Developing Blockchain-based Cyber Security Techniques in Nuclear Power Plants
A digital Instrument and Control (I&C) system has been developed and installed in nuclear power plants, and due to installation of the digital I&C systems, Cyber security concerns are increasing in nuclear industry. In this paper, cyber threats of I&C system were analyzed in aspect of system confidentiality, integrity and availability (CIA). Since Cyber security for all digital assets is not practically feasible, Critical Digital Assets (CDA) directly related to the safety of Nuclear Power Plants(NPPs) were selected using the probabilistic risk assessment. We propose a new Blockchain-based security method for CDA. It is expected that Cyber security for CIA of I&C system would be enhanced through adopting Blockchain technology.
