Chaire Cyber CNI – Cybersecurity for Critical Networked Infrastructures

Key Attack Strategies Against Black Box DNNs

At the 2022 IMT Atlantique research seminar, Yassine Hmamouche presented our joint works on “Key Attack Strategies Against Black Box DNNs”. This work happens in the frame of an intra-school collaboration project with Yehya Nasser and Amer Baghdadi of IMT Atlantique Brest that are experts on hardware security. For the chaire cyberCNI.fr this work is relevant as it complements our work on security of hardware systems coming form the software side.

The research seminar is a yearly event of IMT Atlantique where the school takes a resumée on past research activities and discusses on future research directions. This years edition took place in Rennes from 6.7.2022-7.7.2022.

Abstract

DNNs are enabling major advances in solving hard scientific problems and processing complex data on an unprecedented scale in many areas such as language processing, fraud detection, healthcare, and so on. The design of DNNs for commercial services requires a significant expenditure of time, money, and human effort, from collecting massive data to fine-tuning the model’s hyperparameters. Thus, the commercial value of these models makes them important intellectual property for companies, which incentivizes adversaries to mount specific attacks in order to retrieve their internal intelligence, gain knowledge about the sensitive information being processed by them, or at least disrupt their operation by intentionally injecting specific vulnerabilities. We believe that securing the software protocol and the physical layer stack is a fully functional solution for a secure platforms.

About the chair Cybersecurity of Critical Networked Infrastructures (cyberCNI.fr)

The Cyber CNI Chair at IMT Atlantique is devoted to research, innovation, and teaching in the field of the cybersecurity of critical infrastructures, including industrial processes, financial systems, building automation, energy networks, water treatment plants, transportation. The chair covers the full stack from sensors and actuators and their signals over industrial control systems, distributed services at the edge or cloud, to user interfaces with collaborative Mixed Reality, and security policies. The chair currently hosts 9 PhD students, 4 PostDocs, 11 Professors, 1+0.2 engineers, and 1 internship student.

The chair runs a large testbed that enables applied research together with the industry partners. The industry partners of the current third funding round are Airbus, Amossys, BNP Paribas, EDF, and SNCF. The chaire is located in Brittany, France. Brittany is the cybersecurity region number 1 in France. The chair Cyber CNI is strongly embedded in the cybersecurity ecosystem through its partnerships with the Pôle d’Excellence Cyber (PEC) and the Brittany Region. The chair provides a unique environment for cybersecurity research with lots of development possibilities.

About IMT Atlantique

We aim to put the scientific and technical excellence of IMT Atlantique at the service of education and innovation, to mobilize the expertise of our researchers in the fields of digital, energy and the environment. We endeavor to draw on our cutting-edge work, which is already influencing society and the business world, to train a new generation of engineers. But we can no longer innovate and develop new technologies without considering their ecological or societal impact. Those who embark on a career as an engineer must be aware of the role they will play in the future, the responsibilities they will have to assume, the ethical issues raised by technological developments, such as equipping humans with new faculties, relying on artificial intelligence, or evolving in an ultra-connected world.

Our mission at IMT Atlantique is to prepare the new generation to face future challenges, to deal with complex problems, to understand increasingly networked systems, but also and above all to be responsible agents for change in the world. By equipping our students with the best resources, we will help them develop an analytical mind and the ability to grow in an uncertain but exciting future, to be able to anticipate and accompany changes in society. The multi-dimensional crisis of the Covid-19 pandemic underscores the urgent need for this.

At IMT Atlantique, we are committed to training responsible engineers, that is to say engineers who are both ready to face the demands of a world that is changing at a sustained pace and committed to maintaining humanity and respect for life on a long-term basis.
