Machine-Learning Side-Channel Attacks on the GALACTICS Constant-Time Implementation of BLISS. (arXiv:2109.09461v3 [cs.CR] UPDATED)

Due to the advancing development of quantum computers, practical attacks on
conventional public-key cryptography may become feasible in the next few
decades. To address this risk, post-quantum schemes that are secure against
quantum attacks are being developed.

Lattice-based algorithms are promising replacements for conventional schemes,
with BLISS being one of the earliest post-quantum signature schemes in this
family. However, required subroutines such as Gaussian sampling have been
demonstrated to be a risk for the security of BLISS, since implementing
Gaussian …
