This survey reviews the two most prominent group-oriented anonymous signature schemes
and analyzes the existing approaches for their problem: balancing anonymity against …

Lattice-based group signature is an active research topic in recent years. Since the
pioneering work by Gordon et al.(Asiacrypt 2010), eight other schemes have been …

Abstract Structure-preserving signatures (SPS) are signature schemes where messages,
signatures and public keys all consist of elements of a group over which a bilinear map is …

Lattice-based group signature is an active research topic in recent years. Since the
pioneering work by Gordon, Katz and Vaikuntanathan (Asiacrypt 2010), ten other schemes …

Group signatures are an important anonymity primitive allowing users to sign messages
while hiding in a crowd. At the same time, signers remain accountable since an authority is …

Abstract We introduce Multimodal Private Signature (MPS)-an anonymous signature system
that offers a novel accountability feature: it allows a designated opening authority to learn …

In a group signature scheme, users can anonymously sign messages on behalf of the group
they belong to, yet it is possible to trace the signer when needed. Since the first proposal of …

Abstract Vehicular Ad hoc Network (VANET) is a versatile and ad hoc network, where the
vehicles must be authenticated before sharing any critical information. During …

If everyone were to use anonymous credentials for all access control needs, it would be
impossible to trace wrongdoers, by design. This would make legitimate controls, such as …

Group signature is a fundamental cryptographic primitive, aiming to protect anonymity and
ensure accountability of users. It allows group members to anonymously sign messages on …
