For data that needs long term security and confidentiality - there’s a risk of ‘hack-today, crack-tomorrow’ attacks, where key exchanges and digital signatures made today could be at risk of retrospective attacks, that will be possible once capable quantum computers are available.
Global action to develop Post-Quantum Cryptography is underway, and we’re at the heart of it because, if a quantum-enabled economy is going to emerge, it’ll need a secure digital infrastructure. Our quantum technology approach brings together the best of UK and international collaboration, and sees us working as a key contributor to the UK National Quantum Technologies Programme.
We’re working on Quantum Key Distribution (QKD), a secure key establishment technology available today that provides a secure communication method for exchanging encryption keys only known between shared parties, across an authenticated but insecure channel.
We’ve already created and built a quantum secured network pilot, connecting London with the M4 business corridor using the latest technologies, and we continue to turn quantum innovation into services for customers. EY became our first commercial customer to connect quantum secure data transmission between its major London offices.
