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.

HCTR+: An Optimally Secure TBC-Based Accordion Mode

IACR Transactions on Symmetric Cryptology
The design of tweakable wide-block ciphers has advanced significantly over the past two decades. This evolution began with the wide-block cipher by Naor and Reingold.

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 ...

Local Search and the Evolution of World Models

Topics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

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.

MMM: Authenticated Encryption with Minimum Secret State for Masking

Transactions on Cryptographic Hardware and Embedded Systems, 2023
We propose a new authenticated encryption (AE) mode MMM that achieves the minimum memory size with masking. Minimizing the secret state is the crucial challenge in the low-memory AE suitable for masking.

Spook: Sponge-Based Leakage-Resistant Authenticated Encryption with a Masked Tweakable Block Cipher

IACR Transactions on Symmetric Cryptology, 2020
This paper defines Spook: a sponge-based authenticated encryption with associated data algorithm. It is primarily designed to provide security against side-channel attacks at a low energy cost. For this purpose, Spook is mixing a leakageresistant mode of
