I-WEP imele i-Wired Equivalent Ubumfihlo, i- Wi-Fi inethiwekhi yokhuseleko lenethiwekhi. I- key ye-WEP yintlobo yekhowudi yokukhawuleza yokukhusela idivayisi ye-Wi-Fi. Iifayile ze-WEP zinceda iqela lamacebo kwintanethi yendawo ukutshintshisa imfihlo (imathematikhi enekhowudi) omnye nomnye ngelixa lifihla umxholo weemilayezo ngokubukela lula ngabantu bangaphandle.
Indlela yokusebenza yeeWEP
Abalawuli benethiwekhi bakhetha ukuba yiziphi iifayile zeWEP ezisetyenziselwa kwiinkonzo zabo. Njengengxenye yenkqubo yokunika ukhuseleko lweWEP, izitshixo ezifanelwe mazibekwe kwiirhutha kunye nesicatshulwa ngasinye somthengi ukuba bonke baxhumane kunye noxhumo lwe-Wi-Fi.
Iimpawu ze-WEP zilandelelanisa iimpawu ze- hexadecimal ezithathwe kumanani 0-9 kunye nee-AF ezinobumba. Eminye imizekelo yeekhiye zeWEP yile:
- 1A648C9FE2
- 99D767BAC38EA23B0C0176D152
Ubude obufunekayo benkinobho ye-WEP kuxhomekeke kwiyiphi indlela yezinga leWEP inethiwekhi isebenza:
- I-WEP engama-40 okanye ye-64-bit: idijithi ezili-10
- I-WEP engu-104- okanye ye-128-bit: i-26 yenombolo
- I-WEP ye-256-bit: ikhidi engama-58
Ukuncedisa abalawuli ekudaleni iifayile ezifanelekileyo ze-WEP, ezinye iimpawu zesekhaneli zentambo ngokuzenzekelayo zivelise izihluthulelo ze-WEP kwisicatshulwa esiqhelekileyo (ngezinye izihlandlo zibizwa ngokuba yimpasta ). Ukongezelela, ezinye iiWebhu zeeWebhsayithi zinika i-generators e-WEP ngokuzenzekelayo eyenza iimpawu ezingundoqo zengqungquthela ezenzelwe ukuba nzima ukuba ngaphandle baqikelele.
Kutheni i-WEP yayiyeyona nto ibalulekileyo kwiintambo ezingenazintambo
Njengoko igama libonisa, i-WEP iteknoloji yenziwa ngenjongo yokukhusela amanethiwekhi e-Wi-Fi ukuya kumanqanaba afanayo ukuba amanethiwekhi e-Ethernet ayekhuselwe ngaphambili. Ukhuseleko lwamaxhumo angenantambo lwaluphantsi kakhulu kunamanethiwekhi e- Intanethi ye-Ethernet xa inethiwekhi ye-Wi-Fi kuqala yaziwa. Iiprogram ze-network sniffer ezifumaneka ngokulula zivumelekile nabani na abanezakhono zobuchwephesha ukuba baqhube ngeendawo zokuhlala kwaye badonsa kwiinkonzo ezisebenzayo ze-Wi-Fi ezisetratweni. (Oku kwaziwa ngokuba yi- wardriving ,) Ngaphandle kwe-WEP inikwe amandla, i-sniff ingabamba kalula kwaye ibuke iiphasiwedi kunye neminye imininingwane yomntu ongekho mkhuseli ayithumele kwiinqununu zazo. Ukunxibelelana kwabo kwi-intanethi kungasetyenziswa kwaye kusetyenziswe ngaphandle kwemvume.
I-WEP yayisihlandlo esisodwa esekelwe ngokubanzi ekukhuseleni amanethiwekhi e-Wi-Fi asekhaya ekuhlaseleni okunjalo.
Kutheni ii-WEP Keys ezingasetyenziswayo namhlanje
Abaphandi bezoshishino ekugqibeleni bafumene kwaye benza iziphene ezinkulu zikarhulumente kwi-teknoloji yeWEP. Ngezixhobo ezifanelekileyo (iiprogram ezakhelwe ukusetyenziswa kwezi ziphene zezobugcisa), umntu unokungena kumanethiwekhi amaninzi ekhuselekileyo e-WEP ngaphakathi kwimizuzu kwaye enze uhlobo olufanayo lokuhlaselwa ngokubanjelwa kwintanethi engakhuselekanga.
Iinkqubo eziphambili ezingenazintambo ezingenazintambo ezibandakanya iWPA kunye neWPA2 zongezwa kwii-routers ze-Wi-Fi kunye nezinye izixhobo zokutshintsha i-WEP. Nangona iinqununu ezininzi ze-Wi-Fi zisayikhetha njengento yokukhetha, iWEP iye yaqwalaselwa ingagqithwanga kwaye kufuneka isetyenziswe kumanethiwekhi angenawucingo kuphela njengendlela yokugqibela.
