  • Patent number: 10951418
    Abstract: Systems and methods of managing enrollment of digital identities (e.g., for aeronautical communication) can involve a line-replaceable unit (LRU) in an aircraft establishing a digital identity with a ground-based server by requesting a public certificate from the ground-based server. The LRU may receive a public certificate from the ground-based server. The LRU may validate the public certificate. The LRU may generate, based on validating the public certificate, an enrollment status message indicative of at least one status code from a plurality of predefined status codes associated with a plurality of corresponding actions for the ground-based server. The LRU may transmit the enrollment status message including the at least one status code to the ground-based server, to cause the ground-based server to perform a corresponding action based on the at least one status code.
