From Multiplication to Recovery: A Single-trace Side-Channel Attack on HQC

Hamming Quasi-Cyclic (HQC) has been selected by NIST as a standard for code-based Post-Quantum Cryptography (PQC) Key Encapsulation Mechanisms (KEMs). While HQC offers robust theoretical security based on the Decisional Quasi- Cyclic Syndrome Decoding problem, its physical implementation is vulnerable to side-channel a...
