Abstract: A gateway device is disclosed that includes a user key; a transceiver to communicate data over a network and with a set top box; and a processor configured for: receiving a protected secure key from a content provider; receiving an encrypted control word key from the content provider. The encrypted control word key is encrypted with a secure key and, once the encrypted control word key is decrypted, the decrypted control word key decrypts an encrypted digital content that is sent to a set top box; retrieving the user key from the memory of the gateway device; using the user key to decrypt the protected secure key to obtain a decrypted secure key; using the decrypted secure key to decrypt the encrypted control word key to obtain the decrypted control word key; and transmitting the decrypted control word key to the set top box for decrypting the encrypted digital content.
