Improved Rectangle Attacks on SKINNY and CRAFT
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 ...

Efficient constructions for large‐state block ciphers based on AES New Instructions
Abstract Large‐state block ciphers with 256 bits or 512 bits block sizes receive much attention from the viewpoint of long‐term security. Existing large‐state block ciphers, such as Haraka‐v2 and Pholkos, consist of only the AES New Instructions set (AES‐NI) and a word shuffle that can be efficiently executed by SIMD instructions for fast software ...

Multiple Impossible Differential Attacks for ForkAES
To yield a highly efficient authentication encryption design for very short messages, the tweakable forkcipher is proposed, which is a tweakable block cipher that uses forking construction to produce two output blocks. The designers also presented ForkAES, a forkcipher that is based on the round function of AES and the tweakable variant of KIASU ...

Improved meet‐in‐the‐middle attacks on reduced‐round Joltik‐BC
Abstract Joltik‐BC is an internal tweakable block cipher of the authenticated encryption algorithm Joltik, which was a second‐round finalist in the CAESAR competition. The authors study the key‐recovery attacks on Joltik‐BC under meet‐in‐the‐middle attack.

Cryptanalysis of Reduced round SKINNY Block Cipher
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different ...

Clustering Related-Tweak Characteristics: Application to MANTIS-6
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 ...

A Security Analysis of Deoxys and its Internal Tweakable Block Ciphers
In this article, we provide the first independent security analysis of Deoxys, a third-round authenticated encryption candidate of the CAESAR competition, and its internal tweakable block ciphers Deoxys-BC-256 and Deoxys-BC-384.

Practical Key-Recovery Attack on MANTIS5
MANTIS is a lightweight tweakable block cipher published at CRYPTO 2016. In addition to the full 14-round version, MANTIS7, the designers also propose an aggressive 10-round version, MANTIS5.

Differential Cryptanalysis on Block Cipher Skinny with MILP Program
With the widespread use of RFID technology and the rapid development of Internet of Things, the research of lightweight block cipher has become one of the hot issues in cryptography research. In recent years, lightweight block ciphers have emerged and are widely used, and their security is also crucial.

Analysis of AES, SKINNY, and Others with Constraint Programming
Search for different types of distinguishers are common tasks in symmetrickey cryptanalysis. In this work, we employ the constraint programming (CP) technique to tackle such problems.
