Bonjour,
La prochaine session du séminaire sécurité des systèmes électroniques embarqués aura lieu le vendredi 23 Mai de 10h à 12h.
Le séminaire aura lieu dans les locaux de l'IRISA Rennes, Salle Aurigny.
Le programme de cette session est le suivant :
- 10:00 - 11:00 - Cler GAUTHIER (SERMA Safety & Security)
- Titre : Anomalies Mitigation for Horizontal Side Channel Attacks with Unsupervised Neural Networks
- Résumé : The success of horizontal side-channel attacks heavily depends on the quality of the traces as well as the correct extraction of interest areas, which are expected to contain relevant leakages. If former is insufficient, this will consequently degrade the identification capability of potential leakage candidates and often render attacks inapplicable. This work assess the relevance of neural networks in the unsupervised context of horizontal attacks to mitigate noise artefacts from the input signal by proposing two methods with alternative training objectives. Their application results in enhanced traces quality and better exploitability using clustering-based horizontal attacks.
- 11:00 - 12:00 - Benoit COQUERET (INRIA, Thales CESTI)
- Titre : Cryptanalytical extraction of complex Neural Networks in black-box settings
- Résumé : With the widespread development of artifical intelligence, Deep Neural Networks (DNN) have become valuable intellectual property (IP). In the past few years, software and hardware-based attacks targetting at the weights of the DNN have been introduced allowing potential attacker to gain access to a near-perfect copy of the victim's model. However, these attacks either fail against more complex architecture or loose in fidelity regarding the targeted model. In this talk, I will present a new attack methodology combining side-channels attacks with software attacks in order to extract more complex DNN. First, I will present the main methodologies from the state of the art, and the comparison that can be made with traditional cryptanalytic attacks. I will then describe how side-channel attacks can help with the current limitations and introduce our framework as well as our experimental results. This talk will be concluded by the presentation of some potentials future work.
