Improved Conditional Differential Analysis on NLFSR Based Block Cipher KATAN32 with MILP [PDF]
Wireless Communications and Mobile Computing, 2020 In this paper, a new method for constructing a Mixed Integer Linear Programming (MILP) model on conditional differential cryptanalysis of the nonlinear feedback shift register- (NLFSR-) based block ciphers is proposed, and an approach to detecting the bit with a strongly biased difference is provided.

Security Analysis of the GF-NLFSR Structure and Four-Cell Block Cipher [PDF]
, 2009 The overall structure is one of the most important properties of block ciphers. At present, the most common structures include Feistel structure, SP structure, MISTY structure, L-M structure and Generalized Feistel structure. In [12], Choy et al. proposed a new structure called GF-NLFSR (Generalized Feistel-NonLinear Feedback Shift Register), and ...

New Family of Stream Ciphers as Physically Clone-Resistant VLSI-Structures
Cryptography, 2019 A concept for creating a large class of lightweight stream ciphers as Key Stream Generators KSGs is presented. The resulting class-size exceeds 2323 possible different KSGs.

IET Computers &Digital Techniques, Volume 17, Issue 3-4, Page 75-88, May-July 2023., 2023 A comprehensive evaluation of the seven (out of 10) algorithm finalists of the NIST IoT lightweight cipher competition that do not integrate built‐in countermeasures is proposed. The study shows that, nonetheless, they still present some residual vulnerabilities to power SCA.

Conditional differential analysis on the KATAN ciphers based on deep learning
IET Information Security, Volume 17, Issue 3, Page 347-359, May 2023., 2023 KATAN ciphers are block ciphers using non‐linear feedback shift registers. In this study, the authors improve the results of conditional differential analysis on KATAN by using deep learning. We present a practical key recovery attack on the 97‐round KATAN32 with 215.5 data complexity and 220.5 time complexity. The attack of the 82‐round KATAN48 and 70‐

Improved Impossible Differentials and Zero‐Correlation Linear Hulls of New Structure III
Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021 Impossible differential cryptanalysis and zero‐correlation linear cryptanalysis are two kinds of most effective tools for evaluating the security of block ciphers. In those attacks, the core step is to construct a distinguisher as long as possible. In this paper, we focus on the security of New Structure III, which is a kind of block cipher structure ...

On the Security Margin of TinyJAMBU with Refined Differential and Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology, 2020 This paper presents the first third-party security analysis of TinyJAMBU, which is one of 32 second-round candidates in NIST’s lightweight cryptography standardization process. TinyJAMBU adopts an NLFSR based keyed-permutation that computes only a single
