Sensors, 2023 The access control (AC) system in an IoT (Internet of Things) context ensures that only authorized entities have access to specific devices and that the authorization procedure is based on pre-established rules. Recently, blockchain-based AC systems have

Cybersecurity, 2018 Concurrent non-malleable zero-knowledge (CNMZK) considers the concurrent execution of zero-knowledge protocols in a setting even when adversaries can simultaneously corrupt multiple provers and verifiers.

Authentication algorithm for internet of things networks based on MQTT protocol [PDF]
Serbian Journal of Electrical Engineering, 2020 The authentication algorithm for machine-to-machine communication devices via the MQTT Protocol is considered, which allows verifying the device legality without sending the password.

A Lattice-Based Certificateless Traceable Ring Signature Scheme
Information, 2023 A ring signature (RS) scheme enables a group member to sign messages on behalf of its group without revealing the definite signer identify, but this also leads to the abuse of anonymity by malicious signers, which can be prevented by traceable ring ...

Designing a Practical Code-Based Signature Scheme from Zero-Knowledge Proofs with Trusted Setup
Cryptography, 2022 This paper defines a new practical construction for a code-based signature scheme. We introduce a new protocol that is designed to follow the recent paradigm known as “Sigma protocol with helper”, and prove that the protocol’s security reduces directly ...

Proceedings of the 2021 7th Student Computer Science Research Conference (StuCoSReC), 2021 Zero-Knowledge proofs (ZKPs) enable proving of mathematical statements, revealing nothing but their validity. We design an authentication sys-tem with a ZKP as a password verification mech-anism within the Extensible Authentication Pro-tocol (EAP) framework.

Classical zero-knowledge arguments for quantum computations [PDF]
Quantum, 2020 We show that every language in QMA admits a classical-verifier, quantum-prover zero-knowledge argument system which is sound against quantum polynomial-time provers and zero-knowledge for classical (and quantum) polynomial-time verifiers.

ZPiE: Zero-Knowledge Proofs in Embedded Systems
Mathematics, 2021 Zero-Knowledge Proofs (ZKPs) are cryptographic primitives allowing a party to prove to another party that the former knows some information while keeping it secret.

Circuitree: A Datalog Reasoner in Zero-Knowledge
IEEE Access, 2022 Driven by the increased consciousness in data ownership and privacy, zero-knowledge proofs (ZKPs) have become a popular tool to convince a third party of the truthfulness of a statement without disclosing any further information.

Improving the Performance of the Picnic Signature Scheme
Transactions on Cryptographic Hardware and Embedded Systems, 2020 Picnic is a digital signature algorithm designed to provide security against attacks by quantum computers. The design uses only symmetric-key primitives, and is an efficient instantiation of the MPC-in-the-head paradigm.
