Improved Differential-Linear Cryptanalysis of 7-Round Chaskey with Partitioning [PDF]

, 2016
In this work we study the security of Chaskey, a recent lightweight MAC designed by Mouha et al., currently being considered for standardization by ISO/IEC and ITU-T. Chaskey uses an ARX structure very similar to SipHash. We present the first cryptanalysis of Chaskey in the single user setting, with a differential-linear attack against 6 and 7 rounds ...

Multiple differential-zero correlation linear cryptanalysis of reduced-round CAST-256

Journal of Mathematical Cryptology, 2017
CAST-256 (or CAST6) is a symmetric-key block cipher published in June 1998. It was submitted as a candidate for Advanced Encryption Standard (AES). In this paper, we will propose a new chosen text attack, the multiple differential-zero correlation linear

Subspace Trail Cryptanalysis and its Applications to AES

IACR Transactions on Symmetric Cryptology, 2017
We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

ESTABLISHED WAYS TO ATTACK EVEN THE BEST ENCRYPTION ALGORITHM [PDF]

Which solution is the best – public key or private key encryption? This question cannot have a very rigorous, logical and definitive answer, so that the matter be forever settled :).

DIFFERENTIAL AND LINEAR CRYPTOANALYSIS METHODS ELEMENTS FOR ENCRYPTION ALGORITHM BASED ON DYNAMIC CHAOS

Системный анализ и прикладная информатика, 2015
In this paper we assessed the sustainability of the encryption algorithm based on dynamic chaos, as well as the basic principles for the implementation of linear and differential cryptanalysis.

Rigorous upper bounds on data complexities of block cipher cryptanalysis

Journal of Mathematical Cryptology, 2017
Statistical analysis of symmetric key attacks aims to obtain an expression for the data complexity which is the number of plaintext-ciphertext pairs needed to achieve the parameters of the attack. Existing statistical analyses invariably use some kind of
