Incazelo ye-WPA nencazelo
I-WPA imele i-Wi-Fi Access Protected, futhi iyinethiwekhi yezokuphepha yamanethiwekhi e -Wi-Fi . Yenzelwe ukuphendula ubuthakathaka be- WEP (Wired Equivalent Ubumfihlo) , ngakho-ke kuthuthukisa ukuqinisekiswa kwe-WEP kanye nokufaka umbhalo wokubhala.
I-WPA2 ifomu le-WPA elithuthukisiwe; yonke imikhiqizo eqinisekisiwe ye-Wi-Fi isetshenziswe ku-WPA2 kusukela ngo-2006.
Ithiphu: Bona Yini i-WEP, i-WPA, ne-WPA2? Yikuphi Okuhle Kakhulu? ukuze uthole olunye ulwazi mayelana nokuthi i-WPA ifanani ne-WPA2 ne-WEP.
Qaphela: I- WPA iyisifinyezo se-Windows Performance Analyzer, kodwa ayihlangene nokuphepha okungenantambo.
Izici ze-WPA
I-WPA inikeza ukubethelwa okunamandla kune-WEP ngokusebenzisa ubuchwepheshe obubili obujwayelekile: I- Temporal Key Integrity Protocol (TKIP) ne- Advanced Encryption Standard (AES) . I-WPA ihlanganisa nokusekelwa okuqinisekisiwe okwakhelwe ngaphakathi ku-WEP enganikeli.
Okunye ukuqaliswa kwe-WPA kuvumela amaklayenti e-WEP ukuba axhume kwinethiwekhi futhi, kodwa ukulondeka kuncishiselwa kumazinga we-WEP kuwo wonke amadivayisi axhunyiwe.
I-WPA ihlanganisa ukwesekwa kokuqinisekiswa okukhonzayo okubizwa ngokuthi amaseva we-Remote Authentication Dial-In Service Service, noma amaseva e-RADUIS. Yile seva enokufinyelela kuziqinisekiso zedivaysi ukuze abasebenzisi bakwazi ukuqinisekiswa ngaphambi kokuba baxhume kwinethiwekhi, futhi lokho kungabamba imilayezo ye-EAP (Extensible Authentication Protocol).
Uma idivaysi ixhuma ngempumelelo kwinethiwekhi ye-WPA, okhiye bakhiqizwa ngendlela yokubambisana ngezindlela ezine ezenzeka ngephuzu lokufinyelela (ngokuvamile umzila ) kanye nedivayisi.
Uma ukubethela kwe-TKIP kusetshenziswa, ikhodi yobuqotho yomlayezo (i-MIC) ifakiwe ukuqinisekisa ukuthi idatha ayinakuliswa. Ishintsha isiqinisekiso samaphakethe esiphelele se-WEP esibizwa ngokuthi i-cyclic redundancy check (CRC).
Kuyini i-WPA-PSK?
Ukuhluka kwe-WPA, eyenzelwe ukusetshenziswa kumanethiwekhi omkhaya, kubizwa ngokuthi i-WPA Pre Shared Key, noma i-WPA-PSK. Kuyindlela elula kodwa enamandla ye-WPA.
Nge-WPA-PSK, futhi efana ne-WEP, ukhiye we-static noma i- passphrase isethwe, kodwa isebenzisa i-TKIP. I-WPA-PSK iyashintsha ngokuzenzakalelayo okhiye ngesikhathi sokusetha esethiwe ngaphambi kokuba kube nzima kakhulu kubaduni ukuthola nokuwasebenzisa.
Ukusebenza ne-WPA
Izinketho zokusebenzisa i-WPA zibonakala uma zixhuma kwinethiwekhi engenantambo kanye nalapho ihlela inethiwekhi kwabanye ukuyixhuma.
I-WPA yenzelwe ukusekelwa kumadivayisi wangaphambi kwe-WPA afana nalawa asebenzisa i-WEP, kodwa abanye basebenze kuphela nge-WPA ngemuva kokuthuthukiswa kwe- firmware kanti abanye abahambisani neze.
Bheka ukuthi ungenza kanjani i-WPA kwinethiwekhi engenantambo nokuthi ungayilungiselela kanjani ukusekela kwe-WPA ku-Microsoft Windows uma udinga usizo.
Ama-WPA okwenziwe ngaphambilini angakaboshwa ekuhlaselweni yize le protocol ivikeleke kakhulu kune-WEP. Kubalulekile ukuthi-ke, ukuqinisekisa ukuthi umbhalo wesigcawu unamandla ngokwanele ukuvimbela ukuhlasela okunamandla.
Bheka indlela yokwenza iphasiwedi eqinile ngamanye amathiphu, futhi uhlose izinhlamvu ezingaphezu kuka-20 kuphasiwedi ye-WPA.
