Improved Rectangle Attacks on SKINNY and CRAFT

IACR Transactions on Symmetric Cryptology, 2021
The boomerang and rectangle attacks are adaptions of differential cryptanalysis that regard the target cipher E as a composition of two sub-ciphers, i.e., E = E1 ∘ E0, to construct a distinguisher for E with probability p2q2 by concatenating two short ...

Compact Hardware Implementations of ChaCha, BLAKE, Threefish, and Skein on FPGA [PDF]

, 2014
The cryptographic hash functions BLAKE and Skein are built from the ChaCha stream cipher and the tweakable Threefish block cipher, respectively. Interestingly enough, they are based on the same arithmetic operations, and the same design philosophy allows

Improved Meet-in-the-Middle Preimage Attacks against AES Hashing Modes

IACR Transactions on Symmetric Cryptology, 2020
Hashing modes are ways to convert a block cipher into a hash function, and those with AES as the underlying block cipher are referred to as AES hashing modes.

Tweakable HCTR: A BBB Secure Tweakable Enciphering Scheme [PDF]

, 2019
\textsf{HCTR}, proposed by Wang et al., is one of the most efficient candidates of tweakable enciphering schemes that turns an $n$-bit block cipher into a variable input length tweakable block cipher. Wang et al.

Linear Cryptanalysis: Key Schedules and Tweakable Block Ciphers

IACR Transactions on Symmetric Cryptology, 2017
This paper serves as a systematization of knowledge of linear cryptanalysis and provides novel insights in the areas of key schedule design and tweakable block ciphers. We examine in a step by step manner the linear hull theorem in a general and consistent setting.

Clustering Related-Tweak Characteristics: Application to MANTIS-6

IACR Transactions on Symmetric Cryptology, 2018
The TWEAKEY/STK construction is an increasingly popular approach for designing tweakable block ciphers that notably uses a linear tweakey schedule. Several recent attacks have analyzed the implications of this approach for differential cryptanalysis and ...
