Integral Cryptanalysis Using Algebraic Transition Matrices by Tim Beyne, Michiel Verbauwhede

“… In this work we introduce algebraic transition matrices as the basis for a new approach to integral cryptanalysis that unifies monomial trails (Hu et al., Asiacrypt 2020) and parity sets (Boura and Canteaut, Crypto 2016). …”

Cryptanalysis of Efficient Masked Ciphers: Applications to Low Latency by Tim Beyne, Siemen Dhooghe, Amir Moradi, Aein Rezaei Shahmirzadi

“…The main idea lies on a combination of the constructions given by Shahmirzadi and Moradi at CHES 2021, and the theory presented by Beyne et al. at Asiacrypt 2020. The presented masked designs only use a minimal number of shares, i.e., three to achieve second-order security, and we make use of a trick to pair a couple of S-boxes to reduce their latency. …”
