Abstract
A protected graphics module can send its output to a display engine securely. Secure communications with the display can provide a level of confidentiality of content generated by protected graphics modules against software and hardware attacks.
Claims29
A method comprising:
- sending an output from a protected graphics module to a display engine, wherein said module is part of a graphics processor, said module to assert correctness of execution to a remote party, and said module only executable on said graphics processing unit;
- displaying the output on a display screen using the display engine;
- and
- enabling the display engine to enter the protected graphics module.
1 more element
One or more non-transitory computer readable media storing instructions executed by a processor to perform a sequence comprising:
- providing a secure output from a protected graphics module to a display engine, wherein said module is part of a graphics processor, said module to assert correctness of execution to a remote party, and said module only executable on said graphics processing unit;
- displaying the output on a display screen using the display engine and;
- enabling the display engine to enter the protected graphics module.
An apparatus comprising:
- a storage:
- and
- a processor, coupled to the storage, to provide a secure output of a protected graphics module for display on a display screen, using a display engine, wherein said module is part of a graphics processor, said module to assert correctness of execution to a remote party, and said module only executable on said graphics processing unit, to said display engine to enter the protected graphics module.
