WEP sawv cev rau Wired Equivalent Privacy, Wi-Fi wireless network kev ruaj ntseg tus qauv. Tus yuam sij WEP yog tus lej hla kev nyab xeeb rau Wi-nkaus khoom siv. WEP cov yawm sij ua rau cov khoom siv hauv lub network hauv zos los pauv cov lus encrypted (lej encoded) sib tham thaum zais cov ntsiab lus ntawm cov lus los ntawm kev saib yooj yim los ntawm cov neeg sab nraud.
How WEP Keys Ua Haujlwm
Network cov thawj coj xaiv cov yuam sij WEP siv rau hauv lub network. Raws li ib feem ntawm cov txheej txheem ntawm kev ua kom muaj kev ruaj ntseg WEP, cov yuam sij sib txuam yuav tsum tau teeb tsa ntawm routers nrog rau txhua tus neeg siv khoom siv rau lawv sib txuas lus nrog ib leeg dhau ntawm kev sib txuas Wi-Fi.
WEP cov yuam sij yog ib ntu ntawm qhov tseem ceeb hexadecimal coj los ntawm cov lej 0 txog 9 thiab cov ntawv A txog F. Qee qhov piv txwv ntawm WEP cov yuam sij yog:
- 1A648C9FE2
- 99D767BAC38EA23B0C0176D152
Qhov ntev ntawm tus yuam sij WEP nyob ntawm seb tus qauv ntawm WEP tus qauv lub network khiav:
- 40- lossis 64-ntsis WEP: 10 tus lej yuam sij
- 104- lossis 128-ntsis WEP: 26 tus lej yuam sij
- 256-ntsis WEP: 58 tus lej tseem ceeb
Txhawm rau pab cov thawj coj hauv kev tsim cov yuam sij WEP kom raug, qee lub npe ntawm cov khoom siv wireless network tau tsim cov yuam sij WEP los ntawm cov ntawv nyeem tsis tu ncua (qee zaus hu ua passphrase). Tsis tas li ntawd, qee lub vev xaib pej xeem muab cov tshuab hluav taws xob tsis siv neeg WEP uas tsim cov txiaj ntsig tseem ceeb uas nyuaj rau cov neeg sab nrauv twv.
Vim li cas WEP yog ib qho tseem ceeb rau Wireless Networks
Raws li lub npe qhia, WEP thev naus laus zis tau tsim los tiv thaiv Wi-nkaus tes hauj lwm mus txog qib sib npaug uas Ethernet network tau tiv thaiv. Kev ruaj ntseg ntawm kev sib txuas wireless tau tsawg dua li ntawm wired Ethernet tes hauj lwm thaum Wi-Fi networking thawj zaug tau nrov.
Network sniffer cov kev pab cuam tso cai rau ib tus neeg uas muaj kev paub me ntsis kom tsav tsheb los ntawm cov neeg nyob ib puag ncig thiab coj mus rhaub rau hauv Wi-nkaus tes hauj lwm los ntawm txoj kev. Qhov no tau los ua lub npe hu ua wardriving. Yog tsis muaj WEP enabled, sniffers tuaj yeem ntes thiab saib cov passwords thiab lwm cov ntaub ntawv ntiag tug uas tsis muaj kev tiv thaiv tsev neeg xa mus rau lawv lub network. Lawv cov kev sib txuas hauv is taws nem tseem tuaj yeem ncav cuag thiab siv yam tsis tau tso cai.
WEP yog tib lub sijhawm tsuas yog tus qauv txhawb nqa dav dav rau kev tiv thaiv hauv tsev Wi-nkaus tes hauj lwm tawm tsam sniffer tawm tsam.
Vim li cas WEP Keys tsis siv hnub no
Cov kws tshawb fawb kev lag luam tau tshawb pom thiab ua rau pej xeem qhov tsis txaus ntseeg hauv kev tsim WEP thev naus laus zis. Nrog rau cov cuab yeej tsim nyog (xws li cov kev pab cuam tsim los siv cov kev tsis zoo no), ib tus neeg tuaj yeem nkag mus rau hauv feem ntau WEP cov tes hauj lwm tiv thaiv nyob rau hauv ob peb feeb thiab ua tib yam sniffing tawm tsam ib yam li ntawm lub network tsis muaj kev tiv thaiv.
Ntau dua thiab siab dua wireless cov tshuab tseem ceeb suav nrog WPA thiab WPA2 tau ntxiv rau Wi-Fi routers thiab lwm yam khoom siv los hloov WEP. Txawm hais tias muaj ntau yam khoom siv Wi-Fi tseem muab nws los ua ib qho kev xaiv, WEP tau raug txiav txim siab ntev dhau los thiab yuav tsum tau siv rau hauv cov tes hauj lwm wireless nkaus xwb.
FAQ
Koj tuaj yeem pom tus yuam sij WEP ntawm iPhone li cas?
Yog koj tab tom nrhiav WEP rau lub xov tooj hotspot, feem ntau koj tuaj yeem pom hauv Settings > Cellular >Tus kheej Hotspot.
Tus yuam sij WEP yog dab tsi rau Nintendo DS?
Tus yuam sij WEP ntawm Nintendo DS ua haujlwm tib yam li WEP tus yuam sij rau lub PC lossis lub xov tooj ntawm tes. Nws yog ib txheej ntxiv ntawm kev ruaj ntseg ntawm lub handheld console thiab Wi-Fi network nws txuas nrog.
