I-WEP imelela Ubumfihlo be-Wired Equivalent, inamba yezokuphepha yenethiwekhi ye-Wi-Fi . Ukhiye we-WEP wuhlobo lwephasiwedi yokuphepha yamadivayisi we-Wi-Fi. Izinkinobho ze-WEP zenza iqembu lamadivayisi kunethiwekhi yendawo ukuthi lishintshane ngemfihlo (imathematikhi encoded) imilayezo komunye nomunye ngenkathi kufihla okuqukethwe kwemiyalezo ekubukeni kalula ngabangaphandle.
Indlela Amakhi E-WEP Asebenza Ngayo
Abaphathi benethiwekhi bakhetha ukuthi yiziphi izinkinobho ze-WEP ezizozisebenzisa kumanethiwekhi abo .Njengoba yingxenye yenqubo yokuvumela ukuvikeleka kwe-WEP, okhiye abalinganayo kumele kubekwe kuma- router kanye nedivayisi ngayinye iklayenti ukuze bonke baxhumane nomunye uxhumano lwe-Wi-Fi.
Izihluthulelo ze-WEP zihambisana namanani we- hexadecimal athathwa ezinombolo 0-9 nezinhlamvu ze-AF. Ezinye izibonelo zezinkinobho ze-WEP ziyi:
- I-1A648C9FE2
- 99D767BAC38EA23B0C0176D152
Ubude obudingekayo bekhiye le-WEP buxhomeke kunoma yiliphi izinga lezinga le-WEP inethiwekhi isebenza:
- 40- noma 64-bit WEP: ukhiye wezinombolo ezingu-10
- 104- noma 128-bit WEP: ukhiye wamadijithi angu-26
- 256-bit WEP: ukhiye wamadijithi angu-58
Ukuze usize abalawuli ekudaleni okhiye abalungile be-WEP, ezinye izinhlobo zemishini yenethiwekhi engenazintambo zikhiqiza ngokuzenzakalelayo izihluthulelo ze-WEP kusuka embhalweni ovamile (ngezinye izikhathi obizwa ngokuthi i- passphrase ). Ukwengeza, amanye amasayithi eWebhu asesidlangalaleni ahlinzeka ngokuzenzakalelayo okhiye abalulekile be-WEP okwenza amanani angokhiye okungahleliwe aklanyelwe ukuba kube nzima kwabangaphandle ukuqagela.
Kungani i-WEP yaba yinto ebalulekile kumaNethiwekhi angenantambo
Njengoba igama liphakamisa, ubuchwepheshe be-WEP budalwe ngenhloso yokuvikela amanethiwekhi we-Wi-Fi kuze kube amazinga afanayo ukuthi amanethiwekhi e-Ethernet ayevikelwe ngaphambili. Ukuvikeleka kokuxhumeka kwentambo kwakungaphansi kakhulu kunamanethiwekhi amanethiwekhi we- Ethernet lapho i-Wi-Fi yenethiwekhi iqala ukuthandwa. Izinhlelo ezitholakalayo kalula zenethiwekhi ye-network sniffer zavumela noma ubani onolwazi oluncane lwezobuchwephesha ukuthi ahambe ngezindawo zokuhlala bese uthengisa kumanethiwekhi asebenzayo e-Wi-Fi avela emgwaqweni. (Lokhu kwaziwa ngokuthi i- wardriving ,) Ngaphandle kokuthi i-WEP inikwe amandla, abakhohlisi bangabamba kalula futhi babheke amaphasiwedi kanye neminye imininingwana yomuntu siqu engavikelekile emakhaya ayithumela amanethiwekhi awo. Ukuxhumana kwabo kwe-Inthanethi nakho kungafinyelelwa futhi kusetshenziswe ngaphandle kwemvume.
I-WEP yayisodwa ngesikhathi esisodwa esisekelwe kakhulu ekuvikeleni amanethiwekhi we-Wi-Fi ekhaya ngokuhlaselwa okunjalo kwe-sniffer.
Kungani ama-Keys WEP aphelelwe yisikhathi Namuhla
Abacwaningi bezezimboni bagcina bethola futhi benza amaphutha amakhulu omphakathi ekwakhiweni kobuchwepheshe beWEP. Ngamathuluzi afanele (izinhlelo ezakhelwe ukusebenzisa lezi ziphutha zobuchwepheshe), umuntu angangena kumanethiwekhi amaningi avikela i-WEP phakathi nendaba yamaminithi futhi enze uhlobo olufanayo lokuhlasela ukuhlasela njengenethiwekhi engavimbelwe.
Amasistimu ayisihluthulelo amasha angenazintambo ezingenazintambo kuhlanganise ne- WPA ne- WPA2 enziwe kwi-Wi-Fi routers nezinye izinto zokusebenza zokufaka esikhundleni se-WEP. Nakuba amadivaysi amaningi we-Wi-Fi asakunikeza njengento yokukhetha, i-WEP isenesikhathi eside ibhekwa njengengasebenzi futhi kufanele isetshenziswe kumanethiwekhi angenantambo kuphela njengesenzo sokugcina.
