EM-Fault It Yourself: Building a Replicable EMFI Setup for Desktop and Server Hardware
Niclas Kühnapfel, Robert Buhren, Hans Niklas Jacob +3
EMFI has become a popular fault injection (FI) technique due to its ability to inject faults precisely considering timing and location. Recently, ARM, RISC-V, and even x86 processi…
Learnability of the output distributions of local quantum circuits
Marcel Hinsche, Marios Ioannou, Alexander Nietner +6
There is currently a large interest in understanding the potential advantages quantum devices can offer for probabilistic modelling. In this work we investigate, within two differe…
VIA: Analyzing Device Interfaces of Protected Virtual Machines
Felicitas Hetzelt, Martin Radev, Robert Buhren +2
Both AMD and Intel have presented technologies for confidential computing in cloud environments. The proposed solutions - AMD SEV (-ES, -SNP) and Intel TDX - protect Virtual Machin…
One Glitch to Rule Them All: Fault Injection Attacks Against AMD's Secure Encrypted Virtualization
Robert Buhren, Hans Niklas Jacob, Thilo Krachenfels +1
AMD Secure Encrypted Virtualization (SEV) offers protection mechanisms for virtual machines in untrusted environments through memory and register encryption. To separate security-s…
The Forgotten Threat of Voltage Glitching: A Case Study on Nvidia Tegra X2 SoCs
Otto Bittner, Thilo Krachenfels, Andreas Galauner +1
Voltage fault injection (FI) is a well-known attack technique that can be used to force faulty behavior in processors during their operation. Glitching the supply voltage can cause…
Automatic Extraction of Secrets from the Transistor Jungle using Laser-Assisted Side-Channel Attacks
Thilo Krachenfels, Tuba Kiyan, Shahin Tajik +1
The security of modern electronic devices relies on secret keys stored on secure hardware modules as the root-of-trust (RoT). Extracting those keys would break the security of the…
