General Classification of the Authenticated Encryption Schemes for the CAESAR Competition [PDF]
, 2016 An Authenticated encryption scheme is a scheme which provides privacy and integrity by using a secret key. In 2013, CAESAR (the ``Competition for Authenticated Encryption: Security, Applicability, and Robustness\u27\u27) was co-founded by NIST and Dan ...

Parallel SAT Framework to Find Clustering of Differential Characteristics and Its Applications [PDF]
, 2023 The most crucial but time-consuming task for differential cryptanalysis is to find a differential with a high probability. To tackle this task, we propose a new SAT-based automatic search framework to efficiently figure out a differential with the ...

Impossible Boomerang Attacks Revisited: Applications to Deoxys-BC, Joltik-BC and SKINNY [PDF]
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.

Efficient Beyond-Birthday-Bound-Secure Deterministic Authenticated Encryption with Minimal Stretch [PDF]
, 2016 Block-cipher-based authenticated encryption has obtained considerable attention from the ongoing CAESAR competition. While the focus of CAESAR resides primarily on nonce-based authenticated encryption, Deterministic Authenticated Encryption (DAE) is used

A Note on the use of the Double Boomerang Connectivity Table (DBCT) for Spotting Impossibilities [PDF]
In this short note we examine one of the impossible boomerang distinguishers of Skinny-128-384 provided by Zhang, Wang and Tang at ToSC 2024 Issue 2 and disprove it.

New Records for Practical-data Chosen-plaintext Attacks on Round-reduced AES [PDF]
As probably the most widespread block cipher, the AES has attracted tremendous cryptanalytical efforts since its standardization. In the single secret-key setting, Demirci-Selcuk Meet-in-the-Middle (DS-MitM) attacks have remained the state of the art on ...

MILP-aided Cube-attack-like Cryptanalysis on Keccak Keyed Modes [PDF]
, 2018 Cube-attack-like cryptanalysis was proposed by Dinur et al. at EUROCRYPT 2015, which recovers the key of Keccak keyed modes in a divide-and-conquer manner. In their attack, one selects cube variables manually, which leads to more key bits involved in the
