Provided is a key migration device which can securely and reliably control the migration of keys. A migration authority (101) fetches a generation level which is the security level of a first electronic terminal (3011) and an output destination level which is the security level of a third electronic terminal (3013), decides whether the relationship between the generation level and the output destination level satisfies a predetermined condition when a request for fetching a collection of keys is received from the third electronic terminal (3013), outputs the key generated by the first electronic terminal (3011) among the collection of keys to the third electronic terminal (3013) if the predetermined condition is fulfilled, and restricts output to the third electronic terminal (3013) of the key generated by the first electronic terminal (3011) among the collection of keys if the predetermined condition is not fulfilled.

The present invention provides an information processing device, an authentication system, etc. that save a server the trouble of updating a database, etc., even when a software module in a client device is updated, and that are capable of verifying whether software modules that have been started in the client device are valid. The terminal device A100 holds private keys 1 and 2, and performs authentication processing with the terminal device B101 using the private key 2. The private key 1 has been encrypted such that the private key 1 is decryptable only when secure boot is completed. The private key 2 has been encrypted such that the private key 2 is decryptable using the private key 1 only when the application module X that has been started is valid. When the authentication processing is successful, the terminal device B101 verifies that the terminal device A100 has completed secure boot and the application module X that has been started in the terminal device A100 is valid. Also, the terminal device B101 performs the authentication processing using the same private key 2, regardless of whether a program pertaining to the secure boot of the terminal device A100 is updated or not.

According to the present invention provided is an accounting means that is superior in safety and usability. The accounting means comprises: payment means including a plurality of systems of communication means; charging means including a plurality of systems of communication means; and settlement means including a plurality of systems of communication means. Since the payment means and the settlement means exchange transaction data by communicating with each other, it is possible to prevent the assessment of an illegal charge by the charging means. In addition, since a signature (a digital signature) and an accounting statement are exchanged by communication between the payment means and the charging means, the efficiency of the sale can be improved.

The present invention aims at providing an information processing terminal, a status notification system, and a status notification method that can protect both privacy and security when a status of the information processing terminal is notified to a server. An information processing terminal 10 has a disclosure/nondisclosure determination section 1001 that determines a notifiable server for each entry; a log concealing section 1002 that conceals an entry; a multi-log measurement section 1003 that commands to update hashes as to a plurality of parties; a log configuration section 1004 that configures a log directed at a notified party and that causes performance of signing action; a verification request section 1005 that requests verification; a policy storage section 1006 that stores a policy used for determining a party that can be notified; and a log storage section 1007 for storing the entry. The information processing terminal 10 commands accumulation, into a hash, of entries subjected to processing suitable for each notified party, such as concealing operation.

Provided is a data storage device capable of safely and effectively updating software of a home electric apparatus. In the home electric apparatus (100) in which currently used data is to be updated to new data, a reception unit (140) receives encrypted new data and a serial number of data to be updated. A key generation unit (112) generates a key by executing a predetermined irreversible calculation on the unique information correlated to the currently used data by a number of times based on the serial number of the data to be updated. An update unit (113) decrypts the new data by using the key.

A useful ticket management system is provided, which can perform adjustment using a ticket to which non-updatable value information is assigned together with an electronic value, according to a payment form. The ticket management system includes an IC tag attached to a money ticket, a money ticket management server, and a mobile terminal. The IC tag holds a money ticket ID for identifying the money ticket, and reads the money ticket ID. The money ticket management server includes a storage unit, receives the money ticket ID from the mobile terminal, and writes a valid money ticket ID to the storage unit. The mobile terminal includes a storage unit, acquires the money ticket ID held in the IC tag, transmits the acquired money ticket ID to the money ticket management server, and writes amount information of the money ticket identified by the valid money ticket ID to the storage unit.
摘要:
The present invention is designed to enable a secure device to authenticate a terminal application that operates on an information processing terminal and that accesses the secure device. An application issue request transmitter (301) of the information processing terminal (30) sends a request for issue of a terminal application to an application issuer (101). The application issuer (101) of an secure device (10) reads a terminal application (31) from an application storage (105) and embeds authentication information in the terminal application (31), associates an ID and the authentication information of the terminal application (31) and save them in an issue information storage (106), and sends the terminal application (31) to an application receiver (302) of the information processing terminal through an application transmitter (102). The application receiver (302) starts the terminal application (31). An application authenticator (311) of the terminal application (31) performs an authentication with the secure device (10) by means of the application authentication information.
