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…
