摘要： A method and apparatus for an iterative cryptographic block under the control of a CPU and without a fixed number of stages. In one embodiment, a first cryptographic block descrambles received information using an internal key or a preprogrammed key to form a descrambled key or descrambled data. A data feedback path stores the descrambled data as internal data and provides the internal data or the external data as data input to the first cryptographic block. A key feedback path stores the descrambled key as an internal key and provides the internal key or the preprogrammed key to a key input of the first cryptographic block. A second cryptographic block descrambles received content using a final descrambling key. Other embodiments are described and claimed.

摘要： In certain embodiments, a selective encryption encoder has a packet identifier that identifies packets of a specified packet type. The specified packet type includes packets carrying data representing a video slice wherein the video slice contains a larger amount of data than a threshold amount of data. A packet duplicator duplicates the identified packets to produce first and second sets of the identified packets. Packets are sent and received to and from a primary encryption encoder to encrypt the first set of identified packets under a first encryption method. A secondary encrypter encrypts the second set of identified packets under a second encryption method. This abstract should not be considered limiting since embodiments consistent with the present invention may involve more, different or fewer elements.
摘要翻译：在某些实施例中，选择性加密编码器具有标识指定分组类型的分组的分组标识符。指定的分组类型包括携带表示视频切片的数据的分组，其中视频切片包含比阈值数据量更大的数据量。分组复制器复制所识别的分组以产生识别的分组的第一组和第二组。数据包被发送和接收到主加密编码器，以在第一加密方法下对第一组标识的分组进行加密。辅助加密器以第二加密方法加密第二组标识的分组。该摘要不应该被认为是限制性的，因为与本发明一致的实施例可以涉及更多，不同或更少的元件。

摘要： A method of upgrading an encryption process for encryption of video information from an old encryption process to a new encryption process, consistent with certain embodiments involves selecting a portion of video content for selective encryption. The selected portion is duplicated to produce first and second copies of the selected portion. The first copy is encrypted using the old encryption process and the second copy is encrypted using the new encryption process to produce a dual partially encrypted segment of video information that can either be broadcast over a cable or satellite system or stored in a package medium as two program chains.

摘要： A multimedia stream head end includes a legacy conditional access (CA) device that fully encrypts the stream using legacy keys. A copy of the stream is sent to a secondary CA device that encrypts only critical packets in the stream using secondary keys to render a partially encrypted stream. The critical packets in the fully encrypted stream from the legacy CA device are obtained and inserted next to the corresponding critical packets in the partially encrypted stream. Thus, only critical packets are encrypted, with encrypted versions being generated by both the legacy CA and secondary CA without the legacy CA knowing which of the packets that it encrypts are “critical”.
