[embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention:
Referring to Fig. 1-2, the present invention introduces a kind of electronic weighing apparatus system that can wireless authentication, it includes access controller 1 and several electronic scales 2, described each electronic scale 2 is provided with controller module 21 and the key-press module 22 that is connected on the controller module 21, display module 23, Weighing module 24, and wireless interface module 27, described wireless interface module 27 is provided with wireless encryption authentication module 271, wired connection has several WAPs 3 that electronic scale 2 wireless access are provided on the described access controller 1, described wireless interface module 27 and WAP 3 wireless connections, wired certificate server 4 and backstage server 5 of tracing to the source that is connected with also on the described access controller 1, described certificate server 4 is username and password to the different authentication information of wireless interface module 27 configurations of each electronic scale 2, electronic scale 2 sends to certificate server 4 by wireless interface module 27 and allows the externally online solicited message of connection, online solicited message and Basic Authentication information that 4 pairs of certificate servers receive compare, if consistent, then be authentication success, open access controller 1 external access port is given corresponding electronic scale 2.
Also be connected with printer module 25 and card reader module 26 on the controller module 21 of described electronic scale 2.
Referring to Fig. 3, the present invention has also introduced a kind of authentication method of electronic weighing apparatus system, and it comprises the steps:
Step 1 101, configuration electronic scale 2, controller module 21 is set in electronic scale 2 and is connected to key-press module 22, display module 23, Weighing module 24, wireless interface module 27 on the controller module 21, at wireless interface module 27 interior loading wireless encryption authentication modules 271;
Described controller module 21 uses the CPU of freescale, in the ARMLinux of controller module 21 operating system, the ltib compilation tool that use carries carries out cross compile with system file and wpa_supplicant installation file, Compilation Method is as follows: at first the compressed file wpa_supplicant.tar.gz with wpa_supplicant unzips to＜ltib home 〉/the rpm/Build/ catalogue under, order to be: cd＜ltibhome 〉
./ltib-m?prep?-p?wpa_supplicant/spec
Then compile this software package and get final product, its order is:
./ltib-m?scbuild-p?wpa_supplicant/spec
Then use the ./creatrootfs order that these are packaged into the rootfs.tar.bz2 file, then use the file after the MfgTool burn recording software will be packed to be burnt in the electronic scale by the usb data line, restart electronic scale after burning is finished and get final product.
Step 2 102 is set up traceability system, with certificate server 4, backstage trace to the source server 5, WAP 3 and access controller 1 wired connection, with wireless interface module 27 and WAP 3 wireless connections of electronic scale 2;
Before setting up traceability system, at first to dispose certificate server 4, at a computing machine that (SuSE) Linux OS is installed Freeradius software is installed, software version is freeradius-server-2.1.12.tar.gz, carry out gunzip freeradius-server-2.1.12.tar.gz and obtain gunzip freeradius-server-2.1.12.tar file, then carry out cd freeradius-server-2.1.12 after the execution decompression bag order tar – xvffreeradius-server-2.1.12.tar and enter the freeradius-server-2.1.12 file, installation is finished in execution ./configure and make install order under this document presss from both sides.Then at certificate server the MySql database is installed, is carried out the installation that MySql is finished in yum installmysql mysql-server php-mysql mysql-devel-y order.
Step 3 103 by the wireless interface module 27 configurations different authentication information of certificate server 4 to each electronic scale 2, and deposits all authentication informations in the database of certificate server 4;
Specific practice: carry out Chkconfig mysqld on and service mysqldstart order startup MySql service at certificate server 4, carry out the radius-X order and start the Radius service, the authentication information that adds electronic scale in the MySql database, i.e. username and password.Start the wpa_supplicant background service, can be undertaken by built-in command wpa_cli, the order that starts service is as follows: wpa_supplicant-Dwext-B-iwlan0-c/etc/wpa.conf.
Step 4 104, title and the encrypting and authenticating mode of configuration WAP;
Here the title of WAP uses SEU517 as example, and other titles also can be used; The encrypting and authenticating mode selects EAP-PEAP mode in the WPA-enterprise version as example here, and other modes are with reference to configuration, and specific instructions is as follows:
Wpa_cli set_network 0ssid " SEU517 " // configuration WAP name is called SEU517
Wpa_cli set_network 0 key_mgmt WPA-EAP // configuration encrypting and authenticating mode is WPA-EAP
Wpa_cli set_network 0eap PEAP // configuration authentication method is PEAP, also can be set to TLS or TTLS here.
Step 5 105, identical authentication information in database with certificate server of configuration in the controller module 21 of each electronic scale 2, the authentication information that control module disposes in all electronic scales respectively with the database of certificate server in all authentication information corresponding identical one by one;
Specific instructions is as follows:
Wpa_cli set_network 0identity " xiangshan " // user name
Wpa_cli set_network 0password " xiangshan " // password
Step 6 106, electronic scale authenticate to certificate server by wireless interface module, obtain the online license.Concrete steps are as follows:
Start electronic scale, electronic scale will send MAC (Medium/MediaAccess Control, the Chinese meaning is logic) broadcast packet initiatively seeks access point, corresponding access point can feed back to electronic scale again with the MAC Address (logical address) of oneself, and then electronic scale just can mail to the authentication information with the user name password certificate server and authenticates.
If authentification failure, electronic scale can constantly send broadcast packet until authentication success.In case authentication success, then open visit port.
Whether detected electrons weighing apparatus is provided with fixedly IP behind the authentication success.If there are " ifconfig wlan0IP address " order, then the IP address in the utility command in the end of script file; If " udhcpc-i wlan0 " order, then by the server automatic IP address allocation.
Described wireless encryption authentication mode adopts WPA enterprise version or WPA2 enterprise version.Authentication method comprises EAP-TLS, EAP-TTLS and EAP-PEAP.
The present invention adds the wireless network card with the wireless encryption authentication module in existing electronic scales embedded system, so that the food market electronic scales is through the authentication accessing Internet, strengthened the security of food market electronic scales data transmission, avoided not passing through arbitrarily present networks WAP accessing Internet by the disabled user who authenticates.
Tracing to the source in the backstage that 2 pairs of networks of electronic scale store merchandise news behind authentication success, server 5 conducts interviews and the inquiry of merchandise news and the process of renewal.
In fact server 5 has been stored the quality tracing credential information of a large amount of commodity owing to trace to the source in backstage in network, the information content can comprise: the food place of production, the condition of production, medicining condition, intermediate links situation, inspection and quarantine information etc., electronic scale 2 authentication online and by realizing the renewal of merchandise news with the trace to the source communication of server 5 of backstage, when vending articles, electronic scale 1 connects by authentication connects to the Net, timely the print quality credential information of tracing to the source.
