Abstract:
The code-based post-quantum algorithm Hamming Quasi-Cyclic (HQC) is a fourth round candidate in the NIST standardization project. Since their third round version the authors utilize a new combination of error correcting codes, namely a combination of a Reed-Muller and a Reed-Solomon code, which requires an adaption of published attacks. We identify that the power side-channel attack by Uneo et al. from CHES 2021 does not work in practice as they miss the fact that the implemented Reed-Muller dec...     »
