Tweakable block ciphers are important primitives for designing cryptographic schemes with high security. In the absence of a standardized tweakable block cipher, constructions built from classical block ciphers remain an interesting research topic in both theory and practice. Motivated by Mennink’s \(\widetilde{F}[2]\) publication from 2015, Wang et al.

Elastic-Tweak: A Framework for Short Tweak Tweakable Block Cipher
2021Tweakable block cipher (TBC), a stronger notion than standard block ciphers, has wide-scale applications in symmetric-key schemes. At a high level, it provides flexibility in design and (possibly) better security bounds. In multi-keyed applications, a TBC with short tweak values can be used to replace multiple keys.

Arguments for Tweakable Block Cipher-Based Cryptography
2021As discussed in Sect. 1.3, a TBC is a variant of a BC that accepts a public tweak to change its behavior. TBC-based AEAD designs have a lot of nice performance and security features that we will discuss in this chapter. First, we give an early history of TBC designs in Sect. 4.1. Then, we discuss the impact of the TWEAKEY framework in Sect. 4.2.

Romulus: Lighweight AEAD from Tweakable Block Ciphers
2021In this chapter, we present the NIST lightweight finalist, Romulus. It is a family of lightweight, very efficient, and highly-secure algorithms; including, but not restricted to, NAE (Romulus-N) and MRAE (Romulus-M) schemes.

Compactly Committing Authenticated Encryption Using Tweakable Block Cipher
2020Message franking is a cryptographic scheme introduced in the Facebook end-to-end encrypted messaging system. It enables users to report abusive messages to Facebook in a verifiable manner. Grubbs, Lu and Ristenpart initiated theoretical study of message franking.

Length-Preserving Encryption Based on Single-Key Tweakable Block Cipher
2018We present a Single-key Length Doubler built on an n-bit Tweakable block cipher (SLDT), which is a length-preserving cipher on the strings with bit length in integer interval \(\left[ n, n+1, \ldots , 2n-1\right] \). SLDT is mainly motivated to reduce the key material size of a length doubler proposed by Chen et al. at FSE2018, since the key management
