New Lock Aims To End Chip Piracy
I also thought immediately of this. They dont even have to disassemble it. The article implies the main way that knockoff fabs get their plans are by blueprints. So chip manufacturers are going to produce chips that have DRM because they cant keep their blueprint designs safe. Makes a hell of a lot of sense....
If a knockoff gets the blueprints, its fairly trivial to figure out where the DRM stuff is located and they can modify their fab process so that it doesnt include them.
