Smart contracts enable users to execute payments depending on complex program logic. Ethereum is the most notable example of a blockchain that supports smart contracts leveraged fo…
Offline Model Guard: Secure and Private ML on Mobile Devices
Sebastian P. Bayerl, Tommaso Frassetto, Patrick Jauernig +5
Performing machine learning tasks in mobile applications yields a challenging conflict of interest: highly sensitive client information (e.g., speech data) should remain private wh…
V0LTpwn: Attacking x86 Processor Integrity from Software
Zijo Kenjar, Tommaso Frassetto, David Gens +2
Fault-injection attacks have been proven in the past to be a reliable way of bypassing hardware-based security measures, such as cryptographic hashes, privilege and access permissi…
HybCache: Hybrid Side-Channel-Resilient Caches for Trusted Execution Environments
Ghada Dessouky, Tommaso Frassetto, Ahmad-Reza Sadeghi
Modern multi-core processors share cache resources for maximum cache utilization and performance gains. However, this leaves the cache vulnerable to side-channel attacks, where tim…
DR.SGX: Hardening SGX Enclaves against Cache Attacks with Data Location Randomization
Ferdinand Brasser, Srdjan Capkun, Alexandra Dmitrienko +3
Recent research has demonstrated that Intel's SGX is vulnerable to software-based side-channel attacks. In a common attack, the adversary monitors CPU caches to infer secret-depend…
