Game Theory for Nuclear Power Plant Cyber-Attack Response and Cyber-Security Risk Assessment
All dates for this event occur in the past.
Yunfei Zhao, Ph.D., Research Associate, The Ohio State University
ABSTRACT:
Digital systems have been increasingly used in nuclear power plants. This improves the efficiency of nuclear energy but also raises concerns about cyber-security. To improve the cyber-security posture of nuclear energy, it is important to develop effective methods for cyber-attack detection, cyber-attack response, and cyber-security risk assessment. Compared with regular events, for example, those caused by pure hardware failures, the presence of malicious attackers in cyber-attacks significantly increases the complexity of the problem. This is because the evolution and consequence of a cyber-security event depend not only on actions taken by plant operators, but also on actions taken by the attackers. Game theory provides a suitable technique to study the interaction among multiple players. In this seminar, the speaker will discuss how game theory can be applied to nuclear power plant cyber-attack response modeling and real-time cyber-security risk update.
