Problems solved by technology

Therefore, it is cumbersome to have to pre-store the MAC addresses of all network devices that are allowed to communicate
In addition, in the public wireless LAN, because there is a large amount of turnover (turnover) of the communication terminals served, so every time a new device is added to the public wireless LAN, the operator needs to update the registered MAC address when adding a new MAC address. The data table of the address is updated, this operation will be more troublesome
If the registration and update operations are ignored, smooth communication between devices connected to the wireless LAN is hindered

Embodiment Construction

[0024] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] [A-1. Structure of the embodiment]

[0026] FIG. 1 shows the structure of a wireless LAN 1 according to the present embodiment. The wireless LAN shown in the figure is for home use. An access point (hereinafter referred to as "AP") 10 and network-connected devices ("network-connected devices" means devices currently connected to the network) located within the wireless area covered by the AP 10, such as communication terminals 20a and 20b, printers 30 and scanner 40, wirelessly transmit data. The AP10 also acts as a dial-up router. AP 10, upon receiving a request to connect to the Internet from communication terminal 20b, accesses an Internet service provider through a public network, and connects communication terminal 20b to the Internet to relay communication. Communication terminals 20a and 20b are personal computers into which LAN cards a...

Abstract

The present invention provides a technique of enabling communication devices constituting a wireless network to register and update identification information easily, and thereby ensuring security of the communication devices and the wireless network and of detecting a communication device suspected of accessing a wireless network illegally and informing a user of the communication device. Communication terminal 20b detects and reports networked devices constituting wireless LAN 1, and if communication with the reported networked devices is permitted through an operation of operating unit 204, registers the MAC addresses of the networked devices in permission table 206a. Communication terminal 20b permits communication with a networked device constituting wireless LAN 1 whose MAC address has been registered in permission table 206a, and prohibits communication with a networked device constituting wireless LAN 1 whose MAC address has not been registered in permission table 206a.

Description

technical field [0001] The present invention relates to techniques for securing communication devices and wireless networks. Background technique [0002] In recent years, wireless LANs (Local Area Networks) have spread not only in office use but also in home use. This is due in part to the advantage of wireless LANs that devices such as computers or printers do not need to be connected by communication cables in order to operate. However, in a wireless LAN, since data is exchanged wirelessly, hackers can gain unauthorized access to the network with relative ease compared to a cable-connected LAN while remaining undetected. For example, unauthorized access to a wireless LAN may involve using a communication device that conceals its identity to break into the wireless LAN to steal data stored in the device or exchanged between devices connected to the wireless LAN, or through a compromised wireless LAN. LAN to access another communication network. [0003] To solve the abo...
