I-WPA Inkcazo Nenkcazo
I-WPA imele ufikeleleke kwi-Wi-Fi Protected Access, kwaye iteknoloji yokhuseleko kwiinkonzo ze-Wi-Fi . Yaphuhliswa ekuphenduleni ubuthathaka be- WEP (Wired Equivalent Privacy) , ngoko ke iphucula ukuqinisekiswa kweWEP kunye neenkcukacha zokubhala.
I-WPA2 yindlela ephuculweyo yeWPA; yonke imveliso eqinisekisiweyo ye-Wi-Fi iye yasebenzisa i-WPA2 ukususela ngo-2006.
Icebiso: Bona Yintoni i-WEP, i-WPA, ne-WPA2? Yiyiphi Impumelelo? ngolwazi olungakumbi malunga nendlela iWPA efanisa ngayo neWPA2 kunye neWEP.
Qaphela: i- WPA isisigxina se-Windows Performance Analyzer, kodwa ayinanto yokwenza ukhuseleko olungenazintambo.
Iimpawu zeWPA
I-WPA inikeza ukubethelela okunamandla ngakumbi kune-WEP ngokusebenzisa ukusetyenziswa kwezinto ezimbini zobuchwepheshe obuqhelekileyo : iProjekti yeCandelo leNgcaciso yeNkcazo (TKIP) kunye ne- Advanced Encryption Standard (AES) . I-WPA iquka ukuxhaswa kwenkxaso yokuqinisekisa eyi-WEP engayinikezeli.
Okunye ukuphunyezwa kwe-WPA kuvumela ukuba abathengi be-WEP badibanise kwinethiwekhi, kodwa ukhuseleko luyancitshiswa kumazinga e-WEP kuwo onke amadivayisi axhunyiwe.
I-WPA ibandakanya inkxaso yokuqinisekiswa isebenza ngokuba yi-Remote Authentication Dial-In Serving Service servers, okanye iiseva ze-RADUIS. Yile ncedisi ekwazi ukufikelela kwiinkcukacha zekhompyutha ukwenzela ukuba abasebenzisi banokuqinisekiswa ngaphambi kokuba badibanise kwinethwekhi, kwaye leyo ingabamba kwakhona i-EAP (Imigaqo yokuQinisekisa yokuQinisekisa).
Emva kokuba ifowuni idibanisa ngempumelelo kwinethiwekhi yeWPA, izitshixo ziveliswe ngendlela yokubambisana ngezandla ezine ezenzekayo kunye neendawo zokufikelela (ngokuqhelekileyo i- router ) kunye necebo.
Xa i-encryption ye-TKIP isetyenzisiweyo, ikhowudi ye-intanethi ye-Integrity (MIC) ifakiwe ukuqinisekisa ukuba idatha ayinakukhutshwa. Itshintsha indawo ye-WEP eyimfuneko yokuqinisekisa ipakethi ebizwa ngokuba yi-cyclic redundancy check (CRC).
Yintoni iWPA-PSK?
Uhlobo lweWPA, olwenzelwe ukusetyenziswa kumanethiwekhi asekhaya, lubizwa ngokuba yi-WPA Pre Shared Key, okanye i-WPA-PSK. Yindlela elula kodwa enamandla yeWPA.
Nge-WPA-PSK, kwaye ifana ne-WEP, iqhosha le-static okanye idrafrase isetyenziswe, kodwa isebenzisa i-TKIP. I-WPA-PSK iyitshintsha ngokuzenzekelayo izitshixo kwisithuba sexesha elidlulileyo ukwenzela ukuba kube nzima ngabacuki ukuba bafumane kwaye baxhaphaze.
Ukusebenzisana neWPA
Izinketho zokusebenzisa i-WPA ziyabonakala xa zixhuma kwinethiwekhi engenazintambo kunye nokusetha inethiwekhi kwabanye ukuxhuma.
I-WPA yenzelwe ukuxhaswa kwiinkqubo zangaphambili ze-WPA njengabo basebenzisa i-WEP, kodwa abanye basebenze kuphela ne-WPA emva kokuphuculwa kwe- firmware kunye nabanye abahambelaniyo.
Jonga indlela yokukhusela i-WPA kwiNethiwekhi engenantambo kunye neendlela zokuqwalasela iNkxaso yeWPA kwi-Microsoft Windows ukuba ufuna uncedo.
I-WPA yangaphambili yabelana ngezihluthu zisasengozini ekuhlaselweni nangona iprotocol ikhuselekile ngakumbi kuneWEP. Kubalulekile ke ngoko ukuqinisekisa ukuba i-passrax isomelele ngokwaneleyo ukukhusela ukuhlaselwa ngamandla.
Jonga indlela yokwenza iphasiwedi eqinileyo ngamanye amathiphu, kwaye ujonge amanqaku angaphezu kwe-20 kwiphasiwedi yeWPA.
