On the concept of quantum hashing
Математические вопросы криптографии, 2016 Понятие квантового хеширования вводится как естественное обобщение классического хеширования. Предлагаются определение квантового хеширующего генератора и способ построения большого числа различных квантовых хеширующих функций. Построение основано на композиции классического $\varepsilon$-универсального семейства и заданного семейства функций ...

Side-Channel Protections for Picnic Signatures
Transactions on Cryptographic Hardware and Embedded Systems, 2021 We study masking countermeasures for side-channel attacks against signature schemes constructed from the MPC-in-the-head paradigm, specifically when the MPC protocol uses preprocessing.

Quantum Communications Based on Quantum Hashing
CoRR, 2013 In this paper we consider an application of the recently proposed quantum hashing technique for computing Boolean functions in the quantum communication model. The combination of binary functions on non-binary quantum hash function is done via polynomial presentation, which we have called a characteristic of a Boolean function.

Fully-Parallel Quantum Turbo Decoder
IEEE Access, 2016 Quantum turbo codes (QTCs) are known to operate close to the achievable Hashing bound. However, the sequential nature of the conventional quantum turbo decoding algorithm imposes a high decoding latency, which increases linearly with the frame length ...

Quantum Hashing via Classical $ε$-universal Hashing Constructions
CoRR, 2014 In the paper, we define the concept of the quantum hash generator and offer design, which allows to build a large amount of different quantum hash functions. The construction is based on composition of classical $ε$-universal hash family and a given family of functions -- quantum hash generator.

SiOx‐Based Probabilistic Bits Enabling Invertible Logic Gate for Cryptographic Applications
Advanced Intelligent Systems, EarlyView.To enable lightweight hardware encryption and decryption, a Ti/SiOx/Ti threshold switching device is engineered to generate controllable stochastic oscillations. By tuning the input voltage, the device produces a programmable spike probability governed by intrinsic switching dynamics, enabling probabilistic bits that construct an invertible ...
