Maskaglia: A New, Efficient Approach to Masked Discrete Gaussian Sampling

Discrete Gaussian sampling is an important operation at the core of many lattice-based cryptosystems, which presents significant challenges from an implementation standpoint. In particular, it is difficult to protect against side-channel attacks. Extensive research has gone into the problem of addressing timing side-channel attacks, and as result, constant-time discrete Gaussian sampling is now well-understood. However,Read More
