The design of Xoodoo and Xoofff
IACR Transactions on Symmetric Cryptology, 2018 This paper presents Xoodoo, a 48-byte cryptographic permutation with excellent propagation properties. Its design approach is inspired by Keccak-p, while it is dimensioned like Gimli for efficiency on low-end processors.

Differential-Linear Cryptanalysis of GIFT family and GIFT-based Ciphers
IACR Communications in CryptologyAt CHES 2017, Banik et al. proposed a lightweight block cipher GIFT consisting of two versions GIFT-64 and GIFT-128. Recently, there are lots of authenticated encryption schemes that adopt GIFT-128 as their underlying primitive, such as GIFT-COFB and HyENA.

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

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 :).

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 ...

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
