Abstract:
Devices, servers, systems and methods for content protection are provided. Disclosed embodiments improve temporal granularity of controlling access to the protected content and increase resilience against attacks attempting to prevent re-evaluation of conditions of access. Enforcement of re-evaluation may be based on the receipt and/or verification of tokens. In some embodiments, re-evaluation is enforced by periodically rendering content keys required for content decryption unuseable and/or clearing content keys already in use.

Claim (Index 15):
A server for controlling decryption of encrypted media content in a client device remote from the server, the server comprising a processing environment configured to:\n send an encrypted content key and an access condition message to the client device, wherein the client device decrypts the content key to decrypt the media content with the content key; evaluate a server-side condition to determine whether the client device should be able to continue to use the content key to decrypt the media content; and
