摘要
Securely sharing content between a first system and a second system is provided. A hardware-based root of trust is established between the first system and a server. Content requested by a user and an encrypted license blob associated with the content is received by the first system from the server. A first agent on the first system connects with a second agent on the second system. The encrypted license blob and a sub-license request are sent from the first agent to a security processor on the first system. The first security processor decrypts the encrypted license blob, validates the sub-license request, and if allowed, creates a sub-license to allow the second system to play the content. The first security processor sends the sub-license to a security processor on the second system. The first system provides access to the content to the second system for future playback according to the sub-license.
