Host Device and Method for Super-Distribution of Content Protected with a Localized Content Encryption Key

A method for super-distribution of content, the method comprising:

• performing the following in a host device storing a super-distribution key and a content encryption key, the host device being in communication with a source storage device storing content encrypted with the content encryption key:
• creating a super-distribution token by encrypting the content encryption key with the super-distribution key;
• and
• storing the super-distribution token and the encrypted content retrieved from the source storage device in a target storage device.

A host device comprising:

• an interface through which the host device can connect to and communicate with a storage device storing content encrypted with a content encryption key;
• a memory storing a super-distribution token, wherein the super-distribution token comprises an encrypted version of the content encryption key;
• and
• a controller in communication with the interface and the memory, wherein the controller is operative to:
• provide the super-distribution token to a server, wherein the server is configured to generate an activation token from the super-distribution token, wherein the activation token contains the content encryption key;
• receive the activation token from the server;
• retrieve the content encryption key from the activation token;
• and
• decrypt the encrypted content received from the storage device using the content encryption key retrieved from the activation token.
