Realization Scheme for Visual Cryptography with Computer-generated Holograms [PDF]
arXiv, 2022 We propose to realize visual cryptography in an indirect way with the help of computer-generated hologram. At present, the recovery method of visual cryptography is mainly superimposed on transparent film or superimposed by computer equipment, which greatly limits the application range of visual cryptography.

Quantum-Resistant Cryptography [PDF]
arXiv, 2021 Quantum-resistant cryptography is cryptography that aims to deliver cryptographic functions and protocols that remain secure even if large-scale fault-tolerant quantum computers are built. NIST will soon announce the first selected public-key cryptography algorithms in its Post-Quantum Cryptography (PQC) standardization which is the most important ...

ECDSA White-Box Implementations: Attacks and Designs from CHES 2021 Challenge
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Despite the growing demand for software implementations of ECDSA secure against attackers with full control of the execution environment, scientific literature on ECDSA white-box design is scarce. The CHES 2021 WhibOx contest was thus held to assess the

Characterisations of Ideal Threshold Schemes [PDF]
Discrete Mathematics & Theoretical Computer Science, 2004 We characterise ideal threshold schemes from different approaches. Since the characteristic properties are independent to particular descriptions of threshold schemes all ideal threshold schemes can be examined by new points of view and new results on ...

Boosting Differential-Linear Cryptanalysis of ChaCha7 with MILP
IACR Transactions on Symmetric Cryptology, 2023 In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new differential-linear distinguishers that we were able to build thanks to the following improvements: a) we considered a ...
