New Conditional Cube Attack on Keccak Keyed Modes [PDF]
IACR Transactions on Symmetric Cryptology, 2019 The conditional cube attack on round-reduced Keccak keyed modes was proposed by Huang et al. at EUROCRYPT 2017. In their attack, a conditional cube variable was introduced, whose diffusion was significantly reduced by certain key bit conditions.

Conditional Cube Attack on Round-Reduced ASCON
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.

Conditional Cube Key Recovery Attack on Round-Reduced Xoodyak [PDF]
Lecture Notes in Computer Science, 2023 Since the announcement of the NIST call for a new lightweight cryptographic standard, a lot of schemes have been proposed in response. Xoodyak is one of these schemes and is among the finalists of the NIST competition with a sponge structure very similar to the Keccak hash function – the winner of the SHA3 NIST competition.

Resistance of Ascon Family Against Conditional Cube Attacks in Nonce-Misuse Setting
IEEE Access, 2023 Ascon family is one of the finalists of the National Institute of Standards and Technology (NIST) lightweight cryptography standardization process. The family includes three Authenticated Encryption with Associated Data (AEAD) schemes: Ascon-128 (primary)

Improved Conditional Cube Attacks on Ascon AEADs in Nonce-Respecting Settings
IACR Transactions on Symmetric CryptologyThe best-known distinguisher on 7-round Ascon-128 and Ascon-128a AEAD uses a 60-dimensional cube where the nonce bits are set to be equal in the third and fourth rows of the Ascon state during initialization (Rohit et al. ToSC 2021/1).

Cube Attacks with Elimination Strategy: Key Recovery Attacks on Trivium
IACR Transactions on Symmetric CryptologyIn this paper, we present a novel framework for cube attacks named cube attacks with elimination strategy. The core idea is to find specific key conditions and cubes such that their superpolies under these key conditions can be efficiently computed.
