    Abstract: A process may be utilized by a DVR. The process characterizes a set of content as a plurality of segments as the set of content is received. Each of the segments has a segment length according to a predetermined time interval. Further, the process encrypts each of the segments with a corresponding content encryption key to generate a plurality of encrypted segments. The corresponding content encryption key for each of the segments is generated by the DRM component. In addition, the process stores each of the encrypted segments for playback with trick play features in accordance with an expiration content rule having a time limit on the temporary playability of the set of content.

    Abstract: A method is provided by which a client device obtains authorized access to content delivered over a content delivery network. The method includes receiving an entitlement management message (EMM). The EMM includes at least one cryptographic key and a device registration server certificate ID (DRSCID) identifying a currently valid device registration server (DRS) public key certificate. The DRSCID obtained from the EMM is compared to a stored DRSCID value. An entitlement control message (ECM), which includes an encrypted traffic key for decrypting content, is received. If the DRSCID obtained from the EMM is determined to match the stored DRSCID, the traffic key is decrypted with the cryptographic key or a key derived from the cryptographic key to thereby access the content.

    Abstract: A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.
