Abstract
The systems, methods and apparatuses described herein provide a computing environment that includes a secure zone for executing tasks. An apparatus according to the present disclosure may comprise a screen, a secure zone and an indicator operatively controlled by the secure zone. The secure zone may be configured to execute 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 screen to a non-secure zone while the apparatus is operating in a non-secure mode.
Claims23
An apparatus, comprising:
- a screen;
- an indicator;
- a non-secure zone;
- and
- a secure zone comprising:
- a non-volatile storage configured to store at least one digital certificate and at least one encryption key;
- a secure processor configured to execute a task comprising task certificate information representing a task signer;
- and
- a supervisor configured to:
- control access to the at least one digital certificate and the at least one encryption key;
- assume control over an output of the screen when the apparatus operates in a secure mode and to transfer control over the output of the screen to the non-secure zone when the apparatus operates in a non-secure mode;
- and
- control operation of the indicator, wherein the supervisor activates the indicator when the apparatus operates in the secure mode and deactivates the indicator when the apparatus operates in the non-secure mode.
A method of operating an apparatus, comprising:
- receiving a task, at a secure zone of the apparatus, from a non-secure zone of the apparatus, wherein the task comprises task certificate information representing a task signer;
- assuming control, by a supervisor of the secure zone, over an output to a screen of the apparatus;
- executing the task, by a secure processor of the secure zone, utilizing data stored in a memory of the secure zone, wherein the memory of the secure zone is inaccessible to the non-secure zone;
- activating, by the supervisor, an indicator of the secure zone when the task is being executed by the secure processor;
- and
- transferring control, by the supervisor, over the output to the screen to the non-secure zone after the task execution is complete.
