WPA Tanthauzo ndi Kufotokozera
WPA imayimira Wi-Fi Protected Access, ndipo ndi tekinoloje yotetezera ma Wi-Fi . Zinapangidwa chifukwa cha zofooka za WEP (Wired Equivalent Privacy) , choncho zimapangitsa kuti zitsimikizidwe za WEP komanso zolembera.
WPA2 ndi mawonekedwe a WPA; Chida chilichonse chotsimikiziridwa cha Wi-Fi chagwiritsidwa ntchito ndi WPA2 kuyambira 2006.
Tip: Onani Kodi WEP, WPA, ndi WPA2 Ndi Chiyani? Ndi Yabwino Kwambiri? kuti mudziwe zambiri za momwe WPA ikuyerekeza ndi WPA2 ndi WEP.
Zindikirani: WPA ndichidule cha Windows Performance Analyzer, koma ilibe kanthu ndi chitetezo cha waya.
Zolemba za WPA
WPA imapereka mauthenga amphamvu kuposa WEP kupyolera mwa kugwiritsa ntchito njira zamakono zamakono: Chitukuko Chofunika Kwambiri Pulogalamu (TKIP) ndi Advanced Encryption Standard (AES) . WPA imaphatikizaponso kuthandizidwa kwothandizira kuti WEP sipereke.
Zotsatira zina za WPA zimalola makasitomala a WEP kugwirizanitsa ndi intaneti, komabe chitetezo chachepetsedwa kukhala makanema a WEP pa zipangizo zonse zogwiritsidwa ntchito.
WPA ikuphatikizapo chithandizo cha kutsimikiziridwa kumatchedwa otchedwa Authentic Authentication In-Service User Service, kapena ma seva a RADUIS. Ndi seva iyi yomwe ili ndi zidziwitso zowonjezera kuti ogwiritsa ntchito athe kutsimikiziridwa asanatumikire ku intaneti, ndipo izi zikhoza kukhazikitsa mauthenga a EAP (Extensible Authentication Protocol).
Kamodzi kachipangizo kamagwirizanitsa bwino ndi intaneti ya WPA, makiyi amapangidwa kudzera kumagwirana kwa njira zinayi zomwe zimachitika ndi malo ogwiritsira ntchito (kawirikawiri router ) ndi chipangizo.
Pamene kufotokoza kwa TKIP kumagwiritsidwa ntchito, uthenga wodalitsika wa uthenga (MIC) umaphatikizidwa kuti uonetsetse kuti detayo isasokonezedwe. Amalowetsa WEP yofooka phukusi lothandizira lotchedwa cyclic redundancy check (CRC).
Kodi WPA-PSK ndi chiyani?
Kusiyana kwa WPA, komwe kumagwiritsidwa ntchito pa intaneti, kumatchedwa WPA Pre Shared Key, kapena WPA-PSK. Ndi mawonekedwe ophweka koma amphamvube a WPA.
Ndi WPA-PSK, komanso yofanana ndi WEP, chifungulo cha static kapena passphrase yakhazikitsidwa, koma imagwiritsa ntchito TKIP. WPA-PSK imasintha makiyiwo pa nthawi yoikidwiratu kuti zikhale zovuta kwambiri kwa osokoneza kuti azizipeza ndi kuzigwiritsa ntchito.
Kugwira Ntchito ndi WPA
Zosankha zogwiritsira ntchito WPA zimawonekera pamene zikugwirizanitsa ndi makina opanda waya komanso poika makina ena kuti agwirizane nawo.
WPA inalinganizidwa kuti ithandizidwe pa zipangizo zisanachitike za WPA monga zomwe zikugwiritsa ntchito WEP, koma ena amangogwira ntchito ndi WPA pambuyo pa kusintha kwa firmware ndipo ena sagwirizana.
Onani momwe mungathetsere WPA pa intaneti yopanda mauthenga komanso momwe mungakonzekere WPA Support ku Microsoft Windows ngati mukufuna thandizo.
WPA zogwiritsidwa kale zifungulo zimakhalabe zovuta kuti ziwonongeke ngakhale kuti protocolyi ndi yotetezeka kwambiri kuposa WEP. Ndikofunika, kotero, kuonetsetsa kuti passphrase ili ndi mphamvu zowononga kuzunzidwa koopsa.
Onani Mmene Mungapangire Pulogalamu Yamphamvu Kuti Mupeze Malangizo, ndipo yesetsani malemba oposa 20 pa neno la WPA.
