d/v-CLSAG: Extension for Concise Linkable Spontaneous Anonymous Group Signatures

sowle

Abstract

In this paper we present a Schnorr-like linkable ring signature scheme we call d/v-CLSAG that is extension for d-CLSAG scheme. The proposed extension allows the use of different group generators for different layers of the ring members, while the original scheme assumes the use of the same generator G across all layers. We provide the security statements for the proposed updated scheme. This work was reviewed by the Cypher Stack.
