Stopping counterfeit LV bags is hard because there's no authentication mechanism short of putting RFID tags in each bag. But a computer accessory is different.

Stopping counterfeit LV bags is hard because there's no authentication mechanism short of putting RFID tags in each bag.
But a computer accessory is different. The magsafe charger communicates with the laptop using the 1-wire protocol[0][1]. Why not incorporate an authentication mechanism here?

- btrask 11y agoMy counterfeit Dell charger (with 1Wire) just died after working great for 2 years (although yes, it was probably dangerous). Because of DRM I couldn't attach the plug to a different power supply (as shown to me by an EE I trust). Now I'm in the crappy situation of either rewarding Dell by buying a safe adapter, or taking my business elsewhere with another counterfeit, which might burn my house down.
