Research Overview

Post-Quantum Cryptography (PQC) encompasses cryptographic schemes designed to remain secure even after large-scale quantum computers become a reality. Classical public-key systems—most notably RSA and elliptic-curve cryptography (ECC)—are expected to be vulnerable; Shor’s algorithm, for example, can efficiently factor integers and solve discrete logarithms, mathematically undermining RSA and ECC. To prepare for this imminent threat, governments and organisations worldwide are accelerating the adoption of PQC.

Our laboratory pursues a research agenda in PQC that spans the full development lifecycle: from the design of encryption and digital-signature schemes, through rigorous security proofs and parameter selection, to high-performance implementations and real-world applications.
