NETWORK SECURITY FRAMEWORK FOR WIRELESS AIRCRAFT COMMUNICATION
First Claim
Patent Images
1. A method for implementing a network security framework for wireless aircraft communication, comprising:
- receiving a key index sequence over a first communication link;
transmitting a subset of the key index to one or more nodes;
generating a random encryption key based at least in part on the subset of the key index sequence;
encrypting data using the random encryption key; and
transmitting the encrypted data over a second communication link.

8. A system for implementing a network security framework for wireless aircraft communication, comprising:
-
a first node; one or more second nodes, wherein the first node is connected to the one or more second nodes over a first communication link, wherein the first node transmits a key index sequence to the one or more second nodes; and one or more third nodes, wherein the one or more second nodes are connected to the one or more third node over a second communication link, wherein the one or more second nodes transmits a subset of the key index sequence to the one or more third nodes to generate random encryption keys based at least in part on the subset of the key index sequence. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A device for implementing a network security framework for wireless aircraft communication, comprising:
-
a first interface configured to receive a first message from the aircraft interface device over a first communication link, wherein the first message includes a key index; a second interface configured to transmit a second message to one or more sensors, wherein the second message includes a subset of the key index; an encryption key generator module configured to generate an encryption key based on the second message and encrypt a message using the encryption key; and transmitting encrypted messages over a second communication link. - View Dependent Claims (19, 20)
