Em um esquema de assinatura de anel vinculável, o próprio signatário seleciona um conjunto de partes chamado "anel" e assina as mensagens em nome do anel. Qualquer parte pode saber se as assinaturas são ou não feitas pelo mesmo signatário, embora a parte não possa saber a identidade do verdadeiro signatário. Au, Liu, Susilo e Yuen propuseram um esquema de assinatura em anel vinculável baseado em ID e um esquema de assinatura em anel vinculado revogável-iff baseado em ID. Com um esquema de assinatura em anel vinculado a iff revogável, qualquer parte pode recuperar a identidade do signatário, se o signatário fizer duas ou mais assinaturas em anel. Neste artigo, mostramos que o esquema de assinatura em anel vinculado a iff revogável de Au et al. não fornece anonimato, mesmo que o signatário faça apenas uma assinatura em anel. O anonimato é um dos requisitos de segurança mais básicos das assinaturas em anel.

Abstract: In a linkable ring signature scheme, a signer himself selects a set of parties called a "ring" and signs the messages on behalf of the ring. Any party can know whether or not the ring signatures are made by the same signer, although the party cannot know the identity of the actual signer. Au, Liu, Susilo, and Yuen proposed an ID-based linkable ring signature scheme and an ID-based revocable-iff-linked ring signature scheme. With a revocable-iff-linked ring signature scheme, any party can recover the identity of the signer, if the signer makes two or more ring signatures. In this paper, we show that Au et al.'s revocable-iff-linked ring signature scheme does not provide anonymity, even if the signer makes only one ring signature. Anonymity is one of the most basic security requirements of ring signatures.

AB - In a linkable ring signature scheme, a signer himself selects a set of parties called a "ring" and signs the messages on behalf of the ring. Any party can know whether or not the ring signatures are made by the same signer, although the party cannot know the identity of the actual signer. Au, Liu, Susilo, and Yuen proposed an ID-based linkable ring signature scheme and an ID-based revocable-iff-linked ring signature scheme. With a revocable-iff-linked ring signature scheme, any party can recover the identity of the signer, if the signer makes two or more ring signatures. In this paper, we show that Au et al.'s revocable-iff-linked ring signature scheme does not provide anonymity, even if the signer makes only one ring signature. Anonymity is one of the most basic security requirements of ring signatures.
