A REPLAY ATTACK RESISTANCE DRM SCHEME BASED ON PHYSICAL LEVEL FILE LOCATION

This paper tackles the problem of resisting the replay attack in digital rights management (DRM) systems. Commonly used measures rely on continuous online connection from the client to a trusted server or the existence of tamper-proof hardware, such as Trusted Platform Module (TPM). In our work, we create a virtual tamper-proof hardware simulation instead of a real one, and introduce the concept of Placeholder File (PF). The effectiveness of our scheme bases on the change of physical level PF location in the stable storage device. Our scheme focuses on the offline digital content usage, and the primary experiments demonstrate that our scheme is secure enough to be put into practice use.
