説明

<p>Control systems such as factory production systems and mobility systems require countermeasures to prevent serious physical damage from cyber-attacks. Although there have been reported cases of attacks such as installation of unauthorized devices in internal networks and physical tampering with vehicle networks, sufficient countermeasures have not yet been taken in the control systems currently in operation. In this paper, we propose a method to detect network route tampering by adding calculation and communication functions for network tampering detection to devices and components that make up bus-type networks commonly used in field networks. The proposed method makes it possible to detect anomalies caused by network route tampering without changing the specifications of field devices and with minimal impact on communication performance on the field network.</p>
