ABSTRACT:
A communication system comprises a content provider system configured to receive a content request indicating content and a device identifier, determine a first key based on the device identifier, process the content using the first key to modify the content from an unprotected state to a protected state, and transfer the content in the protected state. The communication system further comprises an end user system configured to receive the content in the protected state and process the content with a second key to modify the content from the protected state to an unprotected state wherein the second key is internally hard coded to the end user system.
