Abstract

A packager packages digital content for a user and a licensor issues a digital license to the user for the content such that the user renders the content only in accordance with the license. The licensor and packager share a Secret to allow the packager and the licensor to calculate a content key (KD) for the content. To package the content for the user, the packager calculates a content key (KD) based on the shared Secret and a content ID and encrypts the content according to (KD). To issue a license to the user for the content, the licensor also calculates (KD) based on the shared Secret and the content ID, encrypts (KD) according to a public key of the user to form the license, and sends the license to the user.
