Tweakable Block Mode of Operation for Disk Encompression Using Cipher Text Stealing

2021
In 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.

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

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

ZMAC: A Fast Tweakable Block Cipher Mode for Highly Secure Message Authentication

2017
We propose a new mode of operation called \(\mathsf {ZMAC}\) allowing to construct a (stateless and deterministic) message authentication code (MAC) from a tweakable block cipher (TBC). When using a TBC with n-bit blocks and t-bit tweaks, our construction provides security (as a variable-input-length PRF) beyond the birthday bound with respect to the ...

Full PRF-Secure Message Authentication Code Based on Tweakable Block Cipher

2015
We 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 ...
