Multiple Impossible Differentials Attack on AES-192 [PDF]
IEEE Access, 2019 The security of AES-192 against multiple impossible differentials attack is studied in this paper. Based on two types of impossible differentials for 4-round AES, two 7-round attack trails of AES-192 with the same plaintext and ciphertext difference ...

Accurate Estimate of the Advantage of Impossible Differential Attacks
IACR Transactions on Symmetric Cryptology, 2017 Impossible differential attacks, which are taking advantage of differentials that cannot occur, are powerful attacks for block cipher primitives. The power of such attacks is often measured in terms of the advantage — number of key-bits found during the ...

MILP-Aided Related-Tweak/Key Impossible Differential Attack and its Applications to QARMA, Joltik-BC
IEEE Access, 2019 In this paper, we study the relation of related-tweak/key impossible differentials with single-key ones. Following a heuristic strategy, we can derive longer related-tweak/key impossible differentials from single-key ones. We implement this strategy with

General Impossible Differential Attack on 7-Round AES
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2010 Impossible differential attack (IDA) uses impossible differential characteristics extracted from enough plaintext pairs to retrieve subkeys of the first and the last several rounds of AES. In this paper, a general IDA on 7-round AES is proposed. Such attack takes the number of all-zero columns of the 7th and the 6th round as parameters (α, β).

Square impossible differential attack and security of AES in known plaintext scenario
CryptologiaIn this work, we examine the security of the 8-round AES, under the known plaintext attack scenario, a type of cryptographic attack in which an attacker has access to the plaintext and corresponding ciphertext pairs. We present an innovative impossible differential (ID) attack technique, which utilizes a specific ID characteristic, to perform the first
