We extend definitions of information flow so as to quantify the amount of information passed; in other words, we give a formal definition of the capacity of covert channels. Ou...
Deeply embedded infrastructures are pervasive systems that have significant cyber and physical components, interacting with each other in complex ways. These interactions can vio...
—In this paper, we investigate the computational complexity of quantitative information flow (QIF) problems. Information-theoretic quantitative relaxations of noninterference (b...
Tracking information flow in dynamic languages remains an open challenge. It might seem natural to address the challenge by runtime monitoring. However, there are well-known funda...
The termination insensitive secure information flow problem can be reduced to solving a safety problem via a simple program transformation. Barthe, D’Argenio, and Rezk coined th...
