In this work, we present various hardware implementation for ASCON. We cover encryption + tag generation as well as decryption + tag verification for ASCON AEAD and also ASCON hash function. On top the usual (unprotected) implementation, we present side channel protection (threshold countermeasure) and triplication/majority based fault protection. The side channel and fault protections work orthogonal to each other (i.e., either one can be turned on/off without affecting the other). We also show ASIC and FPGA benchmarks for our implementations.
