Full PRF-Secure Message Authentication Code Based on Tweakable Block Cipher
Provable Security, 2015We propose a new message authentication code MAC based on a tweakable block cipher TBC. We prove that the new MAC is a pseudo-random function PRF upi¾?to $$O2^n$$ queries, that is, full PRF-security, where the output length of the TBC is n bits. We note that although Yasuda proposed a full PRF-secure MAC based on a compression function CF, that does ...

Tweakable Block Mode of Operation for Disk Encompression Using Cipher Text Stealing
, 2020In this paper, we study a particular class of symmetric algorithms that aim to ensure confidentiality by using a functionality that is tweakable enciphering scheme. A tweakable enciphering scheme is a length preserving encryption protocol which can encrypt messages of varying lengths.

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.

The MALICIOUS Framework: Embedding Backdoors into Tweakable Block Ciphers
2020Inserting backdoors in encryption algorithms has long seemed like a very interesting, yet difficult problem. Most attempts have been unsuccessful for symmetric-key primitives so far and it remains an open problem how to build such ciphers.

Post-Quantum Security of Block Cipher Constructions
arXiv.orgBlock ciphers are versatile cryptographic ingredients that are used in a wide range of applications ranging from secure Internet communications to disk encryption. While post-quantum security of public-key cryptography has received significant attention,

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.
