Abstract: A method for providing mobile subscription content access is disclosed. Initially, subscription contents are stored in a server. The subscription content can be accessed via any terminal coupled to the server by a communication link. In response to an access to any of the subscription contents on an encrypted subscription channel via a terminal, a determination is made as to whether or not a valid receiver is found in the proximity of the terminal. If a valid receiver is found in the proximity of the terminal, an encryption/decryption key is transferred to the valid receiver. With the encryption/decryption key, the subscription contents on an encrypted subscription channel can be accessed via the terminal and the valid receiver.
