Arc3D: A 3D Obfuscation Architecture

In DRM domain, the adversary has complete control of the computing node - supervisory privileges along with full physical as well as architectural object observational capabilities. Thus robust obfuscation is impossible to achieve with the existing software only solutions. In this paper, we develop architecture level support for obfuscation with the help of well known cryptographic methods. The three protected dimensions of this architecture Arc3D are address sequencing, contents associated with an address, and the temporal reuse of address sequences such as loops. Such an obfuscation makes the detection of good tampering points infinitesimally likely providing tamper resistance. With the use of already known software distribution model of ABYSS and XOM, we can also ensure copy protection. This results in a complete DRM architecture to provide both copy protection and IP protection.
