Stronger security notions for decentralized traceable attribute-based signatures and more efficient constructions (2015)
Journal Article
Ghadafi, E. (2015). Stronger security notions for decentralized traceable attribute-based signatures and more efficient constructions. Lecture Notes in Artificial Intelligence, 9048, 391-409. https://doi.org/10.1007/978-3-319-16715-2_21

© Springer International Publishing Switzerland 2015. 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 three dimensions: Firstly,...

Efficient Distributed tag-based encryption and its application to group signatures with efficient distributed traceability (2015)
Journal Article
Ghadafi, E. (2015). Efficient Distributed tag-based encryption and its application to group signatures with efficient distributed traceability. Lecture Notes in Artificial Intelligence, 8895, 327-347. https://doi.org/10.1007/978-3-319-16295-9_18

© Springer International Publishing Switzerland 2015. 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 requiring an...
