Nicknames for Group Signatures
Nicknames for Group Signatures (NGS) is a new signature scheme that extends Group Signatures (GS) with Signatures with Flexible Public Keys (SFPK). Via GS, each member of a group can sign messages on behalf of the group without revealing his identity, except to a designated auditor.

Secure Obfuscation for Encrypted Group Signatures
PLOS ONE, 2015 In recent years, group signature techniques are widely used in constructing privacy-preserving security schemes for various information systems. However, conventional techniques keep the schemes secure only in normal black-box attack contexts. In other words, these schemes suppose that (the implementation of) the group signature generation algorithm is

Quasi-Efficient Revocation of Group Signatures [PDF]
, 2003 A group signature scheme allows any group member to sign on behalf of the group in an anonymous and unlinkable fashion. In the event of a dispute, a designated trusted entity can reveal the identity of the signer. Group signatures are claimed to have many useful applications such as voting and electronic cash.

Lattice-Based Group Signatures with Logarithmic Signature Size [PDF]
, 2013 Group signatures are cryptographic primitives where users can anonymously sign messages in the name of a population they belong to. Gordon {\em et al.} (Asiacrypt 2010) suggested the first realization of group signatures based on lattice assumptions in the random oracle model.

Splitting Groups of Signature (1;n)
Journal of Algebra, 1996 It is an old problem whether the Fuchsian group \(G=\langle a,b:[a,b]^n=1\rangle\), \(n\geq 2\), of signature \((1;n)\) has a decomposition as a free product with amalgamation. Using a suitable representation of \(G\) in \(\text{PSL}_2(\mathbb{Q}_p)\), where \(\mathbb{Q}_p\) denotes the \(p\)-adic rationals, and the Bass-Serre theory on groups acting ...

, 2008 Group signatures make it possible for group members to sign messages on behalf of the group, while not revealing the signer's identity. Only the group's revocation manager, who is in possession of a secret key for signature opening, can identify the signer.

Group-level signatures in bonobo sociality
Evolutionary Human SciencesAbstract Humans show remarkable differences in social behaviour between families, groups, communities and cultures, whereas such group-level within-species variation in socio-behavioural propensities is typically overlooked in other species. Studies on intraspecific variation in animal social structures are needed to inform an evolutionary account ...

Efficient group signature and identity-based signature schemes [PDF]
, 2019 This document focuses the cryptographic schemes. Some new signature schemes are proposed. The proposed schemes provides better performance than the previous counterparts. DOCTOR OF PHILOSOPHY (EEE)

Proceedings of the 2006 ACM Symposium on Information, computer and communications security, 2006 We propose a novel group-oriented signature scheme, called a democratic group signature (DGS). In DGS the scheme setting is controlled on a contributory basis, i.e., without any centralized trusted authority (group manager). Group members agree on a common tracing trapdoor, i.e., every member can trace issued signatures individually.
