Impossible differential cryptanalysis using matrix method
Discrete Mathematics, 2009 AbstractThe general strategy of impossible differential cryptanalysis is to first find impossible differentials and then exploit them for retrieving subkey material from the outer rounds of block ciphers. Thus, impossible differentials are one of the crucial factors to see how much the underlying block ciphers are resistant to impossible differential ...

New Results in Reduced Round AES - 256 Impossible Differential Cryptanalysis [PDF]
International Journal of Computing and Digital Systems, 2020 : Security of Crypto systems is usually analyzed through different cryptanalytic methods. Since Advance Encryption Standard (AES) is one of the most widely used and popular block cipher, a number of attacks have already been proposed on it.

New Insights on Impossible Differential Cryptanalysis [PDF]
, 2012 Since its introduction, impossible differential cryptanalysis has been applied to many ciphers. Besides the specific application of the technique in various instances, there are some very basic results which apply to generic structures of ciphers, e.g., the well known 5-round impossible differential of Feistel ciphers with bijective round functions.

Impossible differential cryptanalysis of MARS‐like structures [PDF]
IET Information Security, 2014 The MARS-like structure is a generalised Feistel structure. Unified impossible differential (UID) method is an effective method to discover impossible differential characteristics for block cipher structures. In this study, for a specific kind of MARS-like structure, the authors use UID to show that when n, the number of subblocks, is even, there ...

Quantum impossible differential and truncated differential cryptanalysis
, 2017 Traditional cryptography is suffering a huge threat from the development of quantum computing. While many currently used public-key cryptosystems would be broken by Shor's algorithm, the effect of quantum computing on symmetric ones is still unclear. The security of symmetric ciphers relies heavily on the development of cryptanalytic tools.

Impossible Differential Cryptanalysis of Reduced-Round LBlock [PDF]
, 2012 In this paper, we improve the impossible differential attack on 20-round LBlock given in the design paper of the LBlock cipher. Using relations between the round keys we attack on 21-round and 22-round LBlock with a complexity of 269.5 and 279.28 encryptions respectively.

Impossible Differential Cryptanalysis on Lai-Massey Scheme [PDF]
ETRI Journal, 2014 The Lai-Massey scheme, proposed by Vaudenay, is a modified structure in the International Data Encryption Algorithm cipher. A family of block ciphers, named FOX, were built on the Lai-Massey scheme. Impossible differential cryptanalysis is a powerful technique used to recover the secret key of block ciphers.
