On Anonymity of Group Signatures [PDF]
, 2005 A secure group signature is required to be anonymous, that is, given two group signatures generated by two different members on the same message or two group signatures generated by the same member on two different messages, they are indistinguishable except for the group manager.

, 2012 We initiate the study of unique group signature such that signatures of the same message by the same user will always have a large common component (i.e., unique identifier). It enables an efficient detection algorithm, revealing the identities of illegal users, which is fundamentally different from previous primitives.

A decentralized group signature scheme for privacy protection in a blockchain
International Journal of Applied Mathematics and Computer Science, 2021 Group signature schemes play a vital role in protecting identity privacy of a member of a group who signs a message using the group signature. However, in the existing group signature schemes the centralized group manager has control over all the ...

Group–Proxy Signature Scheme: A Novel Solution to Electronic Cash
Journal of Intelligent Systems, 2013 Proxy signature and group signature are two basic cryptographic primitives. Due to their valuable characteristics, many schemes have been put forward independently and they have been applied in many practical scenarios up to the present.
