Abstract

A system and method for delivering content to end users encrypted within a content delivery network (CDN) for content originators is disclosed. CDNs transport content for content originators to end user systems in a largely opaque manner. Caches and origin servers in the CDN are used to store content. Some or all of the content is encrypted within the CDN. When universal resource indicators (URIs) are received from an end user system, the CDN can determine the key used to decrypt the content object within the CDN before delivery. Where there is a cache miss, an origin server can be queried for the content object, which is encrypted in the CDN.
