Sadly, another attempt will likely be made at some point. At least the regulation is quite explicit:
> This Regulation shall not prohibit, make impossible, weaken, circumvent or otherwise undermine cybersecurity measures, in particular encryption, including end-to-end encryption, implemented by the relevant information society services or by the users. This Regulation shall not create any obligation that would require a provider of hosting services or a provider of interpersonal communications services to decrypt data or create access to end-to-end encrypted data, or that would prevent providers from offering end-to-end encrypted services.
As all post-quantum crypto is relatively new there is still the risk of it being broken in the future. This is why we combine the new algorithms with classical ones in an hybrid approach so that the encryption stays at least as secure as it is now.
SIKE was known to be breakable since at least 1997, specific breaking algorithms were developed in 2000, and these were implemented in Magma (a symbolic algebra suite from John Cannon, Sydney Uni, second generation after the original Cayley system of the mid 1980s).
It wasn't a choice that would have been put forward by people in the abstract algebra game - just something put forward as a 'candidate' by security researchers.
Learn some math, more specifically learn abstract algebra | read current papers in the field, befriend people active in the field that have taken over from Charles Leedham-Green, George Havas, et al is good practical advice to avoid using methods already known for decades to be weak.
It answers the question.
> Learn some decency.
Little rude, given the question asked was answered.
A (regular) steel beverage can is pretty thin, and comes with sharp edges on the opener ring/tab? (I suppose the tab could be plastic - but they're not now)
This doesn't seem to be a very hard problem to me. In the sense that you don't need to invent any new tech to store personal info. I also don't see a reason why these models will not run locally on our devices in the future.
