Dialga: A Family of Low-Latency Tweakable Block Ciphers Using Multiple Linear Layers
IACR Transactions on Symmetric CryptologyIn this paper, we propose Dialga, a family of low-latency tweakable block ciphers designed to support 128/256-bit tweaks and 256-bit keys. Dialga achieves significantly small latency by leveraging multiple novel strategies.

Computing the Differential Probability of a Word-Based Block Cipher
CryptographyDifferential cryptanalysis is one of the fundamental cryptanalysis techniques to evaluate the security of the block cipher. In many cases, resistance to differential cryptanalysis is proven through the upper bound of the differential characteristic ...

Key Guessing Strategies for Linear Key-Schedule Algorithms in Rectangle Attacks [PDF]
, 2022 When generating quartets for the rectangle attacks on ciphers with linear key-schedule, we find the right quartets which may suggest key candidates have to satisfy some nonlinear relations. However, some quartets generated always violate these relations,

How to Use Metaheuristics for Design of Symmetric-Key Primitives [PDF]
, 2017 The ultimate goal of designing a symmetric-key cryptographic primitive often can be formulated as an optimization problem. So far, these problems mainly have been solved with trivial algorithms such as brute force or random search.

Finding the Impossible: Automated Search for Full Impossible-Differential, Zero-Correlation, and Integral Attacks [PDF]
, 2023 Impossible differential (ID), zero-correlation (ZC), and integral attacks are a family of important attacks on block ciphers. For example, the impossible differential attack was the first cryptanalytic attack on 7 rounds of AES.

Pholkos -- Efficient Large-state Tweakable Block Ciphers from the AES Round Function [PDF]
, 2020 With the dawn of quantum computers, higher security than $128$ bits has become desirable for primitives and modes. During the past decade, highly secure hash functions, MACs, and encryption schemes have been built primarily on top of keyless permutations,
