Abstract: A device implementing a digital credential revocation system includes at least one processor configured to maintain a valid digital credential list, a revocation list, and a synchronization counter value. The at least one processor is configured to transmit a request to synchronize the valid digital credential list with an electronic device, the request including the valid digital credential list and the revocation list. The at least one processor is further configured to, in response to receipt of an updated valid digital credential list from the electronic device: clear the revocation list, replace the valid digital credential list with the updated valid digital credential list, and increment the synchronization counter value, and fulfill a received credential maintenance request when the received credential maintenance request comprises an other synchronization counter value that is greater than or equal to the incremented synchronization counter value, otherwise deny the received credential maintenance request.
