Revisiting Keccak and Dilithium Implementations on ARMv7-M

Transactions on Cryptographic Hardware and Embedded Systems
Keccak is widely used in lattice-based cryptography (LBC) and its impact to the overall running time in LBC scheme can be predominant on platforms lacking dedicated SHA-3 instructions. This holds true on embedded devices for Kyber and Dilithium, two LBC
