Abstract: A secure integrated circuit (IC) to provide access to an electronic storage, the secure IC including a memory and a processor. The processor may generate a first key and a second key, and enable storing the first key in the memory and storing the second key in a device memory of a device. The processor may then receive the second key from the device when the device wants to access the electronic storage, and grant the device access to the electronic storage by using the first key and the second key received from the device.

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.
