Momwe WEP amagwirira ntchito
WEP imagwiritsa ntchito ndondomeko yoyendetsera deta yomwe imagwiritsira ntchito magulu othandizira okhudzidwa ndi ogwiritsira ntchito-ndi njira. Zolemba zoyambirira za WEP zinkathandiza makina okwana 40 ophatikizira kuphatikizapo zigawo zina 24 zowonjezera, zomwe zimabweretsa makiyi 64 autali wonse. Poonjezera chitetezo, njirazi zikutchulidwanso kuti zithandizire makina aatali-104-bit (128 bits total data), 128-bit (152 bits okwana) ndi 232-bit (256 bits totali) kusiyana.
Pogwiritsa ntchito kugwirizana kwa Wi-Fi , WEP imalemba mtsinje wa deta pogwiritsa ntchito makiyiwa kotero kuti sichiwerenganso anthu koma komabe imatha kusinthidwa pozilandira zipangizo. Makinawo samatumizidwa pa intaneti koma amakhala osungiramo makina opanda waya kapena Windows Registry.
WEP ndi Home Networking
Ogula omwe anagula ma 802.11b / g oyendetsa kumayambiriro kwa zaka za 2000 analibe njira zotetezera za Wi-Fi zomwe zilipo kupatulapo WEP. Linagwiritsa ntchito cholinga chachikulu chotetezera makompyuta a nyumba kuchokera kumalo osungirako anthu.
Mayendedwe apakompyuta omwe amathandizira WEP amavomereza kuti olamulira azilowetsa makiyi a WEP osiyana mu router's console kotero kuti router ikhoze kulandira mauthenga kuchokera kwa makasitomala omwe akukhazikitsidwa ndi iliyonse ya mafungulo awa. Ngakhale kuti mbaliyi siipititsa patsogolo chitetezo cha mgwirizano uliwonse, imapatsa olamulira mphamvu yowonjezereka yosagawira makiyi a makasitomala. Mwachitsanzo, mwini nyumba angapange fungulo limodzi loti ligwiritsidwe ntchito ndi mamembala komanso ena kwa alendo. Ndi mbali iyi, akhoza kusankha kusintha kapena kuchotsa mafungulo a alendo pamene akufuna koma osasintha zokhazokha za banja.
Chifukwa chiyani WEP Sipangidwe Kuti Zigwiritsidwe Ntchito Zonse

Ndi zida zophweka komanso zosavuta, wowononga angathe kudziwa chofunika cha WEP ndikuchigwiritsa ntchito kuti mulowe muchitetezo cha Wi-Fi mkati mwa mphindi zochepa.
Zowonjezera zotsatsa malonda kwa WEP ngati WEP + ndi Dynamic WEP zinayesedwa poyesera kukonza zina mwa zolephera za WEP, koma zipangizo zamakonozi sizingatheke lero.
