The objective of SEARCH (2019–2022) is to develop methods and tools for assessing technical design solutions related to overall instrumentation and control (I&C) system architectures. A particular focus is on trade-offs between requirements related to safety, dependability and security. We also aim to broaden the scope in which formal methods can effectively be used to verify properties on how the I&C systems operate as a whole. In the first two project years, SEARCH has developed models and methods for early hybrid assessment of safety and security of overall I&C architectures. In addition, we have further developed methods of performing software model checking, accounting for hardware failures and communication delay. We have also developed a practical tool for explaining counterexamples.
