This thesis focuses on the cybersecurity of embedded systems, particularly the vulnerability of processors and programs to fault injection attacks. These attacks disrupt the normal functioning of systems, allowing attackers to exploit weaknesses to access sensitive information. Although formal methods have been developed to analyze the robustness of systems, they often limit their analyses to hardware or software separately, overlooking the interaction between the two. The proposed work aims to formalize hardware/software (HW/SW) contracts specifically for security analysis against fault injection. Building on a hardware partitioning approach, this research seeks to mitigate scalability issues related to the complexity of microarchitecture models. Expected outcomes include the development of techniques and tools for effective security verification of embedded systems, as well as the creation of contracts that facilitate the assessment of compliance for both hardware and software implementations. This approach could also reduce the time-to-market for secure systems.
