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 ...

Related-Key Differential Cryptanalysis of the Reduced-Round Block Cipher GIFT
IEEE Access, 2019 GIFT is a lightweight block cipher that was proposed by Banik et al. at CHES 2017, which is said to be a direct improvement over PRESENT since “that provides a much increased efficiency in all domains (smaller and faster)” and improves the ...

MILP-Based Differential Cryptanalysis on Round-Reduced Midori64
IEEE Access, 2020 Mixed integer linear programming (MILP) model was presented by Sun et al. at Asiacrypt 2014 to search for differential characteristics of block ciphers. Based on this model, it is easy to assess block ciphers against differential attack.

Differential Cryptanalysis of Round-Reduced SPECK Suitable for Internet of Things Devices [PDF]
IEEE Access, 2019 In this paper, we focus on differential cryptanalysis of a lightweight ARX cipher. These ciphers use three simple arithmetic operations, namely, modular addition, bitwise rotation, and exclusive-OR, and therefore, are designed very well to perform over ...

Improving Differential-Neural Cryptanalysis
IACR Communications in CryptologyOur first objective is to enhance the capabilities of differential-neural distinguishers by applying more deep-learning techniques, focusing on handling more rounds and improving accuracy. Inspired by the Inception Block in GoogLeNet, we adopted a design that uses multiple parallel convolutional layers with varying kernel sizes before the residual

Improved Differential Cryptanalysis of SPEEDY
IACR Transactions on Symmetric CryptologySPEEDY is a family of lightweight block ciphers designed by Leander et al. Several differential attacks have been reported on the SPEEDY variants. However, nearly all of these attacks are based on differential characteristics with probabilities that ...
