Iterative Block Ciphers from Tweakable Block Ciphers with Long Tweaks
IACR Transactions on Symmetric Cryptology, 2020 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 ...

Validity of Differential Characteristics of ARX Block Ciphers
IEEE Access, 2023 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 ...

Provably Quantum-Secure Tweakable Block Ciphers
IACR Transactions on Symmetric Cryptology, 2021 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.

COUNTER MODE DEVELOPMENT FOR BLOCK CIPHER OPERATIONS [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 There are two basic types of symmetric cipher: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer. Stream ciphers operate on streams of plaintext and ciphertext one bit or
