“…Security Verification can be used to detect certain types of HTs. It works by deriving formal security models for hardware designs and prove security properties such as confidentiality and integrity through formal approaches, e.g., SAT solving, model checking and type checking [222]- [224]. A security property violation indicates the existence of unintentional design flaw or intended malicious design modification.…”

“…The limitations of code/structural analysis techniques are that they do not guarantee Trojan detection, and manual postprocessing is required to analyze suspicious signals or gates and determine if they are a part of a Trojan. -Formal verification is an algorithmic-based approach to logic verification that exhaustively proves a predefined set of security properties that a design should satisfy [Zhang and Tehranipoor 2011a;Rathmair et al 2014;Rajendran et al 2015]. To check if a design honors these properties, one converts the target design into a proofchecking format (e.g., Coq) [Love et al 2011].…”

Given the increasing complexity of modern electronics and the cost of fabrication, entities from around the globe have become more heavily involved in all phases of the electronics supply chain. In this environment, hardware Trojans (i.e., malicious modifications or inclusions made by untrusted third parties) pose major security concerns, especially for those integrated circuits (ICs) and systems used in critical applications and cyber infrastructure. While hardware Trojans have been explored significantly in academia over the last decade, there remains room for improvement. In this article, we examine the research on hardware Trojans from the last decade and attempt to capture the lessons learned. A comprehensive adversarial model taxonomy is introduced and used to examine the current state of the art. Then the past countermeasures and publication trends are categorized based on the adversarial model and topic. Through this analysis, we identify what has been covered and the important problems that are underinvestigated. We also identify the most critical lessons for those new to the field and suggest a roadmap for future hardware Trojan research.

Formal verification of business process models can be done through model checking (also known as property checking), where a model checker tool may automatically find violations of properties in a process model. This approach obviously has formal representations as a prerequisite. However, a key challenge for applying this approach in practice is to consistently formalize the process and its properties, which clearly cannot be done automatically. We studied this challenge in a case study of formally verifying an informally given business process against a guideline written like a legal text. Major lessons learned from this case study are that formalizing is key to success and that in its course a semi-formal representation of properties is useful. In the course of such a step-wise and incremental formalization, problems with the given process model have been found already, apart from those found with a model checker tool that used the formal property specification. In total, our approach revealed five problems not found by the official review. In summary, this paper investigates in a case study consistently formalizing a business process and its properties for verification through model checking.
