ePrint Report: Efficient Linkable Ring Signatures: New Framework and Post-Quantum Instantiations

Yuxi Xue, Xingye Lu, Man Ho Au, Chengru Zhang

In this paper, we introduce a new framework for constructing linkable ring signatures (LRS). Our framework is based purely on signatures of knowledge (SoK) which allows one to issue signatures on behalf of any NP-statement using the corresponding witness. Our framework enjoys the following advantages: (1) the security of the resulting LRS depends only on the security of the underlying …
