摘要： A data protection system is provided that reduces, to a degree, the amount of encrypted data that is distributed to a plurality of terminals. In the data protection system a terminal whose decryption keys are exposed by a dishonest party is made to be unable to decrypt the data correctly, while other terminals are able to decrypt the data correctly.The data protection system includes a plurality of terminals, and an encryption device that encrypts distribution data distributed to each terminal. Each terminal is corresponded with one node on a lowest level of a 4-ary tree structure or the like having a plurality of hierarchies. The data protection system, for each node in the tree structure, excluding those on the lowest level, determines a plurality of combination patterns that include combinations of two or more of all four nodes that are reached one level below the node, decides an individual decryption key for each determined combination pattern, and decides an individual decryption key for each node on the lowest level. Further, the data protection system has each terminal store all decryption keys decided for the nodes on the path from the node on the lowest level that corresponds to the terminal through to the node on the highest level. The data protection system prescribes nodes that are reached from the node on the lowest level that corresponds to the terminal through to the node on the highest level that correspond to a terminal that has been dishonestly analyzed as invalid nodes. For invalid nodes, other than invalid nodes on the lowest level, the data protection system designates an encryption key that corresponds to the decryption key decided in correspondence with the combination pattern that combines all nodes, excluding invalid nodes, of the four nodes that are reached one level below the node, and has the encryption device encrypt distribution data that uses each of the designated encryption keys.

摘要： An authentication system is provided having a revocation list generation apparatus that constructs and stores a revocation list in a tree structure, the revocation list generation apparatus being used in combination with a revocation judgment apparatus. The authentication system improves upon conventional authentication systems because the memory capacity to store a Certificate Revocation List (CRL) in order to identify revoked certificates is reduced. The tree structure corresponds to public key certificate, which are identified by leaf identifies, and nodes from a leaf that corresponds to a revoked public key certificate.

摘要： A recording/reproduction device 10 receives content broadcast from a content provision device 11. The recording/reproduction device 10 encrypts the received content using a device key, to generate first encrypted content. The recording/reproduction device 10 decrypts the first encrypted content to obtain the content, performs an image conversion on the obtained content to generate converted content, and encrypts the converted content using a medium key to generate second encrypted content. The recording/reproduction device 10 writes the second encrypted content, the medium key, and the device key to a portable medium 14. When the portable medium 14 is inserted in a mobile information terminal 15, the mobile information terminal 15 decrypts the second encrypted content using the medium key to obtain the converted content, and reproduces the converted content.

摘要： A system, which minimizes a time delay caused by one device being unable to access a recording medium until access by another device ends, when transcoding is performed by distributed processing, includes a main device transcoding each coded piece allocated to itself from among a plurality of coded pieces of a digital stream, and writing a transcoding result onto the recording medium, in a pipeline. While the recording device is performing the transcoding and the writing, an auxiliary device transcodes each coded piece allocated to itself one by one. Having completed the transcoding of all coded pieces allocated to itself, the auxiliary device transmits its transcoding results to the recording device and has the recording device write the transcoding results onto the recording medium which is a copy destination.

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

摘要： The present invention provides a password recovery system that re-supplies a password to only the legitimate user of the password. The password recovery system includes a memory card with CPU and a mobile phone. When a password needs to be recovered, a phone call is made, to the mobile phone, from a telephone connected to a phone line whose phone number is registered in advance into the memory card with CPU. The mobile phone then obtains the telephone number of the phone line via a caller's telephone number notifying service. It is judged whether the obtained telephone number and the registered phone number are the same, and when they are the same, the password stored in the memory card with CPU will be re-supplied so that the user can recover it.
