摘要
Examples of a system, method, and apparatus for encrypting and recording content are presented. When content is recorded to storage media, the content is encrypted with a content instance key. This content instance key is encrypted with the public key of a first set-top box and a duplicate of the content instance key is encrypted with the public key of other than said first set-top box. A private key corresponding with the public key of the first set-top box may be used to decrypt the content instance key, or a private key corresponding to the public key of other than the first set-top box may be used to decrypt the duplicate of the content instance key so that the encrypted content from the removable storage media may be made available in the clear.
