2010 Seventh International Conference on the Quantitative Evaluation of Systems, 2010 Opacity is a general language-theoretic framework in which several security properties of a system can be expressed. Its parameters are a predicate, given as a subset of runs of the system, and an observation function, from the set of runs into a set of observables.
