Kill Cell

Bruce Schneier warns about an innocuous sounding idea called Digital Manners Policy. While some of the ideas sound interesting and address some serious problems, the difficulty in getting this right could not be overstated. From Bruce Schneier’s article:

The possibilities are endless, and very dangerous. Making this work involves building a nearly flawless hierarchical system of authority. That’s a difficult security problem even in its simplest form. Distributing that system among a variety of different devices — computers, phones, PDAs, cameras, recorders — with different firmware and manufacturers, is even more difficult. Not to mention delegating different levels of authority to various agencies, enterprises, industries and individuals, and then enforcing the necessary safeguards.

Once we go down this path — giving one device authority over other devices — the security problems start piling up. Who has the authority to limit functionality of my devices, and how do they get that authority? What prevents them from abusing that power? Do I get the ability to override their limitations? In what circumstances, and how? Can they override my override?

Hopefully this idea will stay in the lab where it belongs.
