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 Polit├Ęcnica 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.
