Abstract

The present invention generally relates to one or more line replacement units ('LRUs') for an airplane. The LRUs can include airline modifiable information ('AMI') that includes more than one public key certificates, wherein each of the more than one public key certificates uniquely identifies the airplane for ground communication based, at least in part, on a public key or a private key associated with the one or more public / private key pairs generated by a cryptographic key generator.

Description

technical field [0001] The present invention generally relates to transferring data to, from or within an aircraft in a secure manner. Background technique [0002] The latest generation of aircraft, such as the Boeing 787 and Airbus A350, include aircraft data networks that introduce potential cybersecurity weaknesses. Cybersecurity vulnerabilities are not a new concept, however they are new with respect to airworthiness. This network provides connections between the aircraft and ground systems for transferring data to and from the aircraft, as well as connections to maintenance ground support equipment. Aircraft cybersecurity procedures are required to protect this data link. [0003] Traditional aircraft design involves the use of data buses such as ARINC 429 / 629 or MIL-STD-1553. The latest aircraft designs may use, among other things, the non-aviation standard TCP / IP to convey a variety of digital information including, but not limited to, passenger information and en...
