Analysis of an Optimal Fault Attack on the LED-64 Lightweight Cryptosystem

open access: yesIEEE Access, 2019
This paper presents an optimal method for recovering the secret keys of the light encryption device (LED) by combining the impossible differential fault attack with the algebraic differential fault attack. The proposed optimal method effectively improves

New attacks against reduced Rijndael‐160

open access: yesIET Information Security, 2022
The first 9‐round meet‐in‐the‐middle (MITM) attack and improved 8‐round impossible differential (ID) attacks on Rijndael‐160 are studied here. For the first 9‐round MITM attack, a new effective attack path is explored by using the generalised δ‐set and ...

Cryptanalysis of Reduced round SKINNY Block Cipher

open access: yesIACR Transactions on Symmetric Cryptology, 2018
SKINNY is a family of lightweight tweakable block ciphers designed to have the smallest hardware footprint. In this paper, we present zero-correlation linear approximations and the related-tweakey impossible differential characteristics for different ...

MILP-Aided Related-Tweak/Key Impossible Differential Attack and its Applications to QARMA, Joltik-BC

open access: yesIEEE Access, 2019
In this paper, we study the relation of related-tweak/key impossible differentials with single-key ones. Following a heuristic strategy, we can derive longer related-tweak/key impossible differentials from single-key ones. We implement this strategy with

An Improved Impossible Differential Attack on MISTY1 [PDF]

open access: yes, 2008
MISTY1 is a Feistel block cipher that received a great deal of cryptographic attention. Its recursive structure, as well as the added FL layers, have been successful in thwarting various cryptanalytic techniques. The best known attacks on reduced variants of the cipher are on either a 4-round variant with the FL functions, or a 6-round variant without ...

Cryptanalysis of NBC-128

open access: yesDianzi Jishu Yingyong, 2021
NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.

On the Usage of Deterministic (Related-Key) Truncated Differentials and Multidimensional Linear Approximations for SPN Ciphers

open access: yesIACR Transactions on Symmetric Cryptology, 2020
Among the few works realising the search of truncated differentials (TD) and multidimensional linear approximations (MDLA) holding for sure, the optimality of the distinguisher should be confirmed via an exhaustive search over all possible input ...
