S04 : Ep. 11 : Post-Quantum Cryptography: Designing Cybersecurity Beyond Quantum Computing, Featuring Craig Costello

About this episode

The episode explores the implications of quantum computing on cybersecurity and the development of post-quantum cryptography with expert Craig Costello.

In this episode, we go quantum! Our host Rashan Senanayake sits down with Professor Craig Costello, a leading cryptographer from Queensland University of Technology and former Microsoft Research scientist, to demystify how cryptography quietly secures our everyday digital lives, from emails, online banking, and messaging apps to the global systems we rely on, and why these foundations must evolve as quantum computing becomes a reality, exploring what post-quantum cryptography really means, how quantum computers threaten today’s cybersecurity standards, how quantum-resistant global security frameworks are being developed, and why mathematics, education, and early exposure to STEM remain critical to shaping a secure digital future for education, technology, government, and business alike.
