Enforcement and Validation (at runtime) of Various Notions of Opacity
Abstract
We are interested in the validation of opacity. Opacity models the impossibility for an attacker to retrieve the value of a secret in a system of interest. Roughly speaking, ensuring opacity provides confidentiality of a secret on the system that must not leak to an attacker. More specically, we study how we can model-check, verify and enforce at system runtime, several levels of opacity. Besides existing notions of opacity, we also introduce K-step strong opacity, a more practical notion of opacity that provides a stronger level of confidentiality.
