Sebastia Martin Mollevi

Sebastia Martin Mollevi is a researcher at the Department of Mathematics, Universitat Politècnica de Catalunya, affiliated with the Information Security Group - Mathematics Applied to Cryptography (ISG-MAK). His work focuses on cryptographic protocols, secret sharing, and elliptic curve applications.

• Education: PhD in Mathematics (2000) from UPC, thesis on Elliptic Curves over ZN and Cryptographic Applications.
• Research Interests: Cryptography, secret sharing schemes, broadcast encryption, elliptic curve cryptography, combinatorial code design, and information theory applications.
• Publications: 108 activities including 16 indexed journal articles, 58 conference presentations, and 17 technical documents.
• Projects: Lead researcher in projects like Cátedra CARISMATICA and Criptografía para retos digitales emergentes, focusing on digital society security and post-quantum cryptography.

His work includes algorithmic improvements in broadcast encryption trade-offs, linear threshold secret sharing, and secure public-key cryptosystems. Notable contributions involve proving security equivalences in elliptic curve systems and developing practical encryption mechanisms.
