Critical Systems under Cyber Threats

Abstract

Cybersecurity of digital critical systems, such as nuclear reactors, is a research area of great interest at present. As a result, novel methods of attack resiliency are being explored to support diverse and redundant Cyber Physical Systems. By exploiting the time dependent nature of common control units, the physical operability of the overall structure is enhanced, resulting in greater security and reliability. An important concern is the stability and integrity of the system through cyber support. This stability is created through the introduction of the proposed architecture, which places a premium on the continuation of known quality signal.
