Improved Conditional Differential Analysis on NLFSR‐Based Block Cipher KATAN32 with MILP [PDF]
Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 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.

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 ...

Impossible Differential Distinguishers of Two Generalized Feistel Structures
Security and Communication Networks, Volume 2020, Issue 1, 2020., 2020 Generalized Feistel structures are widely used in the design of block ciphers. In this paper, we focused on retrieving impossible differentials for two kinds of generalized Feistel structures: CAST256‐like structure with Substitution‐Permutation (SP) or Substitution‐Permutation‐Substitution (SPS) round functions (named CAST256SP and CAST256SPS ...

Stream ciphers: A Practical Solution for Efficient Homomorphic-Ciphertext Compression [PDF]
, 2015 International audienceIn typical applications of homomorphic encryption, the first step consists for Alice to encrypt some plaintext m under Bob’s public key pk and to send the ciphertext c = HEpk(m) to some third-party evaluator Charlie.
