Upcoming seminar | Post-quantum Cryptography, A New Era

The Dean of the School of Mathematics and Physics, Professor Jintai Ding, has been invited to deliver a distinguished seminar at the Yukawa Institute for Theoretical Physics (YITP), Kyoto University, on 20 April 2026.

＊ Abstract:

Public key cryptosystems (PKC) serve as the security foundation of modern communication systems, most notably the Internet. However, Shor’s algorithm has demonstrated that existing PKCs—such as Diffie-Hellman key exchange, RSA, and ECC—could be compromised by quantum computers.
To prepare for the quantum age, it is essential to build new public key cryptosystems capable of resisting such attacks. In this lecture, Professor Ding will provide an introduction to Post-Quantum Cryptography (PQC) and its recent developments, with a specific focus on the NIST standardisation process and its global impact. He will also present a practical and provably secure key exchange protocol based on "Learning with Errors" (LWE) problems, highlighting its conceptual simplicity and robust security properties. The session will conclude with a discussion on the current landscape of PQC development and the migration strategies for modern infrastructure.
