NASA Tests Blockchain to Secure Flight Data From Hackers

Your next flight could be protected by the same technology that secures cryptocurrency, thanks to NASA scientists who just proved blockchain can shield aircraft from hackers.

Researchers at NASA's Ames Research Center in California tested a blockchain-based system that keeps flight data safe from tampering. Using a custom-built drone, they showed the technology can protect information flowing between aircraft and ground stations in real time.

The timing couldn't be better. As air traffic grows more complex with delivery drones, air taxis, and autonomous aircraft, the old security systems face new threats. Hackers who intercept or manipulate flight data could cause serious safety problems.

Blockchain solves this by spreading information across a vast network instead of storing it in one place. Every change gets recorded and verified, making the data nearly impossible to hack. If someone tries to alter flight plans or location data, the system catches it immediately.

During the August test flight, the team flew an Alta-X drone equipped with special computers, radios, and GPS systems. They created a simulated real-world environment with a ground control station and the full blockchain security setup. The system successfully protected critical information like aircraft registration, flight plans, and telemetry data.

Only trusted users could access the protected information. The open-source framework gave approved operators real-time access to what they needed while keeping everyone else locked out.

The researchers even ran cybersecurity attack simulations to stress-test the system. The blockchain held strong, proving it could handle threats in active airspace.

The Ripple Effect

This technology extends far beyond today's commercial flights. The same framework that protected the test drone can secure high-altitude aircraft flying at 60,000 feet and future urban air mobility operations like flying taxis over cities.

Aviation companies across America now have a new tool to improve safety as air travel evolves. The research benefits everyone from major airlines to startups developing autonomous delivery systems.

NASA plans to analyze the test data and apply lessons learned to future projects. The work falls under the agency's Airspace Operations and Safety Program, which focuses on handling the growing demand for new types of aircraft.

As our skies get busier with innovative aircraft, this blockchain breakthrough ensures they stay safe.
