摘要： A computer system having resistance to timing attacks based on measuring processing times is offered. The computer system encrypts or decrypts a plain text or ciphertext via a process of converting the partial data on the plain text or the encrypted text into conversion data. A conversion table includes one piece of conversion data corresponding to the partial data at the start position of the line table area and includes data not associated with the conversion in the other position. A computer program includes: an operation instruction group for calculating the predetermined position of the corresponding conversion data in the conversion table by using the acquired partial data; and a read instruction group for reading out the conversion data from the position calculated from the conversion table.

摘要： Processing load on an executing device for conducting playback is high during the playback of contents since the executing device performs verification of the contents validity in parallel with the contents playback, and therefore the executing device has to be equipped with a highly efficient processor. The present invention reduces the processing load involved in the verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on the DVD. In addition, the present invention is capable of improving the accuracy of detecting unauthorized contents to some extent by randomly selecting a predetermined number of encrypted units every time the verification is performed.
摘要翻译：由于执行装置与内容重放并行地执行内容有效性的验证，所以在内容的重放期间，用于进行再现的执行装置上的处理负载很高，因此执行装置必须配备高效率的处理器。本发明通过仅使用构成在DVD上记录的加密内容的多个加密单元随机选择的预定数量的加密单元来验证验证。此外，本发明能够通过每次执行验证时随机选择预定数量的加密单元，来在一定程度上提高检测未授权内容的准确性。

摘要： The data encryption apparatus with a data converting unit splits 256-bit input data into 32-bit data blocks A1, B1, A2, and B2. A first combining unit performs an exclusive OR operation on A1 and B1, and on A2 and B2. A first scramble unit branches A1, A2, and the results of the exclusive OR operations (C1 and C2) into three data blocks each, and for each set of three data blocks, shift-rotates two of the data blocks and combines the shifted data blocks with the remaining data block. A second combining unit performs an exclusive OR operation on D1 and E2, and on D2 and E1, which are the results of the processing performed by the first scramble unit. A block concatenating unit concatenates the results of the operations performed by the second combining unit. A second scramble unit branches the concatenated data into three data blocks, shift-rotates two of the data blocks and combines the two shifted data blocks with the remaining data block.
