Description:
Quantum computers won't be enough to break encryption, Cloudflare believes.

FULL STORY ======================================================================

Cloudflare has announced that all websites and APIS served through its platform will now support a post-quantum hybrid key agreement.

The service, which is now in beta, strives to protect encrypted internet traffic from computers powerful enough to break today's encryption - quantum computers.

The new is on by default, meaning theres no need for an opt-in: if the browser/app supports it, the connection to Cloudflares network will be secure from any future quantum computers trying to break the encryption and
eavesdrop on the transitioning traffic such as passwords . Quantum computers on the horizon

The service is also free of charge, the company said, adding that
post-quantum security should be the new baseline for the Internet.

Were still a long way from a fully-functioning, commercial-oriented quantum computer that could be used for such nefarious purposes. In fact, Cloudflare doesnt expect such a device to be around before 2037 at the earliest. But it has decided to integrate post-quantum encryption solutions to get ahead of
the curve and have enough time to solve any problems and weaknesses that
might come along - and the company is expecting at least some.

Even though the protocols used to secure the Internet are designed to allow smooth transitions like this, in reality, there is a lot of buggy code out there: trying to create a post-quantum secure connection might fail for many reasons for example, a middlebox being confused about the larger
post-quantum keys and other reasons we have yet to observe because these post-quantum key agreements are brand new, the company said. Read more

Its because of these issues that we feel it is important to deploy post-quantum cryptography early, so that together with browsers and other clients we can find and work around these issues.

Cloudflare also added that the solution will be something of a hybrid, as it eases into the transition: To start, this is new cryptography: even with
years of scrutiny, it is not inconceivable that a catastrophic attack might still be discovered. That is why we are deploying hybrids: a combination of a tried and tested key agreement together with a new one that adds post-quantum security. These are the best endpoint protection services today
