Abstract
An encryption key module in a content providing server receives a request to stream electronic media data to the user device. The encryption key module identifies a predefined shared secret key corresponding to a key in a subscriber identity module (SIM) in the user device. The predefined shared secret key is used for encryption of data. The encryption key module encrypts the requested electronic media data based on the shared secret key and provides the encrypted electronic media data to the user device over a wireless network.
