摘要

A networking system comprising an application service that runs on a cloud infrastructure and is configured to receive dual encrypted content from a content provider and re-encrypt the dual encrypted content to enable dynamic user group control for group-based user authorization, and a cloud storage service coupled to the application service and configured to store the dual encrypted content from the content provider and the re-encrypted dual encrypted content from the application service, wherein the application service and the storage service are configured to communicate and operate with a content delivery service that uses a content delivery network (CDN) to deliver the re-encrypted content to one or more users in a group authorized by the content provider.
