Some Algebraic Properties of RX-Differential Probabilities of Boolean Mappings
Кібернетика та комп'ютерні технологіїIntroduction. ARX- and LRX- cryptosystems are based on extremely simple operations available at the level of computing processor instructions, such as modular addition, bitwise addition, rotations, etc.

Towards a combined Rotational-Differential Cryptanalytic Framework [PDF]
, 2014 In this report, we suggest a new cryptanalytic framework of constructing distinguishers which can be eventually extended to full attacks in the related-key scenario. We name this new paradigm as ”Relational Cryptanalysis”. The main idea is to exhibit the

Synesthesia: Detecting Screen Content via Remote Acoustic Side Channels
, 2019 We show that subtle acoustic noises emanating from within computer screens can be used to detect the content displayed on the screens. This sound can be picked up by ordinary microphones built into webcams or screens, and is inadvertently transmitted to ...

Differential Cryptanalysis with SAT, SMT, MILP, and CP: A Detailed Comparison for Bit-Oriented Primitives [PDF]
, 2023 SAT, SMT, MILP, and CP, have become prominent in the differential cryptanalysis of cryptographic primitives. In this paper, we review the techniques for constructing differential characteristic search models in these four formalisms.
