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. We show that the related-tweakey differential bounds provided by the designers can be greatly improved thanks to a Mixed ...

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 ...

A Tweakable Enciphering Mode [PDF]
, 2003 We describe a block-cipher mode of operation, CMC, that turns an n-bit block cipher into a tweakable enciphering scheme that acts on strings of mn bits, where m>=2.

Comprehensive security analysis of CRAFT
IACR Transactions on Symmetric Cryptology, 2020 CRAFT is a lightweight block cipher, designed to provide efficient protection against differential fault attacks. It is a tweakable cipher that includes 32 rounds to produce a ciphertext from a 64-bit plaintext using a 128-bit key and 64-bit public tweak.

Key Committing Security of AEZ and More
IACR Transactions on Symmetric Cryptology, 2023 For an Authenticated Encryption with Associated Data (AEAD) scheme, the key committing security refers to the security notion of whether the adversary can produce a pair of distinct input tuples, including the key, that result in the same output.

Building PRFs from TPRPs: Beyond the Block and the Tweak Length Bounds
IACR Transactions on Symmetric CryptologyA secure n-bit tweakable block cipher (TBC) using t-bit tweaks can be modeled as a tweakable uniform random permutation, where each tweak defines an independent random n-bit permutation.

IACR Transactions on Symmetric Cryptology, 2017 CAESAR has caused a heated discussion regarding the merits of one-pass encryption and online ciphers. The latter is a keyed, length preserving function which outputs ciphertext blocks as soon as the respective plaintext block is available as input.

Key‐dependent side‐channel cube attack on CRAFT
ETRI Journal, 2021 CRAFT is a tweakable block cipher introduced in 2019 that aims to provide strong protection against differential fault analysis. In this paper, we show that CRAFT is vulnerable to side‐channel cube attacks.

Business Strategy and the Environment, EarlyView.ABSTRACT This scoping review provides an industry‐comparative synthesis of greenwashing and disclosure‐action decoupling in sustainability‐related reporting. Guided by PRISMA, it reviews 73 peer‐reviewed articles published between 2016 and 2025 and organizes them into three streams: variable‐based explanatory, report analysis, and disclosure‐action ...
