This repository contain an implementation of multiple AEAD algorithms with side-channel countermeasures:
These implementations have been designed for algorithm comparison purpose only and have not been practically evaluated.
Except for Romulus-N, the implementations are leveled: some primitives are masked (using the HPC2 masking scheme), while others are not masked.
The designs have been tested with iverilog (version 10.3). From the "sim" folder, all ciphers can be simulated (with iverilog) and displayed (with GTKWave) with the following command:
