Abstract:
1. A method of communicating with a computing device having a trusted security zone, the method comprising: mapping a unique identifier for a computing device with a trust zone access control address, wherein the computing device comprises a normal security zone and a trusted security zone providing hardware assisted security that is separate from the normal security zone, wherein the trust zone access control address is unique to a hardware component of the trusted security zone within the computing device, and wherein when an application executes in the trusted security zone of the computing device, applications that are configured to execute in the normal security zone are prevented from executing on the computing device; composing, by a source external to the computing device, a message comprising the trust zone access control address, wherein the trust zone access control address is not discoverable from the computing device, and wherein the trusted zone access control address is different from the unique identifier; routing the message to the computing device based on the unique identifier, wherein the message is internally routed to the trusted security zone within the computing device using the trust zone access control address, and wherein the message is received by an application executing in the trusted security zone of the computing device; providing a second message to a second application on the computing device executing in the trusted security zone subsequent to routing; obtaining a response from the second application on computing device; and determining that the message was routed to the trusted security zone based on the response obtained from the second application.
