Abstract

This study aims at proposing a novel concept of a secured controller to achieve enhancement of cyber-security in networked control systems using RSA public-key encryption. With homomorphism of the RSA encryption, the proposed method enables to conceal not only signals over communication links in the control systems, but also parameters of controllers used in determining a control input. A numerical example is employed to confirm that the proposed method correctly functions for the cyber-security enhancement.
