Two papers at PKC 2018

The year seems to end well, two of my papers got accepted for PKC 2018! The first paper presents rounded Gaussians as an alternative to discrete Gaussians in rejection sampling based lattice-based signature schemes (like BLISS). The advantage is that sampling from a rounded Gaussian can be easily done in constant time. The second paper is about SOFIA, a signature scheme with a security reduction from the MQ-problem in the quantum-accessible random oracle model. So far there was essentially only one signature scheme with a security reduction from the MQ-problem and this reduction was in the classical ROM.
