Length-Preserving Encryption Based on Single-Key Tweakable Block Cipher

Lecture Notes in Computer Science, 2018
We 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

Almost-Minimal-Round BBB-Secure Tweakable Key-Alternating Feistel Block Cipher

Symmetry, 2021
This paper focuses on designing a tweakable block cipher via by tweaking the Key-Alternating Feistel (KAF for short) construction. Very recently Yan et al. published a tweakable KAF construction.

MATTER: A Wide-Block Tweakable Block Cipher. [PDF]

IACR Cryptol. ePrint Arch.
In this note, we introduce the MATTER Tweakable Block Cipher, designed principally for low latency in low-area hardware implementations, but that can also be implemented in an efficient and compact way in software.

WCFB: a tweakable wide block cipher. [PDF]

IACR Cryptol. ePrint Arch., 2014
We define a model for applications that process large data sets in a way that enables additional optimizations of encryption operations. We designed a new strong pseudo-random tweakable permutation, WCFB, to take advantage of identified characteristics ...

Arguments for Tweakable Block Cipher-Based Cryptography

2021
As 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

2021
In 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.
