About us
The Cryptography & Graphs Research Group (C&G) in
Universitat de Lleida
constitutes a well-established research team with a track record of more
than 15 years of scientific activities. The team members in the C&G group
are part of the
Department of Mathematics
and the Polytechnic Institute of Research and Innovation in Sustainability
(InsPIReS).
Most members of the C&G group teach in the degree and the master of Computer
Science at the Escola Politècnica Superior
(EPS).
The research interests of the members in the C&G group lie between theory
and applications, mainly in the following two areas: Cryptography and
Graph Theory.
In the area of Cryptography, our research focuses on computational
aspects of algebraic curve cryptography and design of
secure cryptographic protocols for RFID technology, smart cards
and e-voting systems.
In the area of Graph Theory, our research concerns open problems on dense and
eccentric digraphs, extremal problems and privacy-preserving social
network data analysis.
The C&G group has been recognized by the Generalitat de Catalunya as:
- Emerging research group 2009 SGR 442.
- Consolidated research group 2014 SGR 1666.
- Consolidated research group 2017 SGR 1158.
- Consolidated research group 2021 SGR 00434.
The C&G group is part of the Cybersecurity Research Center of Catalonia
(Cybercat), lead by Josep
Domingo and constituted by the research groups in this field of the Catalan
universities.
