Why every VPN should use post-quantum encryption

At the moment, a virtual private network (VPN) is a great way to protect your data from hackers. It offers sophisticated encryption that will keep your data hidden from third parties, including cyber criminals, government bodies, and advertisers.

However, not even all the best VPNs offer protection that’s future-proofed. You may not be aware of them yet, but there are already highly sophisticated quantum computers that use quantum physics to render their computations significantly more efficient than those performed by classical computers. Because of their superior processing power, these quantum computers have the ability to break encryption methods used to protect most of the data on the internet, including the algorithms used by a lot of VPNs.

There’s no need to panic just yet, as quantum computers are currently only being used for research purposes, meaning they can only be found in universities, science labs, and supercomputer centers. But once they become more widely available and powerful enough to break encryption, there will be catastrophic consequences for cyber security across the globe. This day is referred to as Q-day and experts predict it’s likely to happen in the next five years.

Luckily, some VPNs are already offering post-quantum encryption to protect your data now and in the future. But the ones that don’t offer this will become vulnerable to attack once Q-day happens. 

Therefore, it’s vital that all VPNs start investing in post-quantum cryptography to give their users the best level of protection possible.

In this guide, we’ll explain the threat of quantum computers in a lot more detail and recommend VPNs with post-quantum encryption.

There’s no need to panic just yet, as quantum computers are currently only being used for research purposes, meaning they can only be found in universities, science labs, and supercomputer centers.

And those quantum computers are incapable of breaking any kind of encryption at the moment. The reason quantum computing isn't mainstream yet is because the technology doesn't work. Quantum computing still has to overcome its interference, error correction, and scalability problems. A few months ago, the Google CEO said quantum computing is still a decade away, and some physicists say that's an optimistic outlook.

You mean I do not have to fear someone driving through the neighborhood with a data center trying to crack my VPN.

With that said... Proton is offering free Android service...

Proton VPN is free to use on Android without an account: here is what you need to know:

Rule of thumb for free services. If you are using a free service, you are not the customer, you are the product.

I agree, but I think it is just promotional towards folks using their email service. I have a free Proton email account and it is great. But of course they would rather have me sign up for premium. But like the article states, the VPN service is limited and you have to upgrade if you want better. So it is a “draw” item. A promotional sample...

re: “Quantum computing still has to overcome its interference, error correction, and scalability problems.”

Should remind one of the early hype surrounding ‘tunnel diodes’, diodes exhibiting the Esaki diode effect, a negative resistance in their V-I characteristic ... they were forecast to enable some aspects of high speed computing at the time (early 60’s).

We don’t use them today (in computers!) although Tektronix made widespread use of them in Oscilloscope triggering circuits for multiple decades ...

And I doubt my home system could handle such speed coming into it.
