Validity of Differential Characteristics of ARX Block Ciphers
In this paper, we examine the validity of the differential characteristics of ARX-based block ciphers. Recently, Peyrin et al. showed that some of the differential characteristics of block ciphers, SKINNY and GIFT, in the literature are not valid ...

Grover on Korean Block Ciphers
The Grover search algorithm reduces the security level of symmetric key cryptography with n-bit security level to O(2n/2). In order to evaluate the Grover search algorithm, the target block cipher should be efficiently implemented in quantum circuits ...

Iterative Block Ciphers from Tweakable Block Ciphers with Long Tweaks
We consider a problem of constructing a secure block cipher from a tweakable block cipher (TBC) with long tweaks. Given a TBC with n-bit blocks and Γn-bit tweaks for Γ ≥ 1, one of the constructions by Minematsu in DCC 2015 shows that a simple iteration ...

Probability distributions of correlation and differentials in block ciphers
We study the probability distributions of difference propagation probabilities and input-output correlations for functions and block ciphers of given dimensions, for several of them for the first time.

Provably Quantum-Secure Tweakable Block Ciphers
Recent results on quantum cryptanalysis show that some symmetric key schemes can be broken in polynomial time even if they are proven to be secure in the classical setting.

Efficient Implementation of PRESENT and GIFT on Quantum Computers
Grover search algorithm is the most representative quantum attack method that threatens the security of symmetric key cryptography. If the Grover search algorithm is applied to symmetric key cryptography, the security level of target symmetric key ...
