Abstract

In PKC 2014, Langlois et al. proposed the first lattice-based group signature scheme with the verifier-local revocability. The security of their scheme is selfless anonymity, which is weaker than the security model defined by Bellare, Micciancio and Warinschi (EUROCRYPT 2003). By using the technique in the group signature scheme proposed by Ling et al. (PKC 2015), we propose a group signature scheme with the verifier-local revocability. For the security discussion of our scheme, we adapt the BMW03 model to cope with revocation queries, since the BMW03 model is for static groups. Then, we show that our scheme achieves the full anonymity in the adapted BMW03 model.
