USE OF DATA LINKS FOR AERONAUTICAL PURPOSES WITHOUT COMPROMISING SAFETY AND SECURITY

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.

主权项

1. A method of ensuring secure communication of aeronautical data to and from an aircraft, the method comprising:
uplinking air-ground aircraft data communications via an aeronautical safety data link, wherein the aeronautical safety data link is at least one of: a communications link licensed to exchange safety/security data between the aircraft and at least one of a mobile system and a fixed system; or a communications link regulated to exchange the safety/security data between the aircraft and at least one of the mobile system and the fixed system; and determining which of at least two data links to use for downlinks of the safety/security data based on at least one of:
a type of message to be downlinked; anda size of message to be downlinked, the at least two data links including the aeronautical safety data link and at least one consumer data link, wherein the at least one consumer data link is separated from the aeronautical safety data link by a one-way firewall.
