  4. Abstract:
  5. Using the public network for distributed computations compromises the immunity of control loops to cyberattacks such as data manipulation and eavesdropping. These risks have forced control system engineers to find solutions to protect control systems against these dangers. Encrypted control studies these dangers and tries to propose new modified control systems to increase the immunity of the control systems. Secret sharing is one of the tools used in the encrypted control field. In this paper, we modify this tool to propose an algorithm to design a secure control system. This scheme while guarantees the security of the control systems, can attenuate the measurement noise as well. To achieve resilience against measurement noise, we can iteratively use secret sharing while adding white noise with suitable variance to the shares of our data. Increased security, secure distributed computation, and measurement noise attenuation are some of the results of using this control system scheme compared to the conventional control systems. © 2023 IEEE
