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.
Claims20
A hardware line replacement unit (“LRU”) for an airplane, comprising:
- an airline modifiable information (“AMI”) comprising more than one public key certificates, wherein each of the more than one public key certificates provide a unique and separate identity for each airplane among a fleet of airplanes for ground communication, wherein a first public key certificate of the more than one public key certificates for the airplane is based, at least in part, on a public key associated with one or more public/private key pairs generated by a cryptographic key generator, wherein the public key is stored on the LRU and a second public key certificate of the more than one public key certificates is for another airplane among the fleet of airplanes,
- the cryptographic key generator operable to generate the one or more public/private key pairs;
- and
- a memory operable to store the one or more public/private key pairs.
1 more element
An airplane comprising:
- a first line replacement unit (“LRU”);
- a second LRU,
- wherein the first LRU and the second LRU each comprise:
- an airline modifiable information (“AMI”) comprising:
- a first public key certificate, wherein the first public key certificate provides a first unique identity for the airplane among a fleet of airplanes for ground communication based, at least in part, on a first public key associated with a first public/private key pair generated by a first cryptographic key generator, wherein the first public key is stored on the first LRU;
- and
- a second public key certificate, wherein the second public key certificate provides a second unique identity for another airplane among the fleet of airplanes for ground communication based, at least in part, on a second public key associated with a second public/private key pair generated by a second cryptographic key generator, wherein the second public key is stored on the second LRU.
