A presentation by Prof Bill Buchanan OBE on the increasing risk that Post Quantum Computers pose to cryptography.

Watch the video



Public key encryption plays a key part in our digital world, including in the creation of secure encryption tunnels, proof of identity, and in creating digital signatures. Unfortunately, quantum computers will break all of your existing public key encryption. NIST, though, has been defining a range of Post Quantum Cryptography (PQC) methods and which will replace our existing methods.

This talk will outline the risks involved, and possible migration strategies, along with an outline in how PQC methods actually work. Along with this, we will see some of the opportunities that quantum computers will supply in cybersecurity.
