Abstract:
In some embodiments, the invention involves securing sensitive data from mal-ware on a computing platform and, more specifically, to utilizing virtualization technology and protected audio video path technologies to prohibit a user environment from directly accessing unencrypted sensitive data. In an embodiment a service operating system (SOS) accesses sensitive data requested by an application running in a user environment virtual machine, or a capability operating system (COS). The SOS application encrypts the sensitive data before passing the data to the COS. The COS makes requests directly to a graphics engine which decrypts the data before displaying the sensitive data on a display monitor. Other embodiments are described and claimed.
