AEX-NStep: Probabilistic Interrupt Counting Attacks on Intel SGX
Nicolas Dutly, Friederike Groschupp, Ivan Puddu +2
To mitigate interrupt-based stepping attacks (notably using SGX-Step), Intel introduced AEX-Notify, an ISA extension to Intel SGX that aims to prevent deterministic single-stepping…
Breaking Bad: How Compilers Break Constant-Time Implementations
Moritz Schneider, Daniele Lain, Ivan Puddu +2
The implementations of most hardened cryptographic libraries use defensive programming techniques for side-channel resistance. These techniques are usually specified as guidelines…
Sovereign Smartphone: To Enjoy Freedom We Have to Control Our Phones
Friederike Groschupp, Moritz Schneider, Ivan Puddu +2
The majority of smartphones either run iOS or Android operating systems. This has created two distinct ecosystems largely controlled by Apple and Google - they dictate which applic…
I Send, Therefore I Leak: Information Leakage in Low-Power Wide Area Networks
Patrick Leu, Ivan Puddu, Aanjhan Ranganathan +1
Low-power wide area networks (LPWANs), such as LoRa, are fast emerging as the preferred networking technology for large-scale Internet of Things deployments (e.g., smart cities). D…
TEEvil: Identity Lease via Trusted Execution Environments
Ivan Puddu, Daniele Lain, Moritz Schneider +3
We investigate identity lease, a new type of service in which users lease their identities to third parties by providing them with full or restricted access to their online account…
Dataplant: Enhancing System Security with Low-Cost In-DRAM Value Generation Primitives
Lois Orosa, Yaohua Wang, Ivan Puddu +13
DRAM manufacturers have been prioritizing memory capacity, yield, and bandwidth for years, while trying to keep the design complexity as simple as possible. DRAM chips do not carry…
