Automatized high-level evaluation of security properties for RTL hardware designs

Abstract

The ever increasing integration of embedded systems into our every lives created a strong demand for trustable software and hardware implementations. To provide such trust between manufacturer and customer of integrated systems, regulatory rules like the Common Criteria have been defined. While this international standard clearly prescribes the usage of formal methods at high assurance level, formal verification at code-level is not widespread in practice.This work introduces a novel approach to verify the correct functionality of security critical hardware implementations under fault conditions. Generality is enabled by high-level evaluation using state machines extracted in an automatized way.
