    • A method of decrypting a scrambled digital data item at a client is disclosed, the method including: receiving actual control messages at the client, wherein each actual control message includes control word generating information for generating a control word associated with the actual control message; storing the actual control messages at the client; receiving the scrambled digital data item at the client independently of the actual control messages, wherein the scrambled digital data item includes a plurality of segments of scrambled digital data, each segment of scrambled digital data being associated with one of the actual control messages and being scrambled with the control word associated with the one of the actual control messages, and wherein the scrambled digital data item further includes a plurality of reference control messages, each segment of scrambled digital data comprising one of the reference control messages, each of the reference control messages including a control message reference value identifying the actual control message associated with the segment of scrambled digital data; and decrypting the scrambled digital data item using the plurality of actual control messages.
    • 公开了一种在客户端解密加扰的数字数据项的方法,所述方法包括:在客户端处接收实际控制消息,其中每个实际控制消息包括用于生成与实际控制消息相关联的控制字的控制字产生信息; 将实际控制消息存储在客户端; 在客户端独立于实际的控制消息接收加密的数字数据项,其中加密的数字数据项包括多个加扰的数字数据段,加扰的数字数据的每个段与实际控制消息中的一个相关联并被加扰 其中所述控制字与所述实际控制消息中的一个相关联,并且其中所述加密数字数据项还包括多个参考控制消息,所述加扰数字数据的每个段包括所述参考控制消息之一,所述参考控制消息中的每一个 包括识别与加扰的数字数据的段相关联的实际控制消息的控制消息参考值; 以及使用所述多个实际控制消息来解密所述经加扰的数字数据项。
