Modulation to the Rescue: Identifying Sub-Circuitry in the Transistor Morass for Targeted Analysis
Xhani Marvin Saß, Thilo Krachenfels, Frederik Dermot Pustelnik +3
Physical attacks form one of the most severe threats against secure computing platforms. Their criticality arises from their corresponding threat model: By, e.g., passively measuri…
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…
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…
Trojan Awakener: Detecting Dormant Malicious Hardware Using Laser Logic State Imaging (Extended Version)
Thilo Krachenfels, Jean-Pierre Seifert, Shahin Tajik
The threat of hardware Trojans (HTs) and their detection is a widely studied field. While the effort for inserting a Trojan into an application-specific integrated circuit (ASIC) c…
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…
Real-World Snapshots vs. Theory: Questioning the t-Probing Security Model
Thilo Krachenfels, Fatemeh Ganji, Amir Moradi +2
Due to its sound theoretical basis and practical efficiency, masking has become the most prominent countermeasure to protect cryptographic implementations against physical side-cha…
Evaluation of Low-Cost Thermal Laser Stimulation for Data Extraction and Key Readout
Thilo Krachenfels, Heiko Lohrke, Jean-Pierre Seifert +3
Recent attacks using thermal laser stimulation (TLS) have shown that it is possible to extract cryptographic keys from the battery-backed memory on state-of-the-art field-programma…
