WCFB: a tweakable wide block cipher [PDF]
IACR Cryptol. ePrint Arch., 2014 We define a model for applications that process large data sets in a way that enables additional optimizations of encryption operations. We designed a new strong pseudo-random tweakable permutation, WCFB, to take advantage of identified characteristics ...

MATTER: A Wide-Block Tweakable Block Cipher [PDF]
IACR Cryptol. ePrint Arch.In this note, we introduce the MATTER Tweakable Block Cipher, designed principally for low latency in low-area hardware implementations, but that can also be implemented in an efficient and compact way in software.

Tweaking a block cipher: multi-user beyond-birthday-bound security in the standard model [PDF]
, 2018 peer reviewedIn this paper, we present a generic construction to create a secure tweakable block cipher from a secure block cipher. Our construction is very natural, requiring four calls to the underlying block cipher for each call of the tweakable block

CRAFT: Lightweight Tweakable Block Cipher with Efficient Protection Against DFA Attacks [PDF]
IACR Transactions on Symmetric Cryptology, 2019 Traditionally, countermeasures against physical attacks are integrated into the implementation of cryptographic primitives after the algorithms have been designed for achieving a certain level of cryptanalytic security.

IACR Transactions on Symmetric Cryptology, 2021 In this work, we propose a construction of 2-round tweakable substitutionpermutation networks using a single secret S-box. This construction is based on non-linear permutation layers using independent round keys, and achieves security beyond the birthday

Cascading Four Round LRW1 is Beyond Birthday Bound Secure
IACR Transactions on Symmetric Cryptology, 2023 In CRYPTO’02, Liskov et al. introduced the concept of a tweakable block cipher, a novel symmetric key primitive with promising applications. They put forth two constructions for designing such tweakable block ciphers from conventional block ciphers ...

1, 2, 3, Fork: Counter Mode Variants based on a Generalized Forkcipher
IACR Transactions on Symmetric Cryptology, 2021 A multi-forkcipher (MFC) is a generalization of the forkcipher (FC) primitive introduced by Andreeva et al. at ASIACRYPT’19. An MFC is a tweakable cipher that computes s output blocks for a single input block, with s arbitrary but fixed.
