libqif - A Quantitative Information Flow C++ Toolkit Library
Keywords: Information leakage - Privacy - C++ - Linear optimization
Functional Description: The goal of libqif is to provide an efficient C++ toolkit implementing a variety of techniques and algorithms from the area of quantitative information flow and differential privacy. We plan to implement all techniques produced by Comète in recent years, as well as several ones produced outside the group, giving the ability to privacy researchers to reproduce our results and compare different techniques in a uniform and efficient framework.
Some of these techniques were previously implemented in an ad-hoc fashion, in small, incompatible with each-other, non-maintained and usually inefficient tools, used only for the purposes of a single paper and then abandoned. We aim at reimplementing those – as well as adding several new ones not previously implemented – in a structured, efficient and maintainable manner, providing a tool of great value for future research. Of particular interest is the ability to easily re-run evaluations, experiments and case-studies from all our papers, which will be of great value for comparing new research results in the future.
The library's development continued in 2017 with several new added features. The project's git repository shows for this year 33 commits by 2 contributors. The new functionality was directly applied to the exeperimental results of several publications of the team (PETS'17, GameSec'17, VALUETOOLS'17).
