NASA experiments with blockchain to protect drone flight data

NASA has successfully tested a blockchain-based cybersecurity system aimed at safeguarding drone flight data from hacking and unauthorized changes. The trials were carried out at the agency’s Ames Research Center in California, where researchers demonstrated how blockchain technology can secure real-time communication between drones and ground control systems.

As digital threats to aviation continue to grow, NASA is looking beyond traditional layered security models. The blockchain solution creates an immutable digital ledger, making it extremely difficult for data to be altered once recorded. This approach helps ensure the integrity of critical flight information, including telemetry data, flight paths and operator identification details.

During a flight test conducted in August, researchers used an Alta-X drone operating under conditions that closely resembled real-world airspace environments. The drone was equipped with a customized hardware and software setup that relied on an open-source blockchain framework. The system successfully processed secure digital transactions at speeds suitable for live air traffic operations, proving that blockchain can meet both performance and safety requirements.

NASA believes this technology could play an important role in the future of aviation. It is especially relevant for emerging sectors such as Urban Air Mobility, where air taxis and delivery drones will require secure, automated coordination. The system may also benefit high-altitude autonomous aircraft operating above 60,000 feet, where secure data exchange is critical.

By confirming that blockchain can reliably store and transmit aviation data in real time, NASA aims to develop a scalable and trusted digital ecosystem. This effort supports the broader goal of enabling safer, more secure next-generation air travel systems.
