According to an embodiment, an information processing device that includes a first storage unit and a second storage unit having power consumption different from that of the first storage unit. The information processing device also includes a control unit configured to make a control to determine a priority of information that is to be stored in the first storage unit or the second storage unit. The control unit is configured to store the information into the first storage unit or into the second storage unit based on the determined priority.

An authentication apparatus includes a first storage unit that stores proxy information containing a proxy ID and capability data, an acquiring unit that acquires the proxy information from the first storage unit, a first transmitting unit that transmits a second message containing the acquired proxy information to a terminal, a receiving unit that receives a third message and authentication data, the third message containing a first proxy ID and setting data from the terminal, and an authentication unit that performs an authentication process based on the authentication data, and a second transmitting unit that transmits the setting data to a server to which a proxy of the first proxy ID relays data communication.
摘要:
A communication apparatus which is connected to networks including first network of first security level which is lowest security level and second network of second security level, and is wirelessly connected to terminal receiving terminal identifier and password which designates one of networks, from terminal, selecting one of first security level and second security level based on an authentication result of terminal, terminal identifier, and password, forwarding, when second security level is selected, data item which is transmitted from terminal and is encrypted using cryptographic algorithm and cryptographic key to second network, and forwarding, to terminal, data item which is transmitted from second network and addressed to terminal, and forwarding, when first security level is selected, data item transmitted from terminal to first network, and forwarding, to terminal, data item which is transmitted from first network and addressed to terminal.

A presence table stores therein presence information. A storage unit stores therein in associated manner a terminal identifier unique each of a plurality of terminals and an encryption key to be used for multicast communication within a multicast group. A receiving unit receives a subscription request message from a first terminal from among the terminals. The subscription message includes the terminal identifier of the first terminal, and a request requesting subscription to the presence information present in the storage unit. An acquiring unit acquires the encryption key from the storage unit by using the terminal identifier of the first terminal. A transmitting unit transmits acquired encryption key to the first terminal.
摘要:
An authenticating unit authenticates an external terminal and stores the result of authentication in an authentication state table. A receiving unit receives a first message containing information relating to a first application and identification information unique to the external terminal. A determining unit determines whether the external terminal contained in the first message is authentic by referring to the information in the authentication state table, each time the first message is received. A generating unit generates a second message containing a port, which is to be used by the first application, and an address of the external terminal when the external terminal is determined to be authentic. A transmitting unit transmits the second message to a firewall.
摘要:
A storage unit of a relaying apparatus stores first identification information that identifies an SIP terminal and second identification that identifies other SIP terminal which is forecast as a transfer destination of a message. A transmitting-and-receiving unit receives from the SIP terminal a request message that is received before a transfer message to be transferred to other SIP terminal and that includes a processing request concerning communications and the first identification information. An obtaining unit obtains from a storage unit the second identification information corresponding to the first identification information included in the received request message. A connection establishing unit establishes communications between the other SIP terminal of the obtained second identification information and the relaying apparatus.
摘要:
A switching apparatus includes an authentication client unit that requests user authentication to a user authentication server that performs user authentication of the switching apparatus, and, when the requested user authentication is successfully performed, receives from the user authentication server, information of success of the user authentication and setting information used when terminal authentication of a terminal to be connected to the switching apparatus is relayed to a terminal authentication server that performs terminal authentication; an authentication setting unit that sets the setting information to an authentication relay unit that relays terminal authentication; and a control unit that allows the authentication relay unit to relay the terminal authentication when the setting information is set to the authentication relay unit.
摘要:
In one embodiment, there is provided a communication device including: a storage configured to store transmission packets and expected reply results; a controller configured to transmit the transmission packets to a network and to detect reply results corresponding to the transmission packets from the network; and a determination module configured to determine whether or not each of the reply results matches a corresponding one of the expected reply results. When the determination module determines that a reply result corresponding to one of the transmission packets matches a corresponding expected reply result, the controller continues to transmit another one of the transmission packets to the network and to detect a reply result corresponding to said another one of the transmission packets. When the determination module determines that the reply result does not match the corresponding expected reply result, the controller stops transmitting the remaining transmission packets to the network.
