The method includes providing, by the first LRU, a communication to the second LRU to request a certificate signing request (“CSR”) based on a public-private key pair generated by the second LRU; obtaining the CSR from the first LRU; providing the CSR and a certificate revocation request for a replaced LRU to a certificate authority (“CA”); obtaining a composite airline modifiable information (“AMI”) comprising a public key certificate associated with a private key generated by the first LRU; and providing the composite AMI to the first LRU.
