Splet31. jan. 2024 · Although currently several traceable (or linkable) ring signature schemes have been proposed, most of them are constructed on pairings. In this paper, we present an efficient traceable ring signature (TRS) scheme without pairings, which is based on the modified EDL signature (first proposed by D.Chaum et al. in Crypto 92). SpletDefinition 1 (Ring signature):A ring signature comprises four probabilistic polynomial-time (PPT) algorithms as follows: † Gen(1k): on input the security parameterk, outputs a common reference string l. † KeyGen(l) is run by the user: on input a common reference string l, outputs a public verification keyvand a private signing keysk.

SpletLinkable ring signatures are an important cryptographic tool as it protects signer anonymity and link signatures from the same signer. The linkable ring signature obtained from this transformation performs at par with the other lattice-based solutions for linkable ring signature, which does not require high-end zero-knowledge proofs.
