Abstract: A computer implemented method, apparatus, and computer program product for transferring information with an aircraft. A connection is established between an onboard electronic distribution system executing in an aircraft data processing system in the aircraft and an on ground component. Responsive to a request for a command from the on ground component, the command for execution is identified. The identified command is sent to the onboard electronic distribution system from an on ground component. A transaction identifier is assigned to the command. A transaction associated with the command is maintained on the onboard electronic distribution system and the on ground component using the transaction identifier. An uplink is initiated by the on ground component. An aircraft software part is sent to the onboard electronic distribution system from the on ground component to perform the uplink. A status of a transfer of the aircraft software part on ground component is stored.

Abstract: A system and method are disclosed for establishing hierarchal subcomponent sensor communication for a vehicle. A database includes information associated with a plurality of subcomponents having a sensor. A software modeling tool implements a safety model and a fault detection and isolation (FDI) model. The safety model determines a probability of a constraint being violated given a probability of failure of each subcomponent. The FDI model determines a probability associated with a risk exposure for known and unknown faults for each subcomponent. A processor identifies those subcomponent sensors that reduce risk-exposure based on probabilities generated using the safety model and FDI model and generates an output of a set of vehicle subcomponent sensors for connection to an vehicle communication system for communication at a higher level of hierarchy, such that the vehicle communication system can receive information indicative of a subcomponent fault and generate an alert about the fault.

Abstract: Systems and methods for trusted mobile communications are described. A network system provisions a mobile client system with a collection of security parameters on a per application basis and a per device basis. The airplane system provides access to the mobile client system based on the established chain of trust without previously having information about the mobile client system even when the mobile client system and the airplane system are offline with respect to the network system.

Abstract: A computing device, computer system and associated method are provided to mediate a conversation in a manner that facilitates the inclusion of semantic tags within the conversation. In the context of a method, user input may be received relating to maintenance of a system. The method also determines, with processing circuitry, a candidate tag based upon semantic context of the user input. Additionally, the method provides an indication of the candidate tag to the user and receives a response from the user regarding validity of the candidate tag with respect to the semantic context of the user input. The method may also store the maintenance report including the user input and an associated tag. A corresponding mediation computing device and an associated computer system are also provided.

Abstract: Methods, apparatus and computer program products are provided to authenticate and determine the integrity a software part. In this regard, a software part is authenticated and its integrity is determined by determining a first hash of the digital data that comprises the software part. If the air vehicle lacks data communications connectivity with an off-board security system, the method determines the authenticity and integrity of the software part by decrypting an encrypted hash of a software part in accordance with a public-private key pair to create a decrypted hash, comparing the first hash with the decrypted hash and transmitting the first hash to the off-board security system once data communications connectivity is established. Conversely, if the air vehicle has data communications connectivity with the off-board security system, the method determines the integrity of the software part by transmitting the first hash to the off-board security system for comparison with a whitelist.
