  • Patent number: 8572386
    Abstract: 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).

  • Patent number: 8555049
    Abstract: A terminal that performs secure boot processing when booting, thereby booting reliably even if, during updating of a software module, the power is cut off or the update is otherwise interrupted. The terminal comprises a CPU, a software module storage unit, a certificate storage unit, an updating unit for updating the software module and certificate, a security device provided with a configuration information storage unit for storing the configuration information of the software module, an alternate configuration information storage unit for storing the configuration information of a software module in the configuration before the update, and a boot control unit for verifying and executing the software module by using the certificate. The terminal verifies the certificate of the software module by comparing the configuration information stored by the configuration information storage unit with the configuration information stored by the alternate configuration information storage unit.

  • Patent number: 8479000
    Abstract: 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.

  • Patent number: 8223972
    Abstract: In the key management software having a key database with a tree structure, a high-speed data encryption/decryption process is achieved by changing the tree structure without reducing the security strength when deleting or adding a key from/to the tree structure. The key management software having the key database with the tree structure, when deleting or adding a key from/to the tree structure, refers to the encryption strength comparison table and the process time comparison table to change the tree structure without reducing the security strength. This reduces the number of times an encrypted key is loaded onto the encryption/decryption processing device during the data encryption/decryption process, thus achieving a high-speed data encryption/decryption.
