Description
Hardware Trojan Horses that are software-exploitable can be inserted into microprocessors, allowing attackers to run unauthorized code or escalate privileges. Additionally, it has been demonstrated that attackers could observe certain microprocessor features - seemingly unrelated to the program's execution - to exfiltrate secrets or private data. So, even devices produced in secure foundries could be vulnerable to such attacks. A promising defense strategy involves implementing Hardware Security Modules that monitor the runtime behavior of microprocessors to detect ongoing attacks. But why do we need Hardware Security Modules? Are software-based solutions not sufficient? Hardware Security Modules are essential because if attackers manage to execute malicious code, they could bypass or disable software defenses, leading to privilege escalation and other serious consequences. In contrast, hardware-based countermeasures raise the bar significantly, as modifying fabricated chips is far more difficult than compromising software, making Hardware Security Module implementations a more robust and resilient defense mechanism.

Sécurité physique du mécanisme d'encapsulation de clé Classic McEliece
Speaker : Brice Colombier - Laboratoire Hubert Curien, Université Jean Monnet, Saint-Étienne
Le mécanisme d'encapsulation de clé Classic McEliece faisait partie des candidats toujours en lice au dernier tour du processus de standardisation de la cryptographie post-quantique initié par le NIST en 2016. Fondé sur les codes correcteurs d'erreurs, en particulier autour du cryptosystème de Niederreiter, sa sécurité n'a pas été fondamentalement remise en cause. Néanmoins, un aspect important du[…]-
