摘要 |
<p>Disclosed is a method for receiving an encrypted broadcasting service by an access terminal in a mobile communication system including an access node for providing a broadcasting service to the access terminal over a radio channel and a packet data service node for connecting the access node to a broadcasting server via a packet data network. The method comprises receiving a mask parameter message including a mask value for reception of a desired broadcasting service, from the access node; receiving a broadcasting service packet including a masked seed and a broadcast security packet, from the access node over a radio broadcast channel; calculating a particular seed using the masked seed value and the mask value, and generating an encryption key using the calculated seed and a previously received broadcast access key; and decrypting the broadcast security packet using the encryption key. <IMAGE></p> |
