In this thesis, we consider a class of security enforcement mechanismswe called
Hardware-based Security Enforcement (HSE). In such mechanisms,some trusted
software components rely on the underlying hardware architecture to constrain
the execution of untrusted software components with respect to targeted security
policies. For instance, an operatingsystem which configures page tables to
isolate userland applicationsimplements a HSE mechanism.
During the past decades, several vulnerability disclosures have defeated HSE
mechanisms. We focus on vulnerabilities that are the result of errors at
the specification level, rather than implementation errors. Our goal is to
explore approaches to specify and verify HSE mechanisms using formal methods
that would benefit both hardware designers and software developers. Firstly, a
formal specification of HSE mechanismscan be leveraged as a foundation for a
systematic approach to verifyhardware specifications, in the hope of uncovering
potential compositional attacks ahead of time. Secondly, it provides
unambiguous specifications to software developers, in the form of a list
