[0073] A-1. The general structure of the system:

[0074] figure 1 It is an explanatory diagram showing a schematic configuration of a network system using a wireless network relay device according to an embodiment of the present invention. The network system 1000 includes a wireless network relay device 10 as a wireless connection device and two client devices 20 and 30 . In addition, the client device is simply referred to as "client" below.

[0075] The wireless network relay device 10 in this embodiment is an access point device conforming to IEEE802.11. The wireless network relay device 10 is also referred to as "AP10" below. The AP 10 relays the wireless communications of the client devices 20 and 30 . In this embodiment, AP10 also functions as a router, and is connected to the Internet INT via a wired cable. AP10 supports AOSS (AirStation One-Touch Secure System) and WPS (Wi-Fi Protected System) known in the past as a function of automatically setting wireless co...

[0154] As above, according to the first embodiment of the simple authentication process, the AP 10 (wireless connection device) causes the PC 20 (client device) to display that a plurality of groups are assigned in a correspondence list in a one-to-one correspondence with each of a plurality of characters. An image group composed of images. In the example of the above-mentioned embodiment, three sets of display are performed using the three image selection boxes C71, C72, and C73 of the authentication screen W7. Furthermore, the AP 10 acquires designation of one image and designation of order for each image group ( C71 , C72 , C73 ). That is, since the operation of specifying the images and specifying the order of the plurality of displayed image groups is only required on the PC 20 side, the input is simple. In addition, on the PC 20 side, images are designated one by one from a plurality of image groups, so that the degree of freedom of image designation can be increased, a...

[0184] In the second embodiment of the present invention, a configuration in which filtering processing executed in wireless communication setting processing is different will be described. In addition, "filtering processing" here means that AP10 discards the source MAC address and in step S112 ( Figure 5 ) to process packets whose MAC addresses are inconsistent. Only parts having configurations and operations different from those of the first embodiment will be described below. In addition, in the drawings, the same reference numerals as those of the first embodiment described above are attached to the same structural parts as those of the first embodiment, and detailed description thereof will be omitted.

[0185] Figure 24 It is a sequence diagram showing the procedure of wireless communication setting processing in the second embodiment. In addition, in Figure 24 For the convenience of illustration, the illustration of step PH4 (acquisition of recommended files by t...

Abstract

The invention provides an authentication method and a wireless connection device. In the wireless connection device used by a client device, the client device is authenticated through a simple method by using the form of a password that is difficult to copy or that cannot be continued for use even if copied. The authentication method of an embodiment includes the following steps: (a) displaying by the wireless connection device an image group consisting of images each assigned to a respective one of a plurality of characters in advance; (b) sending a plurlaity of images selected from the displayed image group and an order of the plurality of images by the client device; (c) creating by the wireless connection device a set of characters by using the plurality of images, the order of the plurality of images and correspondence of the characters and the images that are obtained; and (d) performing authentication by the wireless connection device based on a determination of whether the created set of characters matches information of a permission candidate.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2012-118843 filed on May 24, 2012, and the entire disclosure thereof is incorporated herein by reference. technical field [0002] The invention relates to a wireless communication authentication technology. Background technique [0003] It is known that a user using a wireless network relay device generally authenticates using a password composed of a character string in order to confirm whether or not the user has the authority to use the wireless network relay device. When authentication is performed using a password, a fixed password method in which authentication is performed by inputting a predetermined user name and a corresponding password is widely used. The fixed password method is widely used because of its simplicity, but there is a possibility of password leakage. In the fixed password method, the password is in an easily duplicatable format such as a character string, and the once...
