Publishing content in connection with digital rights management (DRM) architecture

A method in combination with a digital rights management architecture wherein a packager packages digital content for a user and a licensor issues a digital license to the user for the content, the user rendering the content only in accordance with the license, the packager having provisioning content from the licensor including a shared Secret encrypted according to a random content key (KD-PROV) ((KD-PROV(Secret)));

• and a provisioning license from the licensor including (KD-PROV) encrypted according to a public key of the packager (PU-PA2) ((PU-PA2(KD-PROV))), the method for the packager to package the content for the user such that the licensor can issue the license to the user and comprising:
• selecting the provisioning license and provisioning content from the licensor;
• obtaining (PU-PA2(KD-PROV)) from the provisioning license;
• applying a corresponding private key of the packager (PR-PA2) to (PU-PA2(KD-PROV)) to result in (KD-PROV);
• obtaining (KD-PROV(Secret)) from the provisioning content;
• applying (KD-PROV) to (KD-PROV(Secret)) to result in the shared Secret;
• generating a random content ID for the content;
• calculating a content key (KD) based on the random content ID and the Secret;
• encrypting the content according to, (KD) ((KD(Content)));
• obtaining from one of the provisioning license and the provisioning content a provisioning content ID having an identifier of the licensor;
• appending to (KD(Content)) the random content ID, a public key of the packager (PU-PA1), and the identifier of the licensor to form the packaged content;
• and
• distributing the packaged content to the user.

A method in combination with a digital rights management architecture wherein a packager packages digital content for a user and a licensor issues a digital license to the user for the content, the user rendering the content only in accordance with the license, the packaged content including the content encrypted according to a content key (KD) ((KD(Content))), a content ID, and a public key of the packager (PU-PA1), the method for the licensor to issue the license to the user and comprising:

• receiving a request for a license from the user, the request including the content ID, (PU-PA1), and a public key associated with the user (PU-US) that is to be employed to bind the license to the user, the user having a corresponding private key (PR-US);
• obtaining based on (PU-PA1) stored provisioning information regarding the packager including a Secret shared therewith;
• calculating (KD) based on the content ID received with the request and the obtained Secret;
• encrypting (KD) according to (PU-US) as received with the request ((PU-US(KD)));
• appending to (PU-US(KD)) the content ID to form the license;
• and
• sending the license to the user.
