Abstract: A secure content delivery or access method may include coordination among three devices such as servers—a content management server, a delivery server, and an authorization server. A request for content may originate from an authorization server application, and may involve the application obtaining two digitally signed tokens for the request. The first token may be from the authorization server, and may include a content management server identifier for the requested content. The second token may include two identifiers for the content: the first identifier being the content management server identifier, and the second being a delivery server identifier. The first and second tokens may be signed by the authorization server and content management server, respectively, and may be delivered to the delivery server for validation. Successful validation may result in the delivery server providing a content decryption key for the requested content to a device requesting the content.
