Abstract
This invention provides a method for providing trusted display to security sensitive applications on untrusted computing platforms. This invention has a minimal trusted code base and maintains full compatibility with the computing platforms, including their software and hardware. The core of our invention is a GPU separation kernel that (1) defines different types of GPU objects, (2) mediates access to security-sensitive GPU objects, and (3) emulates accesses to security-sensitive GPU objects whenever required by computing platform compatibility.
