Abstract:
1. A method for a mobile communication device to indicate activity across operating domains of the mobile communication device, the method comprising: establishing a plurality of operating domains for the mobile communication device each operating as an independent virtual machine, wherein at least one of the operating domains is a high-side domain and at least another of the operating domains is a low-side domain; establishing a plurality of isolated regions of memory within a memory of the mobile communication device; assigning each of the plurality of operating domains to one of the plurality of isolated regions of memory; implementing a communication control module within the mobile communication device to enforce communication restrictions between software associated with each of the operating domains and user interface hardware of the mobile communication device; providing a trusted indicator on the mobile communication device for indicating activity in the high-side domain, the activity including at least one of an incoming call, an incoming text, or a new email, the trusted indicator configured to activate a user notification to indicate the activity, wherein the trusted indicator is under exclusive control of software associated with the high-side domain; providing an input on the mobile communication device for switching from the low-side domain to the high-side domain, the input configured as an input only device that is activated by user input; and providing a trusted element for the mobile communication device that is independent of either the high-side domain or the low-side domain, the trusted element configured to:
