"Post-quantum secure group signature with verifier local revocation and" by Shuaining Gao, Xinjian Chen et al.
Group signature supports users to generate signatures on behalf of the group. Verifier local revocation (VLR) is an important method to revoke a misbehaving user in group signature, which has attracted many researchers’ attention. However, the existing lattice-based group signature schemes with VLR either achieve only selfless anonymity, have revocation list of size linear with the number of revoked users, or suffer from the issue that signatures generated by revoked users could easily be linked by an adversary. Additionally, the development of quantum computing technology threatens the secu...
