Abstract

A method for authorizing media content transfer between a home media server and a client device and provisioning DRM credentials on the client device, the method comprising receiving a service authorization credential at a client authorization server from a PKI provisioning server, wherein the service authorization credential is associated with a client device, and sending a validation response from the client authorization server to the PKI provisioning server if the client authorization server determines that the service authorization credential was previously provided by the client authorization server to the client device, wherein the validation response releases the PKI provisioning server to send DRM credentials to the client device.

First claim

What is claimed:

1. A method of provisioning DRM credentials on a client device, comprising:
receiving a provisioning request at a home media server from a client device, wherein said provisioning request comprises a service authorization credential;
validating said provisioning request at said home media server by sending an activation request to a client authorization server, wherein said activation request comprises said service authorization credential;
receiving an activation response at said home media server if said client authorization server validates said provisioning request by verifying said service authorization credential;
downloading DRM credentials to said home media server from a PKI provisioning server if said home media server received said activation response;
saving DRM certificate identifiers associated with said DRM credentials to said home media server; and
sending a provisioning response from said home media server to said client device, wherein said provisioning response comprises said DRM credentials.

2. The method of claim 1 , further comprising passing said DRM certificate identifiers from said home media server to said client authorization server.

3. The method of claim 2 , wherein said DRM credentials are DTCP-IP certificates and keys.

4. The method of claim 1 , wherein said provisioning request comprises device authentication credentials received by said client device from said PKI provisioning server.

5. The method of claim 1 , wherein said service authorization credential was received by said client device from said client authorization server prior to the client device sending said provisioning request.

6. The method of claim 1 , wherein said service authorization credential was locally generated on said client device by encrypting a subscriber identifier.

7. The method of claim 6 , wherein said client authorization server verifies said service authorization credential by extracting said subscriber identifier and checking said subscriber identifier against records associated with said client device at said client authorization server.
