Software Part Validation Using Hash Values

摘要

A system and method for validating software parts on an aircraft. A first hash value is calculated for a software part on the aircraft. A determination is made on the aircraft as to whether the first hash value matches a second hash value from a software integrity data structure stored on the aircraft. The software integrity data structure comprises the hash values that are not determined on the aircraft for the software parts used by the aircraft. A validation status is provided based on whether the first hash value matches the second hash value. An operation is performed on the software part on the aircraft only if the first hash value matches the second hash value.
