Abstract:
A method or network that addresses cybersecurity vulnerabilities in an ADS-B network by validating and authenticating ADS-B messages. Nodes of the network maintain a validated ledger of ADS-B transactions and use validated information from this ledger to improve security against common cybersecurity attacks including, but not limited to, denial of service attacks, jamming attacks, spoofing attacks, flooding attacks and eavesdropping.

Claim (Index 1):
A method to ensure ADS-B message security by implementing a distributed ledger for protecting validity and authenticity of ADS-B transactions within a network having a plurality of nodes, one or more of the of the nodes performing the method comprising:\n receiving a whole or part of the distributed ledger containing one or more blocks of the ADS-B transactions by a validation module, each block comprising a set of states and other information pertaining to one of the other nodes in the network; appending the whole or part of the distributed ledger to an existing local copy of the distributed ledger to create an unvalidated updated local copy of the distributed ledger; broadcasting the updated local copy of the distributed ledger to the other nodes; implementing a consensus algorithm to validate and authenticate the updated local copy of the distributed ledger; broadcasting whole or part of the validated and authenticated updated local copy to other ones of the nodes in ADS-B range, and receiving from the other ones of the nodes their whole or part of the validated and authenticated updated local copy; and replacing whole or part of the existing local copy of the distributed ledger with at least a part of the received whole or part of the validated and authenticated local copy of the distributed ledger.
