Secure data exchange in the control system of unmanned aerial vehicles (UAVs) is an important aspect for preventing unauthorized access and safety of aerial vehicles. Given the problems of automatic dependent surveillance-broadcast (ADS-B) data protection, the safety level of UAV flight tasks and air traffic in general is significantly reduced. Therefore, the protection of ADS-B data is an urgent task. The object of the study is the process of steganographic protection of ADS-B format data. A relevant problem of estimating the probabilistic time characteristics of the steganographic protection process is solved, taking into account the features of data embedding in the ADS-B format container. To solve it, a mathematical formalization of the methods of finding probabilistic-temporal characteristics of steganographic systems was carried out. A model of steganographic data transformation operations based on the Chinese remainder theorem has been built. The main difference of the model is taking into account the features of the ADS-B format data. This made it possible to formalize and evaluate the time functions of steganographic encoding and decoding of UAV identifiers with an integrated ADS-B system. A model of steganographic data transformation operations based on the finite integral ring theorem has been constructed. A list of operations performed in the developed algorithm has been compiled. This made it possible to carry out mathematical formalization of operations for complex use in the model of steganographic protection of UAV identifiers with a built-in ADS-B system. The mathematical model was studied and the estimation of the random value of the time of steganographic transformation of data, as well as the confidence interval, was performed. With the help of the reported set of models, it is possible to estimate the probability of the algorithm’s execution time falling within the given interval. The results of the calculation of probabilistic-time characteristics could be used in models of a higher level of the hierarchy

“…To detect spoofing, i.e. for the protection of wireless ADS-B communication, various security methods have been proposed, based on the existing cryptographic techniques (Finke et al, 2013), (Alghamdi et al, 2018). An alternative to this are necryptographic approaches which are based on signal separation (PHY-layer signal separation) (Leonardi et al, 2017), time and position verification (Schäfer et al, 2015), Doppler shift (Schäfer et al, 2016), etc.…”

Introduction/purpose: The paper provides a review of recent research in the field of GPS and ADS-B spoofing. Systems that rely on satellite positioning technology can be targeted by spoofing in order to generate incorrect positioning/timing, which is accomplished by inserting false signals into the "victim's" receiver. Attackers try to insert false positioning information into systems that, for example, provide navigation of airplanes or drones for the purpose of hijacking or distracting security/safety in airspace surveillance. New concepts of navigation and ATC will thus be necessary. Methods: Using a scientific approach, the paper gives an evaluation of GPS and ADS-B spoofing/antispoofing and how spoofing affects the cyber security of aviation systems. Results: Based on the methodological analysis used, the importance of studying spoofing/anti-spoofing in aviation is shown. Conclusion: Although spoofing in aviation is only a potential threat, its technical feasibility is realistic and its potential is considerable; it becomes more flexible and cheaper due to very rapid advancement of SDR technologies. The real risk, in the time to come, are potential spoofing attacks that could occur from the air, using drones. However, aircraft systems are not exposed to spoofing without any defense; receivers can detect it by applying various anti-spufing techniques. Also, pilots are able to detect and solve problems at every stage of the flight. However, due to a possibility of more sophisticated spoofing attacks, international organizations such as ICAO are proactively working to increase GPS and ADS-B systems robustness on spoofing.

“…It can be seen from the above that the Kalman filter algorithm can no longer store the previous information. Referring to the linear progressive method, the estimated value of the initial state and the Based on its covariance matrix, it is possible to obtain an estimate of the situation at the next time, revising the size of the estimate and reducing the computational and storage capacity [18]. Because of this, the Kalman filter has an estimate-revision composition, implemented as a linearly progressive algorithm for an optimal estimate.…”

Automatic Dependent Surveillance-Broadcast (ADS-B) technology is a kind of aircraft operation surveillance technology that has emerged in recent years. It has been widely regarded as the core technology of next-generation aviation surveillance in the international community. Many countries have already adopted ADS-B technology. For a relatively mature system, my country is also actively promoting the application of ADS-B technology. The research purpose of this paper is the ADS-B distributed processing system based on parallel computing on the general platform. In the experiment, the processing flow of the system is analyzed and the basic mathematical functions are used. Experiments and analysis are carried out on the carrier frequency test and carrier power test of the ADS-B system, as well as the ADS-B track filtering and processing system based on the parallel algorithm.
