Fig. 2 shows a kind of flow diagrams of Wifi authentication methods provided in an embodiment of the present invention, as shown in Fig. 2, should Method includes the following steps:
201, Wifi authenticating devices and Wifi certificate servers are matched, and Wifi authenticating devices are according to Wifi authentication services The authentication information that device is sent generates Wifi certifications URL and identifying code;
202, terminal scans/reads the Quick Response Code on Wifi authenticating devices, obtains certification URL;
203, terminal completes Wifi certifications by certification URL to Wifi certificate servers;
204, the more certification URL of Wifi certificate servers are authenticated, and preserve authentication record;
205, certificate server is redirected to wireless router by terminal and is authenticated;
Wireless router (AP) is configured to not enable password, is set as WebPortal certification modes, is directed toward authentication service Device.
206, wireless router inquires the authentication record of certification URL to Wifi certificate servers, and according to authentication record Complete WebPortal certifications;
207, wireless router is to terminal return authentication result.
In a particular application, for authenticating device with after the completion of certificate server pairing, terminal is directly connected to WiFi, accesses and appoints Meaning webpage will then be automatically redirected to certificate server, and the prompt of certificate server back page can scan the two-dimensional code login, or Identifying code login can be inputted.Terminal obtains certification URL or identifying code by authenticating device,
Wherein terminal can there are three types of login modes to obtain certification URL by authenticating device.
The first is to scan the two-dimensional code login.Terminal scans/reads the Quick Response Code on authenticating device, obtains and is directed toward certification clothes The certification URL of business device, then accesses certification URL, certificate server passes through the information such as the URL sequence numbers carried and dynamic password Certification is completed using standard OTP (HOTP/TOTP) or similar verification flows.Certificate server preserves related success after certification success Information, and interacted with wireless router (AP) by WebPortal flows, AP shows successfully Portal and user is allowed to access mutually Networking or Intranet.
Second is logged in by identifying code.Logging device directly inputs dynamic password, certificate server in the prompt page All sequence number/Seed are traversed after obtaining dynamic password and are completed using standard OTP (HOTP/TOTP) or similar verification flows Certification.Certificate server preserves related successful information after certification success, and is interacted with AP by WebPortal flows, and AP is shown Success Portal simultaneously allows user to access internet or Intranet.
The third is that NFC and audio log in.Similar with Quick Response Code login, logging device can be obtained by NFC or audio The information such as the certification URL on authenticating device are taken, and complete subsequent authentication.
Using Quick Response Code to log in the terminal can use the two-dimensional code scanning software of standard to complete.NFC and audio log in It needs in addition to complete using the software specially developed, also direct Quick Response Code logs in the software specially developed, and specific software reading is recognized Can be the non-URL format such as URL format or other XML when demonstrate,proving facility information.It logs in and can wrap using the third above-mentioned mode Terminal, such as the mobile phone without camera function, notebook, PC of two-dimensional code scanning etc. can not be carried out by including.
Above method terminal such as user mobile phone/pad needs to access Wifi, first the WiFi without safety in connection, opens two Code scanning software is tieed up, the Quick Response Code in scanning certification equipment obtains certification URL, click or automatic access registrar URL, you can complete At WiFi network access authentications, and show the successful Portal pages of an acquiescence.
In another achievable mode, a kind of flow diagram of Wifi authentication methods as shown in Figure 3, such as Fig. 3 Shown, this method comprises the following steps:
301, Wifi authenticating devices and Wifi certificate servers are matched, and Wifi authenticating devices are according to Wifi authentication services The authentication information that device is sent generates Wifi certifications URL and identifying code;
302, terminal scans/reads the Quick Response Code on Wifi authenticating devices, obtains certification URL;
303, the terminal scans the Quick Response Code by the APP being arranged in the terminal and obtains Wifi certifications URL;
The terminal parses the Wifi certifications URL, by SSID connection Wifi and 802.1X certifications is enabled, to no circuit Wifi certification requests are sent by device;
304, the wireless router receives the Wifi certification requests, and completes Wifi certifications by certificate server;
Above-mentioned wireless router can pass through radius agreements with certificate server interaction.
305, the wireless router sends authentication result to the terminal.
Wireless router (AP) is configured to 802.1X patterns in the above method, and radius is directed toward certificate server.
Terminal opens APP, the certification URL by scanning the two-dimensional code, on NFC or audible acquisition authenticating device, solution Certification URL is analysed, by SSID connection WiFi and 802.1X certifications are enabled, using sequence number as 802.1X user, with dynamic password As 802.1X passwords, 802.1X certifications are completed by certificate server and AP.
If terminal device does not have camera, NFC or audio devices, user that can connect AP and using standard 802.1X clients initiate access authentication, and the sequence number shown using on authenticating device is as 802.1X user, with authenticating device The identifying code of upper display completes 8021.X certifications as 802.1X passwords.
Certificate server is verified user using standard OTP (HOTP/TOTP) or similar according to the radius agreements of standard Flow completes certification to user/password (sequence number/dynamic password), and certification URL can be other data formats such as XML.
For example, user mobile phone needs to access WiFi, first installs and enable APP, the Quick Response Code in scanning certification equipment, Certification URL is obtained, WiFi network access authentications are completed automatically by standard 802.1X.
Fig. 4 is the structural schematic diagram of Wifi Verification Systems provided in an embodiment of the present invention, as shown in figure 3, the Verification System Including:Wifi authenticating devices 41, Wifi certificate servers 42 and terminal 43 are provided with short distance nothing in the Wifi authenticating devices Line communicates NFC device;
The Wifi certificate servers send certification letter for the Wifi authenticating devices into pre-determined distance Breath;
For example, above-mentioned authentication information includes:The sequence numbers of Wifi authenticating devices, Seed, IP or DNS, current time, Verify code length, time step, SSID.
The Wifi authenticating devices, the authentication information for obtaining the transmission of Wifi certificate servers, and according to the certification Information generates Wifi certifications URL;
Since the time step in authentication information is variation, therefore the authenticating device can be according to setting, when every one section The Quick Response Code of the certification URL of interior display is continually changing.
The Wifi authenticating devices are additionally operable to generate Quick Response Code according to the Wifi certifications URL, and show the two dimension Code;
The terminal, for obtaining Wifi certification URL by scanning the Quick Response Code, and according to the Wifi certifications URL Wifi certification requests are sent to the Wifi certificate servers;
The Wifi certificate servers, for completing Wifi certifications according to the Wifi certifications URL.
The system also includes:Wireless router 44;
The terminal, for obtaining Wifi certifications URL by scanning the Quick Response Code;
The terminal, for sending Wifi certification requests to the Wifi certificate servers according to the Wifi certifications URL;
The Wifi certificate servers, the certification request sent for receiving the terminal, and according to the Wifi certifications URL completes Wifi certifications, and preserves authentication record;
