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 Conditional Differential Analysis on NLFSR‐Based Block Cipher KATAN32 with MILP
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.

Randomness Generation for Secure Hardware Masking - Unrolled Trivium to the Rescue [PDF]
, 2023 Masking is a prominent strategy to protect cryptographic implementations against side-channel analysis. Its popularity arises from the exponential security gains that can be achieved for (approximately) quadratic resource utilization.

Fast Near Collision Attack on the Grain v1 Stream Cipher [PDF]
, 2018 Modern stream ciphers often adopt a large internal state to resist various attacks, where the cryptanalysts have to deal with a large number of variables when mounting state recovery attacks.

Near Collision Attack Against Grain v1 [PDF]
, 2023 A near collision attack against the Grain v1 stream cipher was proposed by Zhang et al. in Eurocrypt 18. The attack uses the fact that two internal states of the stream cipher with very low hamming distance between them, produce similar keystream ...
