    摘要: An unauthorized apparatus detection device, playback device, unauthorized apparatus detection system, information collection device, unauthorized apparatus detection method, a program, recording medium, apparatus information update method, and integrated circuit can detect clones of a playback device. In a management server 2, a reception processing unit 241 acquires a user terminal identifier and a first random number from a user terminal targeted for unauthorized apparatus detection, judges whether a second management server random number, which is stored in a storage unit 23 in correspondence with the user terminal identifier, matches the first user terminal random number. If the two fail to match, a display unit 22 displays a message indicating that a clone exists. If the two match, a terminal information generation unit 243 generates a new random number, and writes the generated random number as the second random number in the storage unit 23. A transmission processing unit 246 transmits the generated random number to the user terminal via a transmission/reception unit 246 and the user terminal updates the first user terminal random number to the generated random number.

    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.

    摘要: An RSA decryption apparatus that is used in an IC card or the like counters a differential fault attack. The RSA decryption apparatus computes at high speed a public key used in data verification, without having to obtain the public key from an external source. The RSA decryption apparatus includes a remainder computation unit 412 that calculates dp=d mod (p−1), and an inverse computation unit 414 that finds an inverse of dp over a residue field with p−1 as a modulus. The RSA decryption apparatus verifies a decipher text with use of the inverse of dp as the public key. The reduced bit count in inverse computation compared to if the inverse of d is found as the public key increases computing speed.

    摘要: To aim to provide a monitoring system and a program execution apparatus that are capable of maintaining the security intensity even in the case where an unauthentic install module is invalidated. Install modules included in an apparatus each monitor an install module, which is a monitoring target indicated by a monitoring pattern included therein, as to whether the install module performs malicious operations. An install module that performs malicious operations is invalidated in accordance with an instruction from an update server. The monitoring patterns are restructured by the update server such that the install modules except the invalidated install module are each monitored by at least another one of the install modules. The restructured monitoring patterns are distributed to the install modules except the invalidated install module.
