Security Assist Mechanisms for Industrial Control Systems with Authentication

Due to a lack of identification and authentication in the communication protocol used for industrial control systems. It is easy for an intruder to forge false information or impersonate a device to send inappropriate commands to other devices, causing them to malfunction or be damaged. This study designs three kinds of identity security mechanisms used in industrial control communication protocols: central control, device to device (D2D), and a hybrid mechanism combining the above two. Using the proposed mechanism can prevent intruders from disguising as legitimate devices to join the industrial network, resulting in information tampering or equipment impersonation.
