Algorithm for Verifying the Authenticity of Actuators in Automated Process Control Systems

The paper proposes an algorithm for verifying the authenticity of automated process control system actuators based on the HART standard, which can act as the main or additional measure of protection against threats to the integrity of the system. The principle of operation of the HART standard is considered, a theoretical algorithm is given, additional technical solutions that increase its reliability are considered, as well as scenarios of possible attacks.
