German Saez Moreno

German Saez Moreno is a Professor in the Department of Mathematics at the Universitat Politècnica de Catalunya (UPC), affiliated with the Barcelona School of Telecommunications Engineering. He is a core member of the ISG-MAK (Information Security Group - Mathematics Applied to Cryptography) and the MAK research group. His work focuses on cryptography, information security, and their applications in cybersecurity and distributed systems.

Research Interests:

• Cryptography and cryptanalysis of advanced cryptographic protocols
• Secret sharing schemes and access structure design
• Secure communication protocols and post-quantum cryptography
• Distributed key management and self-healing systems
• Cybersecurity education and curriculum development

Recent Publications Trends: His 2025 work on (k,n)-consecutive access structures advances secret sharing theory. Recent projects (2023-2022) emphasize cybersecurity education and post-quantum cryptographic solutions. Earlier contributions (2010-2005) include foundational work on threshold schemes, proxy signatures, and self-healing key distribution mechanisms.

Grants & Projects: Lead researcher in multiple competitive R&D projects including 'Criptografía para retos digitales emergentes' (2022), 'Hacia una sociedad digital segura' (2014), and EU-funded 'European Network of Excellence for Cryptology II' (2010). Active in curriculum innovation through the SPACE project (2023).

Lab/Team: Co-leads the ISG-MAK group focusing on applied cryptography and information security solutions.
