SUMMARY:

In this work, a study is presented regarding the vulnerabilities of ADS-B communication (Automatic Dependent Surveillance – Broadcast), considering above all the risks to operational security. This technology was developed to transmit surveillance information, that is, data related to position, altimetry and speed, from the avionics of the aircraft itself, being an evolution to radars. An encryption solution is developed for this communication using format-preserving encryption, also assessing the use of symmetric block ciphers used in a lightweight environment, such as the Internet of Things, in order to obtain better computational performance. in solutions with embedded systems. It is observed that such ciphers, when used as a pseudorandom function, maintain a high entropy value with low computational cost, meeting the desired security levels. This study is related to similar research with the objective of confronting the different approaches and complementing the studies. Finally, the computational performance obtained with the proposed solution is analyzed by processing real data from aircraft in the landing and takeoff phase at the International Airport of Recife/Guararapes - Gilberto Freyre, based in Recife/PE.
