Extended Generalized Feistel Networks using Matrix Representation [PDF]
, 2013 International audienceWhile Generalized Feistel Networks have been widely studied in the literature as a building block of a block cipher, we propose in this paper a unified vision to easily represent them through a matrix representation. We then propose

Comprehensive security analysis of CRAFT
IACR Transactions on Symmetric Cryptology, 2020 CRAFT is a lightweight block cipher, designed to provide efficient protection against differential fault attacks. It is a tweakable cipher that includes 32 rounds to produce a ciphertext from a 64-bit plaintext using a 128-bit key and 64-bit public tweak.

Key Committing Security of AEZ and More
IACR Transactions on Symmetric Cryptology, 2023 For an Authenticated Encryption with Associated Data (AEAD) scheme, the key committing security refers to the security notion of whether the adversary can produce a pair of distinct input tuples, including the key, that result in the same output.

IACR Transactions on Symmetric Cryptology, 2017 CAESAR has caused a heated discussion regarding the merits of one-pass encryption and online ciphers. The latter is a keyed, length preserving function which outputs ciphertext blocks as soon as the respective plaintext block is available as input.

MergeMAC:A MAC for Authentication with Strict Time Constraints and Limited Bandwidth [PDF]
, 2018 This paper presents MergeMAC, a MAC that is particularly suitable for environments with strict time requirements and extremely limited bandwidth. MergeMAC computes the MAC by splitting the message into two parts.

A General Construction of Tweakable Block Ciphers and Different Modes of Operations [PDF]
IEEE Transactions on Information Theory, 2006 This work builds on earlier work by Rogaway at Asiacrypt 2004 on tweakable block cipher (TBC) and modes of operations. Our first contribution is to generalize Rogaway's TBC construction by working over a ring and by the use of a masking sequence of functions. The ring can be instantiated as either GF or as .

Key‐dependent side‐channel cube attack on CRAFT
ETRI Journal, 2021 CRAFT is a tweakable block cipher introduced in 2019 that aims to provide strong protection against differential fault analysis. In this paper, we show that CRAFT is vulnerable to side‐channel cube attacks.

XHX - A Framework for Optimally Secure Tweakable Block Ciphers from Classical Block Ciphers and Universal Hashing [PDF]
, 2021 Tweakable block ciphers are important primitives for designing cryptographic schemes with high security. In the absence of a standardized tweakable block cipher, constructions built from classical block ciphers remain an interesting research topic in ...
