  • Patent number: 7796762
    Abstract: 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 apparatus 11 transmits a first status transition request R1 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to a distribution completed status, and transmits a second status transition request R2 to all the general communication apparatuses when all the general communication apparatuses 12 made a transition to an in-transit status.

  • Patent number: 7707418
    Abstract: A communication system is constructed in such a manner that a user is allowed to designate a controller 1 and a wireless device 3 simultaneously to start authentication for connection with a wireless base station 2 to specify the device to be connected, and to establish connection authentication without a password for the first time. Thereafter, the controller 1 distributes a password to the wireless base station 2 and to the wireless device 3 to 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.

  • Patent number: 7707306
    Abstract: 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.

  • Publication number: 20070147419
    Abstract: The present invention provides a communication network system in which communication can be securely performed via a global network from an existing terminal apparatus to an existing device connected to a local network without needing a special gateway function in a router and without performing a special setting in the router. In the communication network system (10), a communication relay client (202) performs polling on a management center network (1) via a NAT router (204); a communication relay server (102) converts a packet transmitted from a management terminal (101); and the communication relay client (202) receives the converted packet as a response to the polling via the NAT router (204) from the side of the management center network (1). The communication relay client (202) converts the converted packet to the original packet, and transmits the original packet to a device to be managed (201).

  • Patent number: 6980079
    Abstract: 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.
