摘要： A user i calculates authentication application information involving a random-number parameter and transmits it to a sales company A. At the sales company A, the received authentication application information is one-way transformed using a random-number parameter and is transmitted to the user i as authentication challenged information. At the user i, an identification number for credit membership of the user and a password are inputted and the received authentication challenge information is transformed using the password to create authentication response information. Then the identification number of the user i and the authentication response information are transmitted to the sales company A. At the sales company A, the received authentication response information is one-way transformed so that the random-number parameter is cancelled so as to produce authentication reference information. Then the received identification number and the authentication reference information are transmitted to the credit company b. At the credit company b, transformed secret information which is stored in advance is retrieved using the received identification number as a key and it is determined whether the transformed secret information and the authentication reference information are equal. If they are equal, the credit company b transmits to the sales company A authentication information indicating correctness of the user i, and if they are not equal, it transmits authentication information indicating that the user i can not be authenticated as a correct user. At the sales company A, the authentication information transmitted from the credit company b is transmitted to the user i.

摘要： An authentication communication system is capable of storing information relating to revoked devices in less area than is conventionally required.A computer unit stores in advance revocation information that indicates at least one revoked apparatus, and when authenticating a driver unit judges, based on the revocation information, whether or not the driver unit is revoked. The computer unit prohibits communication with the driver unit when the driver unit is judged to be revoked, and communicates with the driver unit when the driver unit is judged not to be revoked.

摘要： In an information input/output system, a user device inputs and outputs information to and from external sources including a key management device. The system includes the key management device that securely outputs invalid-device information specifying an invalid device unit that has been made invalid for use, and the user device that includes an input/output unit and a host unit. Via the input/output unit, input and output of information is enabled between the host unit and the external sources. The host unit securely receives, via the input/output unit, the invalid-device information outputted by the key management device and judges whether or not the input/output unit is an invalid device unit by referring to the received invalid-device information. When judging, that the input/output unit is an invalid device, the host unit thereafter prohibits input and output via the input/output unit. Due to this construction, the host unit can correctly judge whether or not the input/output unit is an invalid device unit.

摘要： An encryption transmission apparatus and an encryption reception apparatus avoid attack that takes advantage of a re-transmission request. A server apparatus encrypts a content key five times, thereby generating five encrypted content keys, calculates a hash value of the content key, and transmits the five encrypted content keys and the hash value. An image playback apparatus receives the five encrypted content keys and the hash value, decrypts the five encrypted content keys thereby generating five content keys, calculates hash values, each corresponding to the generated content keys, and compares the calculated hash values with the received hash value, respectively. If at least one of the five calculated hash values matches the received hash value, the corresponding content key is considered correct. Conversely, if none of the five calculated hash values matches the received hash value, it is considered a decryption error.

摘要： A system structured from a management device, a content key distribution device and a plurality of terminals suppresses the data volume of a terminal revocation list (TRL). The management device generates and transmits a TRL formed from data that expresses terminal IDs of all terminals to be invalidated, by only a value and a position of a common bit string in the IDs, to the content key distribution device. Each terminal holds a terminal ID that includes a manufacturer ID and a serial number, and requests the distribution of a content key by sending the terminal ID to the content key distribution device. The content key distribution device refers to the TRL, judges whether the terminal ID transmitted from the terminal is that of an invalidated terminal, and if negative, encrypts and transmits the content key to the terminal.

摘要： A positional information storage system stores and verifies positional information of a mobile terminal apparatus. The positional information storage system stores (i) the positional information, (ii) time information, and (iii) signature data that is generated by placing a digital signature on a combination of the time information and the positional information of the mobile terminal apparatus only if a user of the mobile terminal apparatus is successfully authenticated. The positional information storage system also verifies whether the signature data is authentic. With this construction, it is possible to authenticate a person carrying the mobile terminal apparatus, and to verify whether data to be stored in the memory has been tampered with.
