Recent years have witnessed the trend of leveraging cloudbased services for large scale content storage, processing, and distribution.

These algorithms allow CloudSeal to cache the major part of a stored cipher content object in the delivery network for content distribution, while keeping the minor part in the cloud storage for key management. The separation of subscription-based key management and confidentiality-orie...
