摘要:
A method of ensuring secure and cost effective communication of aeronautical data to and from an aircraft is provided. The method includes uplinking air-ground aircraft data communications via an aeronautical safety data link and downlinking air-ground aircraft data communications via a consumer data link separated from the aeronautical safety data link by a one-way firewall.

Provided are methods and systems for the automatic calculation and presentation of data on a display device alerting a pilot that a change in flight plan is desirable, possible and administratively compliant under air traffic control protocol. The methods and systems may automatically request the flight clearance over a data link or the pilot may override the data link.

A method and apparatus for encrypting a Mode-S extended squitter exploiting a provided key. The key includes a control key segment, an address key segment, a first message key segment, and a first parity/identity key segment. Adding modulo two the control segment to the control key segment produces an intermediate control segment. Adding modulo two the address segment to the address key segment produces an intermediate address segment. Adding modulo two the message segment to the first message key segment produces an intermediate message segment. Adding modulo two the parity/identity segment to the first parity/identity key segment produces an first intermediate parity/identity segment. Concatenating the intermediate control segment, the intermediate address segment, the intermediate message segment, and the intermediate parity/identity segment produces an intermediate extended squitter. Shifting the intermediate extended squitter according to a linear function shift register produces a shifted-intermediate parity/identity segment.

Systems and methods for integration of IP-based data link management in existing avionics architectures are provided. In one embodiment, a communications management unit comprises: a legacy router providing access to a first set of air-ground data links; an internet protocol router providing access to a second set of air-ground data links; an applications and routing policy that provides criteria for selecting of a data link from one of the first set of air-ground data links or the second set of air-ground data links; and a data link manager that selects the data link from either the first set of air-ground data links and second sets of air-ground data links based on information provided by the applications and routing policy and controls the legacy router and the internet protocol router to route communication messages via the selected data link.

One embodiment is directed to a method for managing cryptographic information. The method includes initiating cryptographic information loading application on a general purpose mobile device (GPMD) and establishing a connection between the GPMD and a server that includes cryptographic information. Authentication input is received from a user of the GPMD. Data identifying the GPMD and the authentication input is sent from the GPMD to the server for authentication of the GPMD and the user. The GPMD also sends data identifying an electronic device into which cryptographic information is to be loaded. In response, the GPMD receives cryptographic information for the electronic device at the GPMD from the server. The GPMD then sends the cryptographic information from the GPMD to the electronic device for loading therein.

A method to facilitate securing of air-to-ground communications for an aircraft is provided. The method includes receiving security management information at the aircraft via at least one broadband data link prior to takeoff of the aircraft. The security management information is received for ground entities that can be communicatively coupled with the aircraft traveling on a flight path. The method of securing avionics also includes validating the security management information for the ground entities, and storing the validated security management information for the ground entities in the aircraft. The validating and storing of security management information occur prior to takeoff of the aircraft.

Systems and methods for dynamic transport protocol layer management for avionics system are provided. In one embodiment, a method for providing dynamic transport protocol layer management for avionics applications comprises: selecting an air-ground communication IP datalink based at least in part on criteria defined by one or more profile and policy definitions; selecting a transport layer protocol based on the air-ground communication IP datalink selected and further based on criteria defined by the one or more profile and policy definitions; and instantiating a port entity to transport air-ground communications between a first on-board application and the air-ground communication IP datalink through a Socket API, based on the selected transport layer protocol.
