A Blockchain Method to IoT Sensors for Data Security in Aviation Surveillance

Open source IoT sensors, where distributed, could submit aviation surveillance data from around the world to third-party platforms in a centralized manner. This has become the mainstream method for aviation data fusion and collaborative prediction. However, there are many network security problems in the current aviation surveillance system, particularly the issue of fake data submitted by “unreliable” IoT sensors. This paper proposes a consensus mechanism based on the consortium chain in which ICAO member states can join to share aviation surveillance data. Additionally, using a blockchain smart contract-based solution can solve the network security problem of air surveillance IoT volunteer sensors around the world. Through the analysis and testing of nearly 100,000 pieces of aviation surveillance data, the results demonstrate that the proposed scheme has the characteristics of easy error correction for noise, updateable strategy, and high storage efficiency, and has practicality in the field of air traffic control.
