Zoom has announced the global availability of post-quantum end-to-end encryption (E2EE) for Zoom Meetings, with Zoom Phone and Zoom Rooms to follow soon.
Zoom shouldn’t be considered secure or private as there software has had security issues and there “end to end” encryption is just encryption to the server where it is decrypted.
I guarantee this quantum resistant encryption stuff is all snake oil.
What does post quantum even meaaan
If only there were some kind of article attached to the post that would explain it
I’m being sarcastic. It’s marketing bs.
The actual info is that the encryption is supposed to be quantum resistant which I doubt given quantum machines aren’t widely available to public so we don’t fully know their capabilities.
We have a pretty good idea. Post-quantum crypto is a real thing. There are conferences in the field about it.
Certain classes of problems are shown to be faster on quantum computers. One of them is factoring prime numbers, which is what our public key crypto is based on. Traditional block ciphers are also somewhat vulnerable, with their security is effectively cut in half. In other words, a 256 bit key is as secure as a 128 bit key. That solution is easy; we double the key size and call it a day. Public key crypto, however, is a bigger problem. Needed whole new algorithms.
The big unknown is how powerful quantum computers will get. It’s going to take a lot of qubits to break public key crypto. It may be completely unfeasible to juggle that many qubits in superposition. It’s also possible it will only barely do it, in which case we can also increase the key size and call it a day. But post-quantum crypto is being worked on, just in case.
Zoom is still bullshit. Their software has had all sorts of problems that don’t need QC to exploit.
Appreciate the info!

That’s absolutely the point I’m driving to. We basically have the eniacs of quantum sure we have an idea of what they can do now but 5-10 years down the road are solid mystery. In the spirit of that, to me, ‘post quantum’ is kinda of meaningless vaporware when we only just started with quantum computing. Maybe I’m being a dick about it but that’s my mindset for better or worse.

Agreed, fuck zoom.
we don’t fully know their capabilities.
Well, you don’t.
Out of all of the ways you could have responded, instead of fostering conversation and helping to educate someone, this is what you choose.
Oh well, makes me grateful for the other commentor since I can have a really good and enjoyable conversation with them. Bye Felicia.
Oh yeah, your comment was clearly good natured and looking for spirited discussion.
