Abstract: Disclosed are various embodiments providing a portable wireless communication device that includes a secure element configured to route a set of input/output (I/O) channels to host processing circuitry of a mobile communication device. The secure element includes an application executable by the secure element, the application being configured to obtain a policy via an I/O channel of the set of I/O channels. The application is further configured to prevent the host processing circuitry from accessing data corresponding to at least a portion of the set of I/O channels according to the policy.

Abstract: Methods and systems for authentication of a device are disclosed. An exemplary method includes transmitting an energy towards the device including a material, monitoring a response of the device to the transmitted energy, generating a signature of the device based on the response of the device to the transmitted energy, comparing the device signature to an enrolled signature for the device, and indicating that authentication of the device is successful when the generated signature matches the enrolled signature. An exemplary system includes a transmitter configured to transmit an energy towards the device, a receiver configured to monitor a response of the device, and a processor configured to generate a signature of the device based on the response of the device, compare the device signature to an enrolled signature for the device, and indicate that authentication of the device is successful when the generated signature matches the enrolled signature.
