摘要： An information processing apparatus utilizing encrypted information corresponding to content of purchased right, includes a memory for storing the encrypted information, usage control policy indicating content of purchased right and price tag for specifying price content corresponding to the content of the purchased right. A first generating device generates a usage control status including the purchase history of the information on the basis of the usage control policy and the price tag stored in the memory. A setting device sets usage history based on usage of the information to the usage control status. A second generating device calculates an accounting price and generates accounting information including the accounting price based on the purchase history or the usage history, and/or puts a limit on purchasable usage conditions based on the purchase history or the usage history on the occasion the right is purchased again on different format from the control policy.

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.

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： It is possible to realize a Feistel-type common key block encryption/decryption processing configuration capable of reducing data stored in a memory at a low cost. The Feistel-type common key block encryption/decryption processing repeatedly executes an SP-type F function having nonlinear and linear transform sections by several rounds. At least one of the nonlinear and linear transform processes executed in the F function in each round is executed as a transform process identical with a transform process applied to an encryption/decryption algorithm other than a Feistel-type common key block encryption/decryption algorithm and/or another hash function such as AES and Whirlpool. With this configuration, it is possible to reduce the design cost and the amount of data stored in a memory.
