Crate fbleau[][src]

F-BLEAU is a tool for estimating the leakage of a system about its secrets in a black-box manner (i.e., by only looking at examples of secret inputs and respective outputs). It considers a generic system as a black-box, taking secret inputs and returning outputs accordingly, and it measures how much the outputs "leak" about the inputs.

F-BLEAU is based on the equivalence between estimating the error of a Machine Learning model of a specific class and the estimation of information leakage [1,2,3].

This code was also used for the experiments of [2] on the following evaluations: Gowalla, e-passport, and side channel attack to finite field exponentiation.

Getting started

F-BLEAU is thought to be mainly used via the binary it provides, fbleau. For usage instructions, please refer to fbleau's home page or to the help screen: fbleau -h.
