How to Govern the Confidence Machine?

Regulation &Governance, Volume 19, Issue 3, Page 706-721, July 2025.
ABSTRACT Emerging technologies pose many new challenges for regulation and governance on a global scale. With the advent of distributed communication networks like the Internet and decentralized ledger technologies like blockchain, new platforms emerged, disrupting existing power dynamics and bringing about new claims of sovereignty from the private ...

THE TABULAR OF CRYPTOGRAPHIC PRIMITIVES OF NONLINEAR SUBSTITUTIONS

Ìнформаційні технології в освіті, 2015
Classic primitives nonlinear substitution is a simple replacing each character encrypted text on a fixed symbol of the same alphabet, actually realizing the transformation one alphabet simple substitution cipher. And as a consequence - the entropy cipher

Block encryption of quantum messages [PDF]

, 2018
In modern cryptography, block encryption is a fundamental cryptographic primitive. However, it is impossible for block encryption to achieve the same security as one-time pad.

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

A Novel Identity-Based Signcryption Scheme in the Standard Model

Information, 2017
Identity-based signcryption is a useful cryptographic primitive that provides both authentication and confidentiality for identity-based crypto systems. It is challenging to build a secure identity-based signcryption scheme that can be proven secure in a

Physically Unclonable Function Utilizing Stochastic Indirect Exchange Interaction

Small Structures, Volume 6, Issue 6, June 2025.
A physically unclonable function (PUF) utilizes manufacturing variations to create secret keys. This study proposes a spin–orbit torque PUF model based on the Ruderman–Kittel–Kasuya–Yosida interaction. It features near‐ideal properties that can operate under zero magnetic field and varying temperatures.

On Quasi‐Hermitian Varieties in Even Characteristic and Related Orthogonal Arrays

Journal of Combinatorial Designs, Volume 33, Issue 3, Page 109-122, March 2025.
ABSTRACT In this article, we study the BM quasi‐Hermitian varieties, laying in the three‐dimensional Desarguesian projective space of even order. After a brief investigation of their combinatorial properties, we first show that all of these varieties are projectively equivalent, exhibiting a behavior which is strikingly different from what happens in ...

Certifying RSA public keys with an efficient NIZK [PDF]

, 2018
In many applications, it is important to verify that an RSA public key ( N,e ) specifies a permutation, in order to prevent attacks due to adversarially-generated public keys.

Secure two-party quantum evaluation of unitaries against specious adversaries

, 2010
We describe how any two-party quantum computation, specified by a unitary which simultaneously acts on the registers of both parties, can be privately implemented against a quantum version of classical semi-honest adversaries that we call specious.
