We provide a formal security model for traceable attribute-based signatures. Our focus is on
the more practical case where attribute management is distributed among different …

In this work, we first formalize the notion of dynamic group signatures with distributed
traceability, where the capability to trace signatures is distributed among n managers without …

Abstract Direct Anonymous Attestation (DAA) is one of the most complex cryptographic
protocols deployed in practice. It allows an embedded secure processor known as a Trusted …

Abstract With Attribute-based Signatures (ABS) users can simultaneously sign messages
and prove compliance of their attributes, issued by designated attribute authorities, with …

Often we are less concerned with who signed something than with what attributes (director
of this company etc.) they have. We propose three Attribute Based Signature schemes …

Abstract" Attribute-based Signatures (ABS) are a powerful tool allowing users with attributes
issued by authorities to sign messages while also proving that their attributes satisfy some …

The notion of group signatures was introduced to allow group members to sign
anonymously on behalf of a group. A group manager allows a user to join a group, and …

In this work, we revisit the notion of Decentralized Traceable Attribute-Based Signatures
(DTABS) introduced by El Kaafarani et al.(CT-RSA 2014) and improve the state-of-the-art in …

Attribute-based signatures allow a signer owning a set of attributes to anonymously sign a
message wrt\some signing policy. A recipient of the signature is convinced that a signer with …
