> sAT Protocol (s@) is a decentralized social networking protocol based on static sites. Each user owns a static website storing all their data in encrypted JSON stores.
Cryptographically, a problem is that it makes ciphertexts publicly enumerable, protected by a X25519-derived key. This makes it very vulnerable to harvest-now-decrypt-later attacks, if you believe quantum computing will ever happen.
... and you don't believe that everything will be totally fucked when it does happen.
If there is a global passive observer, and they get quantum computing, a huge amount of supposedly encrypted private information just got popped. Whether or not I care about my dinky little private social network posts when every ssl/tls connection I've ever made is being cracked and data mined is an interesting question.
It's basically PGP + RSS, only mapped to a bunch of files of specific structure. Those could be RSS/ATOM feeds instead of JSON, to reuse an existing format. The reuse of the ideas is good, these ideas are time-proven.
As any PGP-lookalike, this thing has the key distribution problem, and won't scale to billions of users due to that. Key rotation and revocation is another problem. But for a small-scale network it should be fine, and can run on very tiny, very low-power devices, maybe even with intermittent connectivity.
Not true, the "content key" is common to all viewers of all posts, from a particular author. (hence the need to re-encrypt the world when you unfollow someone...)
