HPCCFA: Leveraging Hardware Performance Counters for Control Flow Attestation
Claudius Pott, Luca Wilke, Jan Wichelmann +1
Trusted Execution Environments (TEEs) allow the secure execution of code on remote systems without the need to trust their operators. They use static attestation as a central mecha…
SLasH-DSA: Breaking SLH-DSA Using an Extensible End-To-End Rowhammer Framework
Jeremy Boy, Antoon Purnal, Anna Pätschke +2
As quantum computing advances, Post-Quantum Cryptography (PQC) schemes are adopted to replace classical algorithms. Among them is the Stateless Hash-Based Digital Signature Algorit…
SNPGuard: Remote Attestation of SEV-SNP VMs Using Open Source Tools
Luca Wilke, Gianluca Scopelliti
Cloud computing is a ubiquitous solution to handle today's complex computing demands. However, it comes with data privacy concerns, as the cloud service provider has complete acces…
SEV-Step: A Single-Stepping Framework for AMD-SEV
Luca Wilke, Jan Wichelmann, Anja Rabich +1
The ever increasing popularity and availability of Trusted Execution Environments (TEEs) had a stark influence on microarchitectural attack research in academia, as their strong at…
Cipherfix: Mitigating Ciphertext Side-Channel Attacks in Software
Jan Wichelmann, Anna Pätschke, Luca Wilke +1
Trusted execution environments (TEEs) provide an environment for running workloads in the cloud without having to trust cloud service providers, by offering additional hardware-ass…
undeSErVed trust: Exploiting Permutation-Agnostic Remote Attestation
Luca Wilke, Jan Wichelmann, Florian Sieck +1
The ongoing trend of moving data and computation to the cloud is met with concerns regarding privacy and protection of intellectual property. Cloud Service Providers (CSP) must be…
SEVurity: No Security Without Integrity -- Breaking Integrity-Free Memory Encryption with Minimal Assumptions
Luca Wilke, Jan Wichelmann, Mathias Morbitzer +1
One reason for not adopting cloud services is the required trust in the cloud provider: As they control the hypervisor, any data processed in the system is accessible to them. Full…
