NASA tests blockchain system to secure flight data against cyber threats
NASA has flight-tested a blockchain-based system designed to protect aviation data from interception, manipulation and disruption.
The test took place at NASA's Ames Research Center in California's Silicon Valley, where researchers used a drone to examine whether blockchain could strengthen trust in data shared across airspace systems. The goal was to secure information moving between aircraft and ground stations as aviation networks become more connected and cyber threats grow more sophisticated. NASA said the test showed the system could transmit and store flight information securely in real time, a key requirement for safe air traffic operations.
Instead of relying on a single central database, the system uses blockchain to distribute records across a network where changes are logged and verified collectively. NASA used an open-source blockchain framework to allow trusted users to share and store critical operational data, including aircraft operator registration details, flight plans and telemetry. Access was limited to approved participants. Researchers also ran cybersecurity exercises during the trial to measure how the system performed under stress and to identify ways to strengthen protection during live airspace operations.
The August demonstration used an Alta-X drone equipped with a custom package that included a computer, radio, GPS and battery systems. The test environment paired the aircraft with a separate ground control station and supporting blockchain and security infrastructure to simulate real-world conditions. NASA said the framework could support several emerging aviation sectors, including autonomous air traffic management, urban air mobility and high-altitude operations above 60,000 feet. That matters because each of those areas depends on fast, trusted exchanges of data among multiple operators and automated systems.
NASA said it will continue analyzing the test results and apply the findings to future work under its air traffic management and safety research efforts. If the approach matures, it could give U.S. aviation stakeholders a new tool to secure digital operations as the airspace absorbs more drones, advanced aircraft and automated services.
