Quantitative Information Flow as Safety and Liveness Hyperproperties
Hirotoshi Yasuoka, Tachio Terauchi · Electronic Proceedings in Theoretical Computer Science · 2012
We employ Clarkson and Schneider's "hyperproperties" to classify various verification problems of quantitative information flow. The results of this paper unify and extend the previous results on the hardness of checking and inferring quantitative information flow. In particular, we identify a subclass of liveness hyperproperties, which we call "k-observable hyperproperties", that can be checked relative to a reachability oracle via self composition.
