| 20090204809 | INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND COMPUTER-READABLE RECORDING MEDIUM - An information processing device is arranged to acquire a first public key certificate and a first secret key from a server device by acquiring an individual identification information which is uniquely discriminable for the information processing device from the information processing device and transmitting the individual identification information to the server device. The information processing device is arranged to determine whether the information processing device is permitted to transmit device information to the server device through an encryption communication using the first public key certificate and the first secret key, by acquiring the individual identification information from the information processing device and comparing the acquired individual identification information with the individual identification information associated with at least one of the first public key certificate and the first secret key. | 08-13-2009 |
| 20090217040 | INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND COMPUTER READABLE RECORDING MEDIUM - An information processing apparatus for collecting apparatus data from an apparatus connected through a network and sending the apparatus data to a server connected through the network includes a recording unit storing a secret key and a public key certificate which are encrypted by key data and commonly distributed; an obtaining unit for obtaining, from the information processing apparatus, individual identification data by which the information processing apparatus can be uniquely identified, sending a request to provide the predetermined key data through the network to the server by specifying the individual identification data, and receiving the key data encrypted by the individual identification data from the server; and a decoder for obtaining the individual identification data from the information processing apparatus, decoding the key data by using the individual identification data, and decoding the common public key certificate and the secret key by using the decoded key data. | 08-27-2009 |
| 20090265545 | ELECTRONIC CERTIFICATE ISSUE SYSTEM AND METHOD - A registration part receives a product key of a program for performing a communication using a private key and a public key, and discrimination information of a computer using the program. The registration part registers in a management part, when an authentication of a license corresponding to the product key is completed in success, correspondence information between the product key and the discrimination information and other discrimination information regarding the correspondence information. A discrimination information sending part returns the other discrimination information to an electronic certificate issue apparatus. A checking part receives the other discrimination information and check whether the other discrimination information is registered in the management part. A certificate producing part produces, when the other discrimination information is registered in the management part, an individual certificate package containing the private key and the public key for each piece of the other discrimination information. | 10-22-2009 |
| 20090265546 | INFORMATION PROCESSING DEVICE, ELECTRONIC CERTIFICATE ISSUING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM - An information processing device acquires first identification information of a computer to which the device is coupled, and records correspondence information indicating a correspondence between a product key of a predetermined program and the first identification information, and second identification information with respect to the correspondence information, in the device, if a license authentication with respect to the product key based on the first identification information is successful. The device generates an individual certificate package including a unique secret key and public key for each second identification information, and records the individual certificate package in the device in correspondence with each second identification information. | 10-22-2009 |
| 20100180140 | DATA PROCESSING SYSTEM AND IMAGE PROCESSING SYSTEM - A data processor comprising: a bus control circuit adapted to be interfaced with a synchronous DRAM which can be accessed in synchronism with a clock signal; a plurality of data processing modules coupled to said bus control circuit for producing data and addresses for accessing a memory; and a clock driver for feeding intrinsic operation clocks to said data processing modules and for feeding the clock signal for accessing said memory in synchronism with the operations of said data processing modules to be operated by the operation clock signals, to the outside. | 07-15-2010 |
| 20100235640 | INFORMATION PROCESSING APPARATUS, METHOD OF MUTUAL AUTHENTICATION, MUTUAL AUTHENTICATION PROGRAM, AND STORAGE MEDIUM - An information processing apparatus and a counterpart apparatus supporting data communications are devised. The information processing apparatus is connected to the counterpart apparatus via a communication network. The information processing apparatus and the counterpart apparatus supporting data communications use mutual authentication using a certificate file. The information processing apparatus includes a certificate management unit, a verification information obtaining unit, and a security key generation unit. The certificate management unit encrypts and decrypts the certificate file using a security key. The verification information obtaining unit obtains verification information of the information processing apparatus. The verification information enables identification of the information processing apparatus as a unique physical entity. The security key generation unit generates the security key by conducting a non-reversible transformation of the verification information obtained by the verification information obtaining unit. The verification information is used as source data. | 09-16-2010 |
