Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for porting digital rights management services. In one aspect, a system includes: a hardware processor; one or more memory devices coupled with the hardware processor and effecting an operating system for the hardware processor; and a digital rights management (DRM) component having a DRM adaptor configured to check whether the hardware processor has a hardware-based encryption element, use the hardware-based encryption element if available, and use a software-based encryption element if the hardware-based encryption element is not available, wherein the software-based encryption element includes code compiled from source code for the hardware processor, the source code prepared for different computer platforms.
