Solution Overview
Problem
Civilian unmanned aerial vehicles (UAVs) are under-regulated and susceptible to cyber-attacks due to lack of secure management and tracking systems, posing risks as they become more prevalent.
Innovation Solution
Implementing a blockchain-based distributed ledger system for securely managing and tracking UAV flight paths, using cryptographic keys to authenticate and verify the progress of UAVs, ensuring immutability and integrity of data, and enabling real-time monitoring and correction of flight plans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blockchain-based distributed ledger system is implemented for tracking UAVs, then security and data integrity are improved, but device complexity increases
Solution Approach 1:
A blockchain-based distributed ledger system acts as an intermediary between UAVs and ground control stations, providing secure and transparent tracking. The blockchain network mediates data exchange, ensuring immutability and integrity of flight path records while distributing trust across multiple nodes rather than relying on a single centralized authority.
2Reliability
If cryptographic keys are used to authenticate UAVs and verify flight progress, then reliability and security are improved, but ease of operation deteriorates
Solution Approach 1:
Cryptographic key pairs are generated and distributed to UAVs before flight operations begin. The authentication mechanism is pre-configured, allowing UAVs to automatically sign flight path data and receive verification from the blockchain network without requiring manual cryptographic operations during flight, thus maintaining ease of operation while ensuring security.
3Reliability
If real-time monitoring and correction of flight plans is enabled, then reliability and safety are improved, but loss of time in processing and communication increases
Solution Approach 1:
The blockchain-based system provides continuous feedback on UAV flight progress by recording and verifying flight path data in real-time. Ground control stations can monitor flight status and request corrections through the blockchain network, enabling timely interventions while maintaining a streamlined process through automated verification and reduced communication overhead.

AI summary
Techniques are described herein for securely managing and tracking UAV flight paths. The techniques include receiving a flight plan from an unmanned aerial vehicle (UAV). The UAV comprises a memory unit for storing a key associated with the UAV. The key enables the UAV to add one or more blocks on a blockchain distributed ledger, wherein the flight plan comprises one or more legs of a flight path. The techniques further include receiving, from the UAV, a block indicating that the UAV completed at least one leg of the flight path. The block can include a hash associated with the at least one leg of the flight path. The block is validated based at least on the hash associated with the at least one leg of the flight path and if the block is validated, a success notification is transmitted to the UAV to continue executing the flight plan.
