Related-Key Differential Attacks on COSB-128
International Journal of Distributed Sensor Networks, 2015 COSB-128 (Moldovyan et al., 2002) is a block cipher with 128-bit and 256-bit secret keys, which use key and data-dependent operational substitutions in fast controllable permutation blocks (CPB) concept.

Differential Cryptanalysis of KHF [PDF]
, 1998 Bakhtiari et al recently proposed a fast message authentication primitive called KHF. This paper shows that KHF is highly vulnerable to differential cryptanalysis: it can be broken with about 37 chosen message queries. This suggests that the KHF design should be reconsidered.

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications
Advanced Intelligent Systems, EarlyView.To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...

Links between differential and linear cryptanalysis
, 2006 Linear cryptanalysis, introduced in 1994 by Matsui, will most certainly open-up the way to new attack methods which may be made more efficient when compared or combined with differential cryptanalysis. This paper exhibits new relations between linear and

Differential Cryptanalysis of Round-Reduced LEA
IEEE Access, 2018 In this paper, we focus on the differential cryptanalysis dedicated to a particular class of cryptographic algorithms, namely ARX ciphers. We propose a new algorithm inspired by the Nested Monte-Carlo Search algorithm to find a differential path in ARX ...

Dianzi 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.

Differential Cryptanalysis of Nimbus [PDF]
, 2002 Nimbus is a block cipher submitted as a candidate to the NESSIE project by Alexis Machado. Like many other ciphers Nimbus combines multiplication operations with XOR operations, a common technique to protect against various kinds of cryptanalysis.In this paper we present two new differential properties of multiplication operations with probability ...

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences
Mathematische Nachrichten, EarlyView.ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.
