Abstract
Multimedia content may be delivered to content consumer devices via a content-delivery network. Encrypted content and cryptography keys for decrypting the content may be distributed from a data center to various nodes of the content-delivery network, each node acting as a semi-independent content-delivery system. Each content-delivery system is capable of delivering received content to end-users and implementing a key-management scheme to facilitate secure content-delivery and usage tracking, even when the content-delivery system is disconnected from the data center. In other words, the disclosed systems and methods facilitate the operation of nodes which may operate in “autonomous mode” when disconnected from a larger content-delivery network, thus maintaining content-delivery capabilities despite having little if any connectivity to external networks.
