When a common key is updated to a new common key, it is possible to prevent the generation of a period during which not all the general communication apparatuses are enabled to make mutual communications using encrypted data while at the same time reducing the memory consumption of the general communication apparatus. A common key control apparatustransmits a first status transition request Rto all the general communication apparatuses when all the general communication apparatusesmade a transition to a distribution completed status, and transmits a second status transition request Rto all the general communication apparatuses when all the general communication apparatusesmade a transition to an in-transit status. The general communication apparatusmakes a transition from the update completed status to the distribution completed status upon receipt of a new common key from the common key control apparatus, while it makes a transition from the distribution completed status to the in-transit status upon receipt of the first status transition request and it restores the state to the update completed status from the in-transit status upon receipt of the second status transition request.

Communication system, common key control apparatus, and general communication apparatus

An Internet terminal comprising: a communication unit that sends a local packet generated by a packet generation unit and receives a response local packet from a server apparatus; an encryption processing unit that encrypts the local packet to be sent out and decrypts the received response local packet; the packet generation unit that generates the local packet; a polling information storage unit that holds a terminal ID and a password used for identifying the internet terminal; a polling interval adjustment unit that identifies a polling interval at which the local packet is periodically sent to the router; and a control unit that sends control information to a terminal apparatus to be controlled and controls such terminal apparatus accordingly.

Home terminal apparatus and communication system

A communication system is constructed in such a manner that a user is allowed to designate a controllerand a wireless devicesimultaneously to start authentication for connection with a wireless base stationto specify the device to be connected, and to establish connection authentication without a password for the first time. Thereafter, the controllerdistributes a password to the wireless base stationand to the wireless deviceto cancel the connection authentication. Next, connection authentication with the distributed password is established. Thus, the communication system makes it possible to substantially automatically establish connection authentication, thereby eliminating a cumbersome operation by the user in implementing the connection authentication process.

One routing device which connects plural networks on which a plurality of other routing devices, including a parent router, are connected. The parent router manages network identification data to identify the plural networks. Master router data is included for each corresponding other routing device. Master router data includes master router identification data identifying whether the corresponding other routing device is a 'master router' located on a path to the parent router or a 'slave router' which is a routing device other than the master router, and includes network identification data identifying a network to which the corresponding other routing device connects. Upon startup of the one routing device, the master router data is acquired from the other routing devices on the networks to which the one routing device connects. It is determined whether a router function of the one routing device is enabled based on the acquired master router data.

A communication system in which both a communication device that does not operate intermittently and a communication device that operates intermittently are present. A communication device includes a transmission processing portion transmitting data, a timer portion counting a continuous operation request effective time during which transmitted data is always received, a transmission control portion controlling the transmission processing portion to transmit data including a continuous operation request flag causing the timer portion in a communication device that operates intermittently to start counting the continuous operation request effective time while starting its timer portion counting the continuous operation request effective time, a reception processing portion, and a reception control portion controlling the reception processing portion. Upon receiving the data wherein the flag is set, the reception control portion controls its timer portion to start counting the continuous operation request effective time.

In a control network system of household electric appliances, particularly, an each introduction of a household electric appliance thereto does not cause a change in the means of acquiring operation data by a controller, and the electric power consumption of a controller is made less. A home network system is simplified and made efficient. As a means for the above, an accessible device in a common manner to household electric appliances is incorporated into a controller by object processing using communications middlewares, and a device for linked operations is incorporated into household electric appliances. Then, it is noted that each household electric appliance needs a specific kind of another appliance and operation data thereof.

A controller () holds appliance data acquired from an appliance () regularly and without loss. A display terminal () is capable of moving to other rooms through a receptacle and holds the appliance data acquired from the appliance (). When there is loss in the appliance data for a part of time period because of a move and the like, the display terminal () executes acquisition request to the controller () to acquire this non-collected data of the appliance. The controller () transmits the appliance data to the display terminal () in response to the request of the display terminal (). The display terminal () acquires (or complements) the non-collected data from the controller () and display the data.
