Abstract
An apparatus implementing a secure zone on one or more virtual machines may be provided. In one aspect, the apparatus may comprise a screen and a computer processor. The computer processor may be configured to initialize a hypervisor, establish a first virtual machine under the control of the hypervisor and execute code for a secure zone thereon, and establish a second virtual machine under the control of the hypervisor and execute code for a non-secure zone thereon. The code for the secure zone may be configured to initiate executing a task, and to assume control over an output to the screen while the apparatus is operating in a secure mode and to transfer control over the output to the non-secure zone while the apparatus is operating in a non-secure mode. The hypervisor may be configured to grant requests from the secure zone to assume and transfer control over the output.
