WEP amaimira Wired Equivalent Privacy, Wi-Fi opanda waya wotetezera muyezo. Chofunika cha WEP ndi mtundu wa chitetezo cha passcode kwa ma Wi-Fi. Makiyi a WEP amathandiza gulu la zipangizo pa intaneti kuti lizitha kusinthanitsa mauthenga amtundu wina mwachinsinsi (mashematically encoded) wina ndi mzake podzibisa zomwe zili mu mauthenga kuti zikhale zosavuta ndi anthu akunja.
Mmene Keys Zagwira Ntchito
Olamulira a pa Intaneti akusankha zomwe WEP angagwiritse ntchito pa makanema awo. Monga mbali imodzi yothandizira WEP chitetezo, makiyi oyenera ayenera kuikidwa pa ma routers komanso chipangizo chilichonse cha makasitomala kuti iwo alankhulane wina ndi mnzake pa kugwirizana kwa Wi-Fi.
Makiyi a WEP ndi ofanana ndi ma values a hexadecimal atengedwa kuchokera ku manambala 0-9 ndi makalata AF. Zitsanzo zina za makiyi a WEP ndi awa:
- 1A648C9FE2
- 99D767BAC38EA23B0C0176D152
Kutalika kofunika kwachinsinsi cha WEP kumadalira mtundu wa WEP momwe maukonde akuyendera:
- 40- kapena 64-bit WEP: chiyilo cha 10
- 104- kapena 128-bit WEP: makilogalamu 26
- 256-bit WEP: chingwe cha 58
Kuti athandize otsogolera pakupanga makiyi oyenera a WEP, zina zamagetsi opanda makina opanga mafoni zimangopanga makiyi a WEP kuchoka pamtima (nthawi zina amatchedwa passphrase ). Komanso, malo ena a pawebusaiti amapereka zowonjezera zowonjezera zowonjezera zowonjezera zowonjezera zomwe zimapanga mfundo zowoneka mosavuta zomwe zimawoneka zovuta kwa akunja kuti aganizire.
Chifukwa chiyani WEP inali Yoyenera kwa Opanda Mauthenga Opanda Mauthenga
Monga momwe dzina limasonyezera, teknoloji ya WEP inalengedwa ndi cholinga choteteza ma Wi-Fi makanema mpaka maulendo ofanana omwe ma Ethernet anatetezedwa kale. Chitetezo cha maulumikiza opanda waya chinali chochepa kwambiri kuposa mawonekedwe a Ethernet wired pamene matepi a Wi-Fi anayamba kutchuka. Mapulogalamu a pulogalamu yamakono omwe amapezeka mosavuta amalola aliyense ali ndi luso lotha kuyendetsa galimoto kupyolera m'madera oyandikana nawo ndikugwiritsira ntchito ma Wi-Fi ogwira ntchito mumsewu. (Izi zinadziwika kuti wardriving ,) Popanda WEP kupatsidwa, sniffers angagwire mosavuta ndi kuwona mawu achinsinsi ndi ma data ena omwe sanatetezedwe amtundu wawo akutumizira pa intaneti zawo. Kuyankhulana kwawo kwa intaneti kungafikiridwe komanso kugwiritsidwa ntchito popanda chilolezo.
Panthawi ina WEP inali yovomerezeka yokhayo yotetezera makanema a Wi-Fi kunyumba.
Chifukwa chiyani WEP Keys Satha Ntchito Masiku Ano
Akatswiri ofufuza mafakitale anapeza ndipo adachita zolakwa zazikulu zapangidwe kawuso wa WEP. Ndi zipangizo zolondola (mapulogalamu omangidwa kuti agwiritse ntchito zolakwika izi), munthu akhoza kulowa mu mawindo ambiri otetezedwa a WEP mkati mwa mphindi zochepa ndikuchita zofanana ndi zida zozizwitsa monga pa intaneti yosateteza.
Zida zatsopano zamakina zam'manja zopanda waya zophatikizapo WPA ndi WPA2 zinawonjezeredwa pa ma-Wi-Fi routers ndi zipangizo zina zomwe zingasinthe WEP. Ngakhale kuti zipangizo zambiri za Wi-Fi zimaperekabe ngati mwayi, WEP wakhala akuonedwa ngati osagwira ntchito ndipo ayenera kugwiritsidwa ntchito pazinthu zopanda mauthenga monga njira yomaliza.
