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.

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.

Linkable Ring Signature for Privacy Protection in Blockchain-Enabled IIoT [PDF]

Sensors
The blockchain-enabled industrial Internet of Things (IIoT) faces security threats such as quantum computing attacks and privacy disclosure. Targeting these issues, in this study, we design a new lattice-based linkable ring signature (LRS) scheme, which ...

Post-Quantum Revocable Linkable Ring Signature Scheme Based on SPHINCS+ for V2G Scenarios [PDF]

Sensors
As a core support for the integration of new energy and smart grids, Vehicle-to-Grid (V2G) networks face a core contradiction between user privacy protection and transaction security traceability—a dilemma that is further exacerbated by issues such as ...

Identity-Based Linkable Ring Signature Scheme

IEEE Access, 2019
A ring signature is an anonymous signature that implements both the authentication of the message and the anonymity of the signer. In a “normal” ring signature scheme, the same signer can generate multiple ring signatures, but the verifier ...

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.

On Design of Single-Layer and Multilayer Code-Based Linkable Ring Signatures

IEEE Access, 2020
In this paper, we present an effective code-based linkable ring signature scheme based on Borromean ring signature. The security of the scheme is based on the hardness of Syndrome Decoding problem, General Syndrome Decoding problem and Codeword Finding ...

Research Progress and Prospect of Ring Signatures [PDF]

Jisuanji kexue yu tansuo, 2023
As a special group signature, ring signature has been widely used in anonymous voting, anonymous deposit and anonymous transaction because it can not only complete the signature without the cooperation of ring members, but also ensure the anonymity of ...
