20120242451 | GENERATOR SYSTEM MONITORING APPARATUS AND COMPUTER READABLE MEDIUM - There is provided a generator system monitoring apparatus for a generator system including a generator, a first measuring apparatus and a second measuring apparatus. A power-generation state determining unit determines whether the generator is generating the electric power or not. A measurement information acquiring unit acquires, when it is determined the generator is not generating the electric power, a first measurement value and a second measurement value from the generator system, the first measuring apparatus measuring electric power generated by the generator to obtain the first measurement value, and the second measuring apparatus measuring the electric power generated by the generator to obtain the second measurement value. A system state determining unit determines whether the first measuring apparatus has an abnormality or not by comparing the first measurement value and the second measurement value with each other. | 09-27-2012 |
20130067214 | COMMUNICATION DEVICE AND COMMUNICATION METHOD - There is provided a communication device in which a network access authenticating unit executes a network access authentication process with an authentication server to establish a connection to a network, the authentication process including generation of information shared with the authentication server, a communication unit receives an authentication result message from the authentication server when succeeding in the network access authentication process, the authentication result message containing an authentication result indicating success in the network access authentication process and an encrypted network key; a key transport key generating unit generates a key transport key by use of the information generated in the network access authentication process; and a network key acquiring unit acquires a network key by decrypting the encrypted network key contained in the authentication result message with the key transport key, the communication unit encrypts data with the network key and transmits encrypted data to the network. | 03-14-2013 |
20130227157 | TERMINAL APPARATUS, OPERATION METHOD OF TERMINAL APPARATUS, AND PROGRAM PRODUCT - According to one embodiment, a terminal apparatus includes a first processing unit, second processing unit, and determiner. The first processing unit is configured to execute message processing as an authentication client for network access authentication. The second processing unit is configured to execute message processing as an authentication relay between a network access authentication server and an authentication client in another terminal apparatus. The determiner is configured to choose one of the first processing unit and the second processing unit on how to process a message which is sent by the network access authentication server or the other terminal apparatus. | 08-29-2013 |
20130227173 | INFORMATION NOTIFICATION APPARATUS, METHOD, AND PROGRAM PRODUCT - According to one embodiment, an information notification apparatus includes a table and a notifier. The table is configured to store information about root nodes and information related to the nodes. The notifier is configured to generate, when a communication node is a root node, new information for that root node. The notifier is further configured to read out, when the communication node is not a root node, the information from the table. The notifier is further configured to notify the communication node of the new information or the information read out from the table. | 08-29-2013 |
20140139690 | INFORMATION PROCESSING APPARATUS, CAMERA HAVING COMMUNICATION FUNCTION, AND INFORMATION PROCESSING METHOD - An information processing apparatus has a communication part, a message receiving part, a network-information acquiring part, a peripheral-apparatus information managing part, a task accepting part, a task allocating part, a task processing part, a process-related information generating part, and a message transmitting part configured to generate a message that includes the process-related information and transmit the message including the process-related information to the other communication apparatuses via the communication part and the network. | 05-22-2014 |
20140143537 | COMMUNICATION APPARATUS AND COMMUNICATION METHOD - In general, according to one embodiment, a communication apparatus includes an obtaining unit, generation unit, and communication unit. The obtaining unit obtains a master key from a first communication apparatus. The generation unit generates an individual key using the master key. The communication unit communicates with a second communication apparatus using the individual key. | 05-22-2014 |
20140157373 | AUTHENTICATION APPARATUS AND METHOD THEREOF, AND COMPUTER PROGRAM - According to one embodiment, there is provided an authentication apparatus, including: a communication unit, a verifier and a connection configuration checker. The communication unit receives a message related to network access authentication on a first communication apparatus, the message including an address of the first communication apparatus and more than zero address of an authentication relay. The verifier verifies an authenticity of the first communication apparatus in response to receipt of the message by the communication unit. The connection configuration checker identifies a first destination to which the first communication apparatus intends to connect, on the basis of the address of the first communication apparatus or the address of the authentication relay included in the message when verification succeeds, and determines whether to authorize connection by the first communication apparatus to the first destination or not. | 06-05-2014 |
20140157386 | COMMUNICATION DEVICE, COMMUNICATION METHOD AND COMPUTER PROGRAM - According to one embodiment, there is provided a communication device including a first communication layer receiving processor to perform a receiving process on a first communication layer on data received from a first communication device. The first communication layer receiving processor includes a first key identifying unit to identify, a key required to process the data; a first attribute identifying unit to identify, pursuant to key data, first attribute information that is attribute information associated with the key as identified; and a data processor to process the data using the key as identified. The data processed by the data processor and the first attribute information are passed to a second communication layer processor configured to perform a process on a second communication layer. | 06-05-2014 |
