Abstract
The automatic dependent surveillance—broadcast (ADS-B) system adopts an open communication mode, and the lack of designed-in security measures in the ADS-B system makes it vulnerable to various types of attacks (jamming, spoofing, etc.). In view of the low-bandwidth and less-data-bit features of the ADS-B, this paper studies the integrity and authenticity of information by signing messages and proposes an ADS-B message authentication method based on certificateless short signature. This method uses short signature and does not require certificate management and has efficient performance. Compared with the existing approach, the computation costs of the proposed method in the signature phase are reduced by 1/2, and the signature length is reduced by 3/4. Additionally, we used the extended NS2 simulation platform to simulate 1090ES data link in different scenarios of the network; the simulation results show that our solution is suitable for minimum operational performance standard of ADS-B.

This paper considers an external adversary to the ADS-B system, which is capable of launching active adversarial threats to authenticity and integrity, such as spoofing ghost aircraft or damaging traffic data
Summary
The aviation industry has rapidly advanced and the number of planes has been increasing dramatically. The International Air Transport Association foresees that the number of passengers and tonnes of cargo that aviation will fly is going to be about 16 billion and 400 million, respectively, in the year 2050 [3]. It can be predicted that the number of airplane will continue to increase in the future, and airspace will become more and more crowded, which will pose great challenges to the conventional air traffic control (ATC) system. Due to the low precision and low refresh rate (4–10 s) of the conventional ATC system, it cannot meet the growth requirements of air traffic. Under this background, automatic dependent surveillance—broadcast (ADS-B) emerged
