Abstract: Embodiments described herein provide for a system for verifying integrity of files uplinked to a remote vehicle. The system is configured to receive a first message authentication code (MAC) for the uplinked file, a first acknowledgement MAC for the MAC, and a first cyclic redundancy check (CRC) for the first MAC and the acknowledgement MAC. The system is also configured to compute a second MAC from the uplinked file, a second acknowledgement MAC from the second MAC and a second CRC from the second MAC and second acknowledgement MAC. Integrity of the uplinked file is verified by comparing the first CRC with the second CRC. If integrity of the uplinked file is confirmed, the uplinked file is accepted. If integrity of the uplinked file is not confirmed, the uplinked file is rejected.
