Formally-verified Security against Forgery of Remote Attestation using SSProve [PDF]
arXivRemote attestation (RA) is the foundation for trusted execution environments in the cloud and trusted device driver onboarding in operating systems. However, RA misses a rigorous mechanized definition of its security properties in one of the strongest models, i.e., the semantic model. Such a mechanization requires the concept of State-Separating Proofs
