Abstract
The methods and systems described herein provide for securing sensitive information using a hypervisor-trusted client, in a computing device executing a hypervisor hosting a control virtual machine and a non-trusted virtual machine. A user of a non-trusted virtual machine requests to establish a connection to a remote computing device. Responsive to the request, a control virtual machine launches a client agent. A graphics manager executed by the processor of the computing device assigns a secure section of a memory of a graphics processing unit of the computing device to the client agent. The graphics manager renders graphical data generated by the client agent to the secure section of the graphics processing unit memory.
