- The paper provides the first formal rigorous security model for fully dynamic group signatures where members can join and leave at any time. The work also unveils some weakness in existing security models which could lead to attacks related to traceability of signatures of some existing constructions following existing models. Group signatures are a central cryptographic primitive and has many real-world applications. The work has changed the state-of-the-art of security modelling of dynamic group signatures. Our model has been extensively adopted by various subsequent constructions. An extended version of the paper will appear in Journal of Cryptology.
