Lattice‐based hash‐and‐sign signatures using approximate trapdoor, revisited
Abstract For the purpose of improving the efficiency of the cryptosystems built upon lattice trapdoors, Chen, Genise and Mukherjee at ASIACRYPT 2019 modified the gadget trapdoor (G‐trapdoor) to an approximate trapdoor, which enables one to sample short preimages approximately from a discrete Gaussia...
