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…

Obelix: Mitigating Side-Channels Through Dynamic Obfuscation
Jan Wichelmann, Anja Rabich, Anna P"atschke +1
Trusted execution environments (TEEs) offer hardware-assisted means to protect code and data. However, as shown in numerous results over the years, attackers can use side-channels…

Zebrafix: Mitigating Memory-Centric Side-Channel Leakage via Interleaving
Anna Pätschke, Jan Wichelmann, Thomas Eisenbarth
Constant-time code has become the de-facto standard for secure cryptographic implementations. However, some memory-based leakage classes such as ciphertext side-channels and silent…
