E.g. a synth has a public key embedded. To change settings, you upload them to the vendor, who blesses them with their private key.
Hacking such a synth requires either jailbreaking the synth, or the vendor losing their key . Both can be mitigated with tamper resistant hardware.
We're well ahead on this path already, I assume AI will accellerate it. This is very bad news for the right to repair.
1) current encryption not available in the 1990's. These are the age of DES and weapon-grade vs commercial encryption. There was a legal cost blocking strong encryption.
2) Manufacturers were not as strongly opposed to people touching the internals. After WW2, most people could fix anything, because survival depended on it. Even in the 60's radios etc. came with schematics, and building your own was normal and cost-effective. The shift happened in the '90s, with governements requiring licensing for everything, and mass manufacturing making repair less cost effective than buying a new one.
Our current culture where only people blessed by the manufacturer are allowed to do anything is very recent.
