Secure aircraft data transmission using multiple communication channels

摘要

Provided are methods and systems for terrestrial data transmission between aircraft and external networks, such as airline networks and/or airport networks. While an aircraft is landed, various data domains may need to be transmitted between the aircraft and such networks using two or more communication channels available to the aircraft. These channels may include wired and/or wireless channels, such as broadband over power line channels, Ethernet channels, Wi-Fi channels, and cellular channels. The available communication channels are allocated to transmit particular data domains based on the security levels of these channels. For example, aircraft control domains may be transmitted using a more secure communication channel than passenger information domains and/or entertainment systems domains. In some embodiments, multiple communication channels may be used to transmit the same domain parsed into multiple transmission packets. The packets are recombined back into the data domain after the transmission.

主权项

1. A method for terrestrial data transmission between an aircraft and an external network, the method comprising:
identifying two or more communication channels available for terrestrial data transmission between the aircraft and the external network; and allocating data domains to be transmitted between the aircraft and the external network to each of the two or more communication channels based on a channel security level of each of the two or more communication channels,
wherein at least two of the two or more communication channels are allocated to transmit the same data domain of the data domains; and generating instructions for reconstructing the same data domain after the same data domain is transmitted using the at least two of the two or more communication channels.
