An Access Control System Based on Blockchain with Zero-Knowledge Rollups in High-Traffic IoT Environments [PDF]
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

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 ...

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 ...

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.

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.
