Abstract:
A wireless communication device comprises first processing circuitry configured to execute an RF operating system and second processing circuitry configured to execute an open operating system, wherein the first processing circuitry is linked to a secure memory device inaccessible to the second processing circuitry. The RF operating system is configured to receive protected data and store the protected data in the secure memory device. The open operating system is configured to receive a request for the protected data from one of a plurality of user applications and transfer the request to the RF operating system. In response to the request for the protected data, the RF operating system is configured to retrieve the protected data from the secure memory device, encrypt the protected data, and transfer the encrypted protected data to the open operating system for delivery to the one of the user applications associated with the request.
