A New Constant-Size Group Signature Scheme From Lattices
IEEE Access, 2020 A lattice-based group signature scheme (LGSS) is an active cryptographic primitive, where each group member can sign messages anonymously in the name of the entire group and each valid signature should be traced to some group member on the lattice.

Ring Signature With Unconditional Anonymity in the Plain Model
IEEE Access, 2021 Ring signature allows a user to sign messages as a member of a set of users, which is called the ring. In addition to an unforgeability, ring signature ensures that nobody can detect which member in the ring signs the message.
