Abstract
A secure onboard maintenance circuit (OMC) includes a primary OMC node with a controller, a secure storage, a trusted CDS interface, and a configurable I/O interface for connecting to at least one system component. The controller is configured to receive maintenance information via the configurable I/O interface and the trusted CDS interface and is further configured to store data associated with the maintenance information in the secure storage. The OMC further includes at least one secondary OMC node with a second controller, a second trusted CDS interface, and a second configurable I/O interface for connecting to at least one other system component. The second controller is configured to receive maintenance information via the second configurable I/O interface and is further configured to transmit the maintenance information to the primary OMC node via the second trusted CDS interface.
