned to the component or a further component to determine whether two or more certificates, which only differ from one another in terms of their validity period, are stored in the certificate store, and in the event of the check identifying two or more certificates of this type, to initiate revocation and removal from the certificate store of the certificate or certificates with the validity period that ends the earliest, such that only the certificate with the validity period that ends the latest remains stored in the certificate store.
