Almost-Minimal-Round BBB-Secure Tweakable Key-Alternating Feistel Block Cipher [PDF]

Symmetry, 2021
This paper focuses on designing a tweakable block cipher via by tweaking the Key-Alternating Feistel (KAF for short) construction. Very recently Yan et al. published a tweakable KAF construction. It provides a birthday-bound security with 4 rounds and Beyond-Birthday-Bound (BBB for short) security with 10 rounds. Following their work, we further reduce

Boomerang Connectivity Table:A New Cryptanalysis Tool [PDF]

, 2018
A boomerang attack is a cryptanalysis framework that regards a block cipher $E$ as the composition of two sub-ciphers $E_1\circ E_0$ and builds a particular characteristic for $E$ with probability $p^2q^2$ by combining differential characteristics for ...

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.

Triplex: an Efficient and One-Pass Leakage-Resistant Mode of Operation

Transactions on Cryptographic Hardware and Embedded Systems, 2022
This paper introduces and analyzes Triplex, a leakage-resistant mode of operation based on Tweakable Block Ciphers (TBCs) with 2n-bit tweaks. Triplex enjoys beyond-birthday ciphertext integrity in the presence of encryption and decryption leakage in a ...
