Cryptographic signature schemes are integral to secure and automated distribution of software products/updates -- providing source authentication and proof-of-data integrity. However, existing schemes are based on mathematics vulnerable to quantum computer attack. With quantum computers now becoming a commercial reality, there is an **urgent need for quan...

Data centres, and the networks and systems that surround them are the future work horse of digitised economies. The data processing that they provide is a well-known driver for economic growth, providing cutting edge storage and computing systems that increasingly underpin all aspects of business and society. These data centres are huge system of systems,...

Public key cryptography (PKC) is fundamental to the security of digital communications. Existing PKC standards rely on the difficulty of factoring integers (RSA) or calculating discrete logarithms (Diffie-Hellman/Elliptic-Curves). However, these 'hard problems' are easily broken by emerging quantum computers, creating an imminent security threat. With qua...

Post-quantum cybersecurity: A project that will help prepare the UK for the post-quantum cybersecurity era when a fully functioning quantum computer becomes available. But what's wrong with a quantum computer? Nothing is wrong with it, except that it is conceptually different from a conventional/classical computer and can, therefore, perform some types of...
