A Deep Copy Protection Framework for Electronic Devices within Home

We present an attack to current interface copy protection systems and a new framework to restrict contents flowing within legal devices. The attack is named as interface replacement attack, which is motivated by the fact that a damaged interface usually can be replaced with a small cost. The new framework deploys security mechanisms in both interior part of a consumer electronic device and interfaces on it. We name it as deep copy protection framework to distinguish the current interface-centric copy protection frameworks. We believe that this viewpoint is novel and can be further studied to develop new copy protection system.
