The lattice-based CRYSTALS-Dilithium signature schemes has been selected for standardization by the NIST. As part of the selection process, a large number of implementations for platforms like x86, ARM Cortex-M4, or - on the hardware side - Xilinx Artix-7 have been presented and discussed by experts. Moreover, the software implementations have been subject to side-channel analysis with several attacks …
