WebAug 1, 2024 · ASCON cipher is an authenticated encryption with associated data (AEAD), based on sponge-like duplex construction [ 15 ]. The sponge construction is a simple iterated structure that maps a variable-length input to a variable-length output using fixed-length permutation. The fixed size of permutation function is called sponge state, …
