Post Quantum Cryptography: An Introduction in Plaintext - Lucy Bell

With the UK National Cyber Security Centre setting out timelines for migration to post-quantum cryptography - including completing discovery and planning by 2028 - the quantum future is no longer theoretical. Quantum computing may still seem abstract, but its impact on classical cryptography is real. This talk explains the mathematics behind today’s encryption, how quantum computing threatens it, why data stolen today could be decrypted tomorrow, and how your organisation can start preparing now.
