Cryptography and Cybersecurity

The Cryptography and Cybersecurity section specializes in foundational and applied research to secure digital systems. We focus on cryptographic methods for building systems that protect data privacy, ensure integrity, and defend against real-world threats.

Our researchers develop precise models for reasoning about the security properties of computer systems. They design mathematically sound encryption techniques, authentication mechanisms, and cryptographic protocols that support secure distributed and decentralized systems.

The section combines expertise in secure multiparty computation, zero-knowledge proofs, post-quantum cryptography, and cryptographic engineering to tackle challenges in digital identity, blockchain, privacy-preserving machine learning, secure e-voting, and more.

We aim to advance both the theoretical foundations and practical applications of cybersecurity through foundational research, algorithmic improvements, and analysis of real-world systems.

We collaborate with industry and public institutions to create meaningful solutions, from mitigating vulnerabilities in critical infrastructure to shaping the future of secure digital communication.

By bridging theory and practice, the section contributes to a safer and more resilient digital society.
