This paper presents a lattice-based group signature scheme that provides both member registration and member revocation with verifier-local revocation. Verifier-local revocation (VLR) seems to be the most suitable revocation approach for any group since when a member is revoked VLR requires to update only verifiers. However, presenting a fully dynamic and fully secured lattice-based group signature scheme with verifier-local revocation is a significant challenge. Thus, we suggest a new security notion to prove the security of VLR schemes with member registration. As a result, we present a dynamical-almost-fully secured fully dynamic group signature scheme from lattices with VLR.
