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 12):
The device as claimed in  claim 10 , the device comprising a trusted execution environment configured to implement at least in part steps (c) to (i) and a rich execution environment configured to provide the encrypted content key to the trusted execution environment in time for the next portion to be decrypted.
