Ubume obunamalungelo obumbano ngumgaqo-nkqubo wenethiwekhi oqhelekileyo oongeza ukhuseleko kwi- Wi-Fi nakwezinye iinqununu ezingama-802.11 . I-WEP yenzelwe ukunika amanxibelelwano angenawonga inqanaba elilinganayo lokukhusela ngasese njengenethiwekhi ehambelana nenethiwekhi, kodwa iimpazamo zezobugcisa zinciphise kakhulu ukusetyenziswa kwazo.
Indlela iWEP isebenza ngayo
I-WEP isebenzisa iskrini sokubhaliweyo kwedatha esisebenzisa inhlanganisela yamanani akwi-key-generated-generated values. Ukuphunyezwa kwangaphambili kwee-WEP ezixhasayo zokufakela izitshixo ze-40 bits kunye neengongoma ezongezelelweyo ezingama-24 zedatha eveliswe kwinkqubo, ekhokelela kwizihluthulelo ezingama-64 ubude bomyinge. Ukwandisa ukukhuselwa, ezi ndlela zokubhalwa kwenkcazo zagqitywa kamva ukuze zixhase izixhobo ezide ziquka i-104-bit (128 bits of data total), 128-bit (152 bits total) kunye ne-232-bit (256 bits total).
Xa isebenziselwa uxhumano lwe-Wi-Fi , i-WEP ibhala umtsalane wolwazi usebenzisa ezi zitshixo ukuze kungabonakali abantu kodwa kusenokucutshungulwa ngokufumana izixhobo. Izitshixo ngokwawo azithunyelwa phezu kwenethiwekhi kodwa zigcinwa kwi- adapter yenethiwekhi ye -wireless okanye kwi-Windows Registry.
I-WEP kunye neKhaya
Abathengi abathengile ii-802.11b / g kwii-routers ekuqaleni kwe-2000 babengenayo i-Wi-Fi yokhetho lokuphepha ngaphandle kweWEP. Yayinceda injongo ebalulekileyo yokukhusela inethwekhi yomzi ukusuka ekungenwe ngengozi ngabamelwane.
I- router yasekhaya ebanzi exhasa i-WEP ivumela ukuba abalawuli bakwazi ukungena kwiimpawu ezine ezihlukeneyo ze-WEP kwi-console ye-router ukuze i-router iyakwamukela ukuxhomekeka kumakhasimende asekwe naliphi na kwezi zitshixo. Nangona le nxalenye ingaphuculanga ukhuseleko lwaluphi na uxhumano lomntu, linikeza abalawuli idijithi eyongezelelweyo yokuguquguquka kokusabalalisa izitshixo kumadivayisi athengiweyo. Ngokomzekelo, umninikhaya unokukhetha ukhiye omnye ozakusetyenziswa kuphela ngamalungu entsapho kunye nabanye kwiindwendwe. Ngalolu hlobo, banokukhetha ukutshintsha okanye ukususa izitshixo zabavakalisi nanini na bafuna ngaphandle kokuguqula iifowuni zabo.
Kutheni i-WEP ingaxhaswanga kuSebenzi jikelele
I-WEP yaqaliswa ngo-1999. Kwiminyaka embalwa, abaphandi abaninzi bezokhuseleko bafumanisa iimpazamo ekuyilo. "Iinkcukacha ezongezelelweyo ezingama-24 zedatha eveliswe kwinkqubo" ezikhankanywe ngasentla zibizwa ngokuba yi-Initialization Vector kwaye zibonakaliswe ukuba ziyiyona nto ibaluleke kakhulu. Ngezixhobo ezilula kwaye zifumaneka lula, i-hacker ingakwazi ukukhetha ukhiye we-WEP kwaye uyisebenzise ukuze ungene kwinethiwekhi esebenzayo ye-Wi-Fi ngaphakathi kwimizuzu embalwa.
Ukunyusa okuthe ngqo kumthengisi ku-WEP njenge-WEP + kunye ne-Dynamic WEP kuphunyezwe emzamweni wokubamba ezinye iingxaki ze-WEP, kodwa ezobuchwephesha nazo azinako namhlanje.
Ukutshintshwa kweWEP
I-WEP yatshintshwa ngokusemthethweni yi- WPA ngo-2004, eyayibuyiswa kwakhona yiWPA2 . Nangona isebenze inethiwekhi kunye ne-WEP inikwe amandla ngokufanelekileyo kunokuba isebenze kungekho khuselo lwe-wireless encryption kukho konke, umehluko awunyanzelwanga kwindlela yokuphepha.
