Ubunikazi bokulingana obunamanethiwekhi yi- protocol yenethiwekhi evamile efaka ukuphepha ku- Wi-Fi nakwamanye amanethiwekhi angenantambo angu- 802.11 . I-WEP yenzelwe ukunikeza ama-wireless amanethiwekhi izinga elilinganayo lokuvikelwa kwangasese njengenethiwekhi ehambelana ne-wired, kodwa amaphutha wezobuchwepheshe anciphisa kakhulu ukuwusizo kwawo.
Indlela iWEP isebenza ngayo
I-WEP isebenzisa uhlelo lokubethelwa kwedatha olusebenzisa inhlanganisela yamanani angukhiye abasebenzisi nabasebenzisi. Ukuqaliswa kokuqala kwe-WEP okusekelwe ukukhiya okubhaliwe okungama- bits angu-40 kanye nama- bits angaphezulu angu-24 e-data eyenziwe ohlelweni, eholele kumakhi angu-64 bits ubude obuphelele. Ukwandisa ukuvikelwa, lezi zindlela zokubethela zakhuliswa ngokuhamba kwesikhathi ukuze zisekele izinkinobho ezinde ezihlanganisa 104-bit (idatha engu-128 bits yenombolo), ama-128-bit (152 bits total) kanye no-232-bit (256 bits total) ukuhluka.
Uma ithunyelwe ngokuxhumeka kwe-Wi-Fi , i-WEP ibhala ngokusakazwa kwedatha ngokusebenzisa lezi zihluthulelo ukuze ingasakwazi ukufundwa komuntu kodwa ingacubungulwa ngokuthola amadivaysi. Izakhi ngokwabo azithunyelwanga ngenethiwekhi kepha zigcinwe ku- adaptha yenethiwekhi engenantambo noma ku-Registry Windows.
I-WEP ne-Home Networking
Abathengi abazithengile ama-802.11b / g amasha ekuqaleni kwawo-2000 babengenayo okukhethwa kukho kokuphepha kwe-Wi-Fi etholakalayo ngaphandle kwe-WEP. Yenza inhloso eyisisekelo yokuvikela inethiwekhi yomuntu ekhaya ukuba ingene ngamakhelwane ngengozi.
Ama- router asekhaya asekela ekhaya asekela i-WEP evumela ukuba abaphathi bakwazi ukungena ezikhathini ezine ezihlukile ze-WEP ku-console ye-router ukuze i-router ingamukele ukwamukela kusuka kumakhasimende asethwe nanoma iyiphi yalezi zihluthulelo. Ngenkathi lesi sici singathuthukisi ukuphepha kwanoma yiluphi uxhumano, lunikeza abalawuli ngezinga elengeziwe lokuguquguquka kokusabalalisa izinkinobho kumadivayisi weklayenti. Isibonelo, umninikhaya angase akhethe ukhiye owodwa ongasetshenziswa kuphela ngamalungu omndeni kanye nabanye izivakashi. Ngalesi sici, bangakhetha ukushintsha noma ukususa okhiye besivakashi noma nini lapho befisa ngaphandle kokushintsha amadivaysi abo omndeni.
Kungani i-WEP ingavunyelwe ukusetshenziswa okujwayelekile
I-WEP yasungulwa ngo-1999. Phakathi neminyaka embalwa, abacwaningi abaningana bezokuphepha bathola amaphutha emklamo wayo. I "izingxenye ezingu-24 ezengeziwe zedatha eyenziwe ngesistimu" okukhulunywe ngenhla iyaziwa ngokuthi i-Initialization Vector futhi yazibonakalisa iyiphutha elibaluleke kunazo zonke leprotocol. Ngamathuluzi alula futhi atholakalayo kalula, i-hacker inganquma ukhiye we-WEP futhi uyisebenzise ukuze ingene kwinethiwekhi ye-Wi-Fi esebenzayo ngaphakathi kwendaba yamaminithi.
Izithuthukisi eziqondene nomthengisi ku-WEP njenge-WEP + ne-Dynamic WEP zisetshenziswe emizamweni yokwenza ezinye zezinkinga ze-WEP, kodwa lobu buchwepheshe abukwazi nanamuhla.
Ukushintshwa kwe-WEP
I-WEP ishintshwe ngokusemthethweni yi- WPA ngo-2004, okwathi ngokuhamba kwesikhathi yaxoshwa yi- WPA2 . Ngenkathi isebenza inethiwekhi nge-WEP inikwe amandla ngokungcono kunokuba isebenze kungekho ukuvikelwa kokungena nge-wire nhlobo, umehluko awunaki embonweni wokuphepha.
