Information leakage occurs when something about a system’s secret data can be deduced from observing its public outputs. In this talk, I will present a formal model of information leakage, based on discrete-time Markov chains, that models the information leaked about some secret data to an attacker with access to a program’s source code and public outputs. I will also present and demonstrate a practical implementation of this model that estimates (rather than precisely computes) information leakage in Java software, and will show that this implementation gives fast and accurate approximations of the true leakage that occurs in a program.
