Abstract
Techniques for encrypting content in a content distribution network are disclosed. The content distribution network may comprise a number of national and local sites, and a number of hubs at each local sites. A content segment encrypting device may be operative at a local site to encrypt and cache segments of content. The segment encrypting device may provide the segments to streaming devices that encode content for delivery downstream to network or user devices.
