Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] (system structure)

[0020] figure 1 is a block diagram showing the structure of the access point system 10 related to the embodiment of the present invention. The system 10 is equivalent to a base station that relays data communication of a wireless LAN or a wired LAN. In other words, the system 10 is equivalent to a network connection device with a relay function, and is used for data communication relay between a radio terminal with a radio communication function and a network (especially a wireless local area network, a wired local area network or the Internet).

[0021] exist figure 1 Among them, the central processing unit 11 executes the program loaded in the memory 13, and realizes the relay function of the wireless local area network or the wired local area network. Specifically, the central processing unit 11 controls a wireless LAN controller...

Abstract

The invention relates to an access point having a function of checking application / non-application of an encryption function in each of radio communication packets, and determining a communication service for a packet on the basis of the application / non-application. The access point has a radio LAN packet process section having a function of checking application / non-application of WEP to a packet received from a radio terminal.

Description

technical field [0001] The present invention generally relates to an electronic device with a relay function, which is used for the relay between a wireless terminal device and a network, and particularly relates to an access point technology with a function of monitoring the security status of a wireless communication packet. Background technique [0002] Over the years, the construction of wireless networks mainly based on the IEEE802.11 wireless local area network standard has achieved great development. A wireless network includes a plurality of radio terminals and network connection devices called access points (hereinafter referred to as "access points" or "APs"). The radio terminal has a radio communication function. For example, the radio terminal is a personal computer, or a mobile information device (PDA) (which may be a mobile phone). The AP has a relay function and is used for relaying between a terminal device (such as a personal computer) and the main network...
