Systems and methods of direct delivery of content descrambling keys using chip-unique code are described herein. One such method includes receiving a unique chip identifier from a digital subscriber communications terminal; determining a chip key associated to the chip identifier; encrypting a service instance using the chip key; and transmitting the encrypted service instance. One such system includes a chip key server configured to store a plurality of chip identifiers, each identifier associated with a chip key, and configured to receive a unique chip identifier from a digital subscriber communications terminal; and an encryptor configured to encrypt a service instance using the chip key associated with the unique chip identifier, the chip key provided by the chip key server.
