摘要：
A communication system includes a head end. The head end communicates with a system gateway. A plurality of user devices is coupled to the gateway. The gateway receives the plurality of first encrypted signals, decrypts the plurality of first encrypted signals to form unencrypted signals and encrypts the unencrypted signals with a second encryption to form a plurality of second encrypted signals and communicates the second encrypted signals to the plurality of user devices. The signals may also be super-encrypted signals. That is, rather than un-encrypting at the gateway, the first encrypted signals may be again encrypted.
