Representative Ring Signature Algorithm Based on Smart Contract [PDF]

Sensors, 2022
Traditional ring signature algorithms suffer from large signature data capacity and low speed of signature and verification during collective signing. In this work, we propose a representative ring signature algorithm based on smart contracts.

A Novel Linkable Ring Signature on Ideal Lattices [PDF]

Entropy, 2023
In this paper, a novel linkable ring signature scheme is constructed. The hash value of the public key in the ring and the signer’s private key are based on random numbers.

A Survey on Group Signatures and Ring Signatures: Traceability vs. Anonymity [PDF]

Cryptography, 2022
This survey reviews the two most prominent group-oriented anonymous signature schemes and analyzes the existing approaches for their problem: balancing anonymity against traceability.

Logarithmic-Size Post-Quantum Linkable Ring Signatures Based on Aggregation Operations [PDF]

Entropy
Linkable ring signatures are a type of ring signature scheme that can protect the anonymity of signers while allowing the public to verify whether the same signer has signed the same message multiple times.

ID-based Ring Signature and Proxy Ring Signature Schemes from Bilinear Pairings [PDF]

, 2004
In 2001, Rivest et al. firstly introduced the concept of ring signatures. A ring signature is a simplified group signature without any manager. It protects the anonymity of a signer. The first scheme proposed by Rivest et al.

Deniable ring signature scheme based on the ISRSAC digital signature algorithm [PDF]

PeerJ Computer Science
This article introduces a deniable ring signature scheme within the framework of a ring signature protocol, which allows a member of the ring to assert or deny their role as the signature’s originator without the involvement of a trusted third party ...

Cryptanalysis of Lattice-Based Blind Signature and Blind Ring Signature Schemes [PDF]

IEEE Access, 2021
A blind signature enables a user to obtain signatures on any message from an authority who cannot acquire any information on the message being signed. A blind ring signature scheme is designed as a ring signature scheme with the blindness property.

Certificateless Linkable Ring Signature Scheme

IEEE Access, 2020
Ring signature is an anonymous signature that both authenticates the message and protects the identity information of the signer. It is suitable for scenarios such as anonymous network access, online auctions, etc.
