Abstract

A system includes a session and resource manager and a video pump. The session and resource manager negotiates encryption keys from a headend controller and provides the encryption keys to a video pump. The video pump uses the encryption keys from the session and resource manager to encrypt content. Thus, the video pump uses encryption keys to encrypt the content so that it is encrypted right from the video pump prior to transmission over the entire transport system. A generic modulation device may thus be used to modulate the encrypted content over the delivery network.
