Abstract
In one embodiment, a host device creates a super-distribution token by encrypting a content encryption key with a super-distribution key and stores the super-distribution token and encrypted content retrieved from a source storage device in a target storage device. In another embodiment, a host device provides a super-distribution token to a server, wherein the server is configured to generate an activation token from the super-distribution token, receive the activation token from the server, retrieve a content encryption key from the activation token, and decrypt encrypted content received from a storage device using the content encryption key retrieved from the activation token.
