New design sets a high standard for post-quantum readiness.
Great. Now we just have to get Signal off AWS and we be good.
Signal puts a lot of effort into their threat model that assumes a hostile host (i.e. AWS). That’s the whole point of end to end encryption, even if the host is compromised the attackers do not get any information. They even go as far as padding out the lengths of encrypted messages so everyone looks like they are sending identical blocks of data
I’m assuming that they were more referring to the outage that occurred today that pulled a ton of the internet services, including signal offline temporarily.
You can have all the encryption in the world, but if the centralized data point that allows you to access the service is down, then you’re fucked.
no matter where you host, outages are going to happen… AWS really doesn’t have many… it’s just that it’s so big that everyone notices - it causes internet-wide issues
Monero, Nostr, Lemmy, and Mastodon did not go down. Why? Because they are decentralized
that’s pretty disingenuous though… individual lemmy instances go down or have issues regularly… they’re different, but not necessarily worse in the case of stability… robustness of the system as a whole there’s perhaps an argument in favour of distributed, but the system as a whole isn’t a particularly helpful argument when you’re trying to access your specific account
centralised services are just inherently more stable for the same type of workload because they tend to be less complex, less networking interconnectedness to cause issues, and you can focus a lot more energy building out automation and recovery than spending energy repeatedly building the same things… that energy is distributed, but again it’s still human effort: centralised systems are likely to be more stable because they’ve had significantly more work put into stability, detection, and recovery
Having in mind we are not even close to breaking classical cryptography with quantum computing I doubt this was their best investment of time
Once quantum computers break classical cryptography, it’s going to be too late to develop post-quantum cryptography, mate.
The best time to develop resilience is right now.
the best time was yesterday. the next best time is today. securing systems after they’re broken, when data could actively be collected prior to the breakthrough, is not the way to approach security.
