Proactive forced renewal of content protection implementations

An apparatus, comprising:

• a tangible, machine-accessible storage memory;
• and
• instructions in the machine-accessible storage memory which, when executed by a processing system, cause the processing system to perform operations comprising:
• on a first substantially periodic basis, automatically pushing a new content protection implementation to a device that contains an existing content protection implementation;
• wherein the existing content protection implementation comprises (a) existing software for presenting protected content and (b) an existing key to facilitate presentation of protected content;
• and
• wherein the new content protection implementation comprises a new key to supersede the existing key for facilitating presentation of protected content;
• and
• on a second substantially periodic basis, automatically pushing revocation data to the device, the revocation data to identify a plurality of revoked keys, each revoked key of the plurality of revoked keys comprising a key that has been superseded by the new key of the new content protection implementation;
• wherein the revocation data is automatically pushed to the device on the second substantially periodic basis only after a corresponding new content protection implementation has already been pushed to the device to equip the device with a replacement key for at least one of the plurality of revoked keys.

A device, comprising:

• a processor;
• a machine-accessible medium responsive to the processor;
• an existing content protection implementation comprising (a) existing software for presenting protected content and (b) an existing key to facilitate presentation of protected content;
• and
• instructions in the machine-accessible medium which, when executed by the device, enable to device to perform operations comprising:
• receiving a new content protection implementation pushed to the device, the new content protection implementation comprising a new key to supersede the existing key for facilitating presentation of protected content;
• replacing the existing key with the new key from the new content protection implementation;
• and
• after replacing the existing key with the new key from the new content protection implementation, receiving revocation data, wherein (a) the revocation data is pushed to the device and (b) the revocation data identifies a plurality of revoked keys, wherein at least one revoked key of the plurality of revoked keys has been superseded by the new key from the new content protection implementation.
