"A lot of stately homes will have that system," says Niki Johnson, fire systems technical adviser for the UK Fire Association, a trade body, and owner of fire detection firm Derventio Fire and Security. "You could be looking at £3-4,000 just to do a corridor." Such installations require substantial pipework, he explains.

The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today’s X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor’s algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site.
