Application: Control system for technical plants having certificate management (Patent ID: US20230275767A1)
Siemens AG has filed a patent for a control system designed for technical plants, such as manufacturing or processing plants. The control system includes a computer-implemented revocation service that automates the process of initiating the revocation of certificates for components of the plant as part of certificate management. The revocation service is event-controlled, meaning it is triggered by specific events, such as changes in communication links between components, without the need for component replacement or removal.
The control system is configured to initiate both the issuance and revocation of certificates for the components of the technical plant. The revocation service sends a revocation request to a certification authority and monitors the processing of the request. After the revocation of certificates, the control system makes the revocation known within the system, potentially using a blocklist format.
In summary, the patent describes a control system that automates the process of issuing and revoking certificates for components of a technical plant. The revocation service is event-controlled and can be triggered by changes in communication links between components. The system also includes monitoring capabilities for the revocation request processing and provides a mechanism for making the revocation known within the control system.
