    摘要： In summary, ROM marks (such as wobbles, lateral deviations in the spiral with lands and pits in an optical disc) are used on optical media to ensure consumer-grade copying devices cannot duplicate original media. An additional level of security is that the detection of the side channel information requires knowledge of a certain secret, which must be hidden well in authorized players. If the secret leaks, a professional pirate will be able to detect the ROM mark and duplicate the original medium with the side channel information intact. The present invention proposes that instead of a single ROM mark, many ROM marks are applied to a disc. Further, devices are divided into groups, and each group has the capability to only detect one mark from the group. This way, if a secret is obtained from a device, the disc can be duplicated, but only a limited number of devices will be able to use this disc. Creating a disc that can be played in any device requires the hacking of one device from every group.

    摘要： A transmitter provides receivers conditional access to data transmitted via a network. A content encryptor is used to encrypt the data under control of a same authorization key before it is transmitted to all receivers. The transmitter has a storage with a plurality of device keys. A further encryptor is used for producing a key block with a plurality of entries, where each entry is associated with a respective one of the device keys. At least some of the entries contain a representation of the authorization key encrypted with the associated device key. The transmitter transmits the same key block to all receivers.The receiver has a subset of the device keys. A first decryptor is used to retrieve the authorization key by decrypting at least one entry of the key block that is associated with one of the device keys of the receiver. A second decryptor is used for decrypting the data under control of the authorization key.

    摘要： The present invention relates to a digital rights management system (40) for controlling access rights to copy protected content comprising an application unit (1, 21, 41) and a drive unit (3, 23, 43), to an application unit (1, 21, 41), to a drive unit (3, 23, 43) and to a corresponding digital rights management method. In order to allow an increased security in the management of digital rights, wherein in particular a “filter-driver”-hack is made impossible or is at least substantially complicated and a reliable confirmation about a command given in respect of digital rights and its execution, a digital rights management system (40) is proposed wherein said application unit (1, 21, 41) comprises a key storage unit (45) for storing a bus key (KB), a request generation unit (47) for generating a request (7, 27) to be carried out by said drive unit including a message regarding said access rights and a challenge (RX), a communication unit (51) for transmitting said request (7, 27) and for receiving a response (13, 33) to said request (7, 27) from said drive unit (3, 23, 43), a response verification unit (49) for verifying a link between said request (7, 27) and said response (13, 33) by decoding said response (13, 33) using said bus key (KB) and by checking for the presence of an indication of said challenge (RX) in said response (13, 33) and said drive unit (3, 23, 43) comprises a key storage unit (55) for storing a bus key (KB), a communication unit (51) for receiving a request (7, 27) including a message regarding said access rights and a challenge (RX) from said application unit (1, 21, 41) and for transmitting a response (13, 33) to said request (1, 21, 41), a request processing unit (57) for verifying said request (7, 27) and processing said message, a response generation unit (59) for generating said response (13, 33) including an indication of said challenge (RX) and a reply to said message, wherein said indication of said challenge (RX) and said reply are cryptographically linked by means of said bus key (KB) and wherein indication of said challenge (RX) in said response (13, 33) indicates that said request has been carried out.
