Conditional Cube Attack on Round-Reduced ASCON [PDF]
IACR Transactions on Symmetric Cryptology, 2017 This paper evaluates the secure level of authenticated encryption Ascon against cube-like method. Ascon submitted by Dobraunig et al. is one of 16 survivors of the 3rd round CAESAR competition. The cube-like method is first used by Dinur et al.
