Since Bellare et al. (EUROCRYPT 2003) proposed a security model for group signature schemes, almost all the securities of group signature schemes have been discussed in their model (the BMW03 model). While the BMW03 model is for static groups, Bellare et al. in 2005 considered the case of dynamic group signature schemes and provided a solution to cope with dynamic groups. However, their scheme does not serve member revocation, serves only member registration. In this paper, we incorporate a member revocation mechanism into a group signature scheme with member registration and construct a fully dynamic group signature, which supports verifier-local revocation (VLR) to manipulate member revocation. Moreover, we achieve the security of the proposed scheme with a restricted version of full anonymity to overcome the security complications that may arise due to member revocation.
