摘要： A system and method for providing enhanced security for Over The Air (OTA) firmware changes defers decryption of a firmware image until it is transferred into a protected internal memory of a wireless device. An updated firmware image is encrypted at a source and transmitted to a wireless device having a processor, internal memory, and external memory. The wireless device stores the encrypted firmware image in its external memory. In response to receiving an instruction to load a new firmware image, the processor retrieves the encrypted firmware image from the external memory. The processor decrypts the encrypted firmware image and programs the internal memory in accordance with the decrypted firmware image.

摘要： A control system comprises an interface configured to receive a content request from a request source wherein the content request identifies content stored on a storage medium. The control system also comprises a processing system coupled to the interface and configured to process the content request to determine when the request source is a valid destination for the content based on a first identifier stored with the content. The interface is further configured to transfer the content to the request source when the request source is a valid destination.
