An efficient VM-based software protection
Amir Z. Averbuch, Michael Kiperberg, Nezer Jacob Zaidenberg · 2011
This paper presents Truly-protect, a system, incorporating a virtual machine, that enables execution of encrypted programs. Our intention is to form a framework for a conditional access/digital rights management system. We avoid relying on obscurity and rely only on assumptions about the system itself and on cryptographic measures to develop VM-based conditional access/trusted computing environment. Rolles in [18], proposes a general way of breaking systems of type described herein. We claim that Rolles' method fails to defeat our system.
