[Resource Topic] 2021/1406: Non-Slanderability of Linkable Spontaneous Anonymous Group Signature (LSAG)

Welcome to the resource topic for 2021/1406

Title:
Non-Slanderability of Linkable Spontaneous Anonymous Group Signature (LSAG)

Authors: Veronika Kuchta, Joseph K. Liu

Abstract:

In this paper, we formally prove the non-slanderability property of the first linkable ring signature paper in ACISP 2004 (in which the notion was called linkable spontaneous anonymous group signature (LSAG)). The rigorous security analysis will give confidence to any future construction of Ring Confidential Transaction (RingCT) protocol for blockchain systems which may use this signature scheme as the basis.
