Collision Attacks on AES-192/256, Crypton-192/256, mCrypton-96/128, and Anubis
Journal of Applied Mathematics, 2013 At AES’00, a collision attack on 7-round reduced AES was proposed. In this paper, we apply this idea to seven SPN block ciphers, AES-192/256, Crypton-192/256, mCrypton-96/128, and Anubis.

Preimage Attacks on Some Hashing Modes Instantiating Reduced-Round LBlock
IEEE Access, 2018 In this paper, we present preimage attacks on several hashing modes instantiating reduced-round LBlock. It is observed that the omission of the network twist in the last round and the diffusion of the permutation in round function are the key points for ...

Partly-Pseudo-Linear Cryptanalysis of Reduced-Round Speck
Cryptography, 2020 We apply McKay’s pseudo-linear approximation of addition modular 2n to lightweight ARX block ciphers with large words, specifically the Speck family. We demonstrate that a pseudo-linear approximation can be combined with a linear approximation using the ...

On the Design of Secure and Fast Double Block Length Hash Functions [PDF]
, 2008 In this work the security of the rate-1 double block length hash functions, which based on a block cipher with a block length of n-bit and a key length of 2n-bit, is reconsidered.

Improved Integral Attack on Reduced-Round Simeck
IEEE Access, 2019 Simeck, a family of lightweight block ciphers utilizing Simon-like structure, is widely used under resource constrained environment. So far, many cryptanalysis methods have been used to attack Simeck.

Cryptanalysis of AES-PRF and Its Dual
IACR Transactions on Symmetric Cryptology, 2018 A dedicated pseudorandom function (PRF) called AES-PRF was proposed by Mennink and Neves at FSE 2018 (ToSC 2017, Issue 3). AES-PRF is obtained from AES by using the output of the 5-th round as the feed-forward to the output state.

Security Amplification against Meet-in-the-Middle Attacks Using Whitening [PDF]
, 2013 In this paper we introduce a model for studying meet-in-the-middle attacks on block ci-phers, and a simple block cipher construction provably resistant to such attacks in this model. A side-result of this is a proper formalization for an unproven alternative to DESX proposed by Kilian and Rogaway; this construction can now be shown to be sound in our ...
