Wired Equivalent Privacy ndeyekuyera mitemo protocol inowedzera kuchengeteka kune Wi-Fi nedzimwe nhamba dzisina wireless 802.11 . WEP yakagadzirirwa kupa mitambo isina uteresi iyo yakaenzana yehutano hwekuchengetedza sega yakafanana neyoyo wired network, asi zvikanganiso zvekugadzirisa zvakanyanya zvinogumira.
Ikuti WEP Inoshanda Sei
WEP inoshandisa data encryption scheme iyo inoshandisa kusanganiswa kwevashandi-uye system-yakagadzirwa nheyo dzinokosha. Mishandisirwo yepakutanga yeWEP yakatsigira zvinyorwa zvinyorwa zvemabheti makumi mana pamwe chete nemamwe mabheji makumi mana e-system-generated data, zvichiita kuti zvikwanise zvigaro zvemazana makumi matanhatu. Kuti kuwedzere kuchengetedzwa, nzira idzi dzekunyora dzakapedzerwa kuti dzitsigire zvigaro zvakasara kusanganisira 104-bit (128 bits ye data yose), 128-bit (152 bits zvachose) uye 232-bit (256 bits zvakakwana) kuchinja.
Paunotungamirirwa pamusoro pehutano hweWi-Fi , WEP inonyora ruzivo rwemashoko uchishandisa makiyi kuitira kuti isisakwanise kuverengwa nevanhu asi ichigone kushandiswa kuburikidza nekugamuchira majeri. Zvikwani ivo pachavo havatumire pamusoro pemaketani asi pane zvakachengetwa pamusana usina kambani network adapter kana mu Windows Registry.
WEP uye Home Networking
Vashandi vakatenga 802.11b / g mavheti mumavambo ekutanga kwema 2000s vakanga vasina mavoti ezvokuchengetedza eWi-Fi anowanikwa kunze kweWEP. Yakashandira chinangwa chekudzivirira musha weimba kubva pakangoerekana waiswa kune vavakidzani.
Imba yakawanda yebroadband routers inotsigira WEP inowanzobvumira vatungamiri kupinda mukati machina mana akasiyana-siyana eWEP mu router's console kuitira kuti router inogona kubvumirana kubva kune vatengi vakagadzirirwa neimwe yeiyi. Kunyange zvazvo chiitiko ichi chisingavandudzi kuchengeteka kwehupi hwehutano hwemunhu, inopa vatungamiri dhigirii yakawedzerwa yekugadzirisa kugovera zvigetsi kumakambani ekudhura. Semuenzaniso, muridzi weimba angaratidza chinhu chimwe chete chinogona kushandiswa nevemhuri uye vamwe kune vashanyi. Nechinhu ichi, vanogona kusarudza kuchinja kana kubvisa zvigaro zvevaeni chero nguva yavanoda kunze kwekuchinja mararamiro emhuri.
Chikonzero nei WEP isingakurudzirwi kuti zvishandiswe
WEP yakatangwa muna 1999. Mumakore mashomanana, vatsvakurudzi vakawanda vakachengeteka vakawana zvikanganiso mukugadzira kwayo. I "24 mamwe maitiro e-system-generated data" inotaurwa pamusoro apa inonyatsozivikanwa seIginalization Vector uye yakaratidza kuti ndiyo inonyanya kukosha purogiramu isina kukwana. Nezvinhu zvakajeka uye nyore nyore zvinowanikwa, mutengesi anokwanisa kugadzirisa chinangwa cheWEP uye anoshandisa iyo kupinda muchikamu chekushanda cheWi-Fi mune imwe nyaya yemaminitsi.
Vendor-zvakanatsiridzirwa kuWEP seWEP + uye Dynamic WEP yakashandiswa mukuedza kukanganisa zvimwe zvekukanganisa kweWEP, asi uterevhizheni hahugoneki nhasi.
Kudzokorora kweWEP
WEP yakashandurwa zvepamutemo neWPA muna 2004, iyo yakazobviswa zvakare neWPA2 . Kunyange zvazvo uchitamba neukambani neWEP yakabvumirwa zviri nani pane kushanya pasina kusachengetedzwa kusina wireless encryption zvachose, musiyano hauna hanya kubva mune zvekuchengeteka.
