Multiple Impossible Differential Attacks for ForkAES

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
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

IET Information Security, Volume 15, Issue 3, Page 247-255, May 2021., 2021
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

IACR Transactions on Symmetric Cryptology, 2018
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

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 ...

A Security Analysis of Deoxys and its Internal Tweakable Block Ciphers

IACR Transactions on Symmetric Cryptology, 2017
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

IACR Transactions on Symmetric Cryptology, 2017
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.

Analysis of AES, SKINNY, and Others with Constraint Programming

IACR Transactions on Symmetric Cryptology, 2017
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.

Differential Cryptanalysis on Block Cipher Skinny with MILP Program

Security and Communication Networks, Volume 2018, Issue 1, 2018., 2018
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.

Impossible Boomerang Attacks Revisited

IACR Transactions on Symmetric Cryptology
The impossible boomerang (IB) attack was first introduced by Lu in his doctoral thesis and subsequently published at DCC in 2011. The IB attack is a variant of the impossible differential (ID) attack by incorporating the idea of the boomerang attack. In

A Note on Related-Tweakey Impossible Differential Attacks

IACR Communications in Cryptology
In this note we review the technique proposed at ToSC 2018 by Sadeghi et al. for attacks built upon several related-tweakey impossible differential trails. We show that the initial encryption queries are improper and lead the authors to misevaluate a filtering value in the key recovery phase.
