摘要： Between a data recording/playback device and a data storage device, CBC-mode encryption processing is executed which encrypts a plurality of encryption keys of content which correspond to sectors. The encrypted data is stored in a header corresponding to the content. The CBC-mode encryption processing is executed by using a storage key unique to media in which the content is stored. For using the content, only by decrypting the key data in media in which mutual authentication is established, the content can be used, so that highly-secure key storage is implemented.

摘要： A content use rights discrimination card corresponding to encrypted content is sold to a user. The user transmits data recorded on the content use rights discrimination card to a content use rights management center. The content use rights management center then verifies the content and the card, based on data in the received content use rights discrimination card, to encrypt a decoding key for decoding the content together with, for example, a session key, to transmit the encrypted content key to the user. The content use rights discrimination card, when sold to the user, can be set for enabling resale and transferred between different users so that the decoding key can be transmitted plural times from the content use rights management center. This procedure enables content to be utilized without executing any on-line settlement processing.

摘要： There is provided a highly secure cryptographic processing apparatus and method where an analysis difficulty is increased. In a Feistel type common key block encrypting process in which an SPN type F function having a nonlinear conversion section and a linear conversion section is repeatedly executed a plurality of rounds. The linear conversion process of an F function corresponding to each of the plurality of rounds is performed as a linear conversion process which employs an MDS (Maximum Distance Separable) matrix, and a linear conversion process is carried out which employs a different MDS matrix at least at each of consecutive odd number rounds and consecutive even number rounds. This structure makes it possible to increase the minimum number (a robustness index against a differential attack in common key block encryption) of the active S box in the entire encrypting function.

摘要： A cryptographic processing unit divides and inputs constituent bits of data to be subjected to data processing to lines, and repeatedly performs a data converting operation using round functions on the data of the respective lines. The cryptographic processing unit inputs n/d-bit data obtained by dividing n-bit data as input data by a division number d to each line, and repeatedly performs a round calculation including a data converting operation using round functions. The n/d-bit data in each line having output data of the round calculations is divided into d/2 sets of data, and the divided data are combined to restructure d sets of n/d-bit data that are different from the output data of the round calculations of the previous stage. The restructured data is set as input data for round calculations of the next stage. The cryptographic processing realizes improved diffusion properties and a high level of security.

摘要： A processing unit transforms first input information into first nonlinear transformed information that is transformed into first linear transformed information, and transforms second input information into second nonlinear transformed information that is transformed into second linear transformed information. An exclusive- or section performs an exclusive- or operation based on the first and second linear transformed information. When the first nonlinear and linear transformed information are expressed as a first and second sequence vector, respectively, and the second nonlinear and linear transformed information are expressed as a third and fourth sequence vector, respectively, then a first row vector chosen from a first inverse matrix of a first matrix that transforms the first sequence vector to the second sequence vector, and a second row vector chosen from a second inverse matrix of a second matrix that transforms the third sequence vector to the fourth sequence vector, are linearly independent.
