A device receives a first data item. The device stores the first data item in non-volatile memory. The device subsequently receives a second data item, where the second data item was previously generated from the first data item and a cryptographic key. The device performs a function such as, for example, an exclusive-or operation on the first data item and the second data item to generate the cryptographic key. The device uses the generated cryptographic key to encrypt data which may be transmitted over a wireless interface.

Key provisioning

A handheld communications device is created with a touch sensitive display, a secure computing component, and a non-secure computing component. The secure component may comprise a secure CPU executing a secure operating system. The non-secure component may comprise a separate non-secure CPU executing a separate non-secure operating system. The touch sensitive display on the handheld communications device is divided into a secure portion and a non-secure portion such that information displayed in the secure portion is provided by the secure operating system, and information displayed in the non-secure portion is provided by the non-secure operating system. Similarly, data entered through the secure portion of the display is provided to the secure operating system, and data entered through the non-secure portion of the display is provided to the non-secure operating system.
