ABSTRACT
Industrial control system (ICS) and critical infrastructure have become increasingly dependent on cyber-physical systems nowadays. Since ICS network is vulnerable to adversarial attacks, building secure operation mode is essential. In order to secure the integrity of data in ICS, this paper proposes a blockchain-based log system implemented on physical industrial equipment. Applying cross-organizational blockchain transaction mechanism in the specialized master-slave network model, industrial control transmission logs can be verified and non-repudiation
