A Lattice-based Linkable Ring Signature Scheme for Blockchain Privacy Protection
Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed ComputingThis paper presents a new blockchain scheme using a linkable ring signature algorithm based on lattice cryptography. This scheme counters quantum attacks on blockchain transaction signatures.

Adding Linkability to Ring Signatures with One-Time Signatures
2019We propose a generic construction that adds linkability to any ring signature scheme with one-time signature scheme. Our construction has both theoretical and practical interest. In theory, the construction gives a formal and cleaner description for constructing linkable ring signature from ring signature directly.

A Linkable Ring Signature Scheme on Lattice from DualRing
2024 6th International Conference on Electronics and Communication, Network and Computer Technology (ECNCT)In today's privacy-conscious world, considering the possible problems of duplicate voting and duplicate payments in voting systems, payment systems and other application scenarios, linked ring signature (LRS) is a reliable option to ensure the need for ...

A Linkable and Convertible ID-based Ring Signature
2011 International Conference on Computational and Information Sciences, 2011Digital signatures have been widely used in our life, and many variants of digital signatures have been studied these years. Ring signature is one of the variants that pro-vides anonymity for signers. Ring signature has a non-central structure, and it is suitable to achieve in ID-based cryptography(IBC)where public keys can be used before corresponding

Ring Signature with Weak Linkability and Its Applications
IEEE Transactions on Knowledge and Data Engineering, 2008We suggest a linkable ring signature scheme providing strong anonymity and weak linkability. We show that our linkable ring signature scheme can be used to construct a selectively linkable ring signature scheme, an efficient convertible (verifiable) ring signature scheme, and an efficient deductible ring signature scheme.

Identity Based Linkable Ring Signature with Logarithmic Size
2021Anonymity is an inevitable and sensitive matter of concern, especially in the age where people are willing to use digital devices and Internet to deal with almost all things in their work and daily life. To support anonymity, modern cryptography is one of the most suitable choices in the algorithm level. Particularly, in the scenarios, such as e-voting,

A Code-Based Linkable Ring Signature Scheme
2018Linkable ring signature schemes are cryptographic primitives which have important applications in e-voting and e-cash. They are ring signature schemes with the extra property that, if the same user signs two messages, a verifier knows they were signed by the same user. In this work, we present a new linkable ring signature scheme.

Triptych: Logarithmic-Sized Linkable Ring Signatures with Applications
2020Ring signatures are a common construction used to provide signer ambiguity among a non-interactive set of public keys specified at the time of signing. Unlike early approaches where signature size is linear in the size of the signer anonymity set, current optimal solutions either require centralized trusted setups or produce signatures logarithmic in ...

Escrowed Linkability of Ring Signatures and Its Applications
2006Ring signatures allow a user to sign anonymously on behalf of a group of spontaneously conscripted members. Two ring signatures are linked if they are issued by the same signer. We introduce the notion of Escrowed Linkability of ring signatures, such that only a Linking Authority can link two ring signatures; otherwise two ring signatures remain ...
