Wi-Fi Tiv Thaiv Kev Nkag Nkag yog Wi-Fi kev ruaj ntseg tshuab tsim los teb rau qhov tsis muaj zog ntawm Wired Equivalent Privacy standard. Nws txhim kho raws li WEP qhov kev lees paub thiab kev encryption nta. WPA2, nyob rau hauv lem, yog ib tug upgraded daim ntawv ntawm WPA; txij li xyoo 2006, txhua yam khoom muaj ntawv pov thawj Wi-Fi yuav tsum siv nws.
WPA Nta
WPA muab kev encryption muaj zog dua WEP siv ob qho ntawm ob tus qauv thev naus laus zis: Temporal key integrity protocol thiab advanced encryption standard. WPA kuj suav nrog kev txhawb nqa kev lees paub ua tiav uas WEP tsis ua.
Qee qhov kev siv ntawm WPA tso cai rau WEP cov neeg siv khoom txuas mus rau lub network, ib yam nkaus, tab sis kev ruaj ntseg raug txo qis rau WEP qib rau txhua yam khoom siv sib txuas.
WPA suav nrog kev txhawb nqa rau cov chaw taws teeb authentication hu-hauv cov neeg siv kev pabcuam servers. Hauv kev teeb tsa no, tus neeg rau zaub mov nkag mus rau cov ntaub ntawv pov thawj ntawm cov cuab yeej kom cov neeg siv txheeb xyuas ua ntej lawv txuas mus rau lub network. Tus neeg rau zaub mov tseem tuav cov lus tshaj tawm kev lees paub tseeb raws tu qauv.
Thaum lub cuab yeej txuas mus rau WPA network, cov yuam sij tsim siv plaub txoj kev tuav tes uas tshwm sim nrog qhov chaw nkag (feem ntau yog router) thiab ntaus ntawv.
Thaum TKIP encryption raug siv, cov lus qhia kev ncaj ncees raug suav nrog kom paub tseeb tias cov ntaub ntawv tsis yog cuav. Nws hloov WEP qhov tsis muaj zog pob ntawv lav, uas yog hu ua cyclic redundancy check.
WPA-PSK yog dab tsi?
WPA Pre-Shared Key yog qhov hloov pauv ntawm WPA tsim los rau kev sib txuas hauv tsev. Nws yog daim ntawv yooj yim tab sis tseem muaj zog ntawm WPA.
Zoo ib yam li WEP, tus yuam sij zoo li qub lossis nqe lus raug teeb tsa, tab sis WPA-PSK siv TKIP. WPA-PSK cia li hloov cov yuam sij ntawm lub sijhawm ua ntej kom ua rau nws nyuaj rau cov neeg nyiag nkas nrhiav thiab siv lawv.
Ua Haujlwm Nrog WPA
Koj yuav pom cov kev xaiv siv WPA rau kev txuas mus rau lub wireless network thiab thaum teeb tsa lub network rau lwm tus los txuas rau. Nws tau tsim los txhawb rau ntawm cov khoom siv ua ntej WPA xws li cov uas siv WEP, tab sis qee qhov ua haujlwm nrog WPA tom qab hloov kho firmware. Lwm tus tsuas yog tsis sib haum.
WPA cov yuam sij sib koom ua ntej yog qhov yooj yim rau kev tawm tsam, txawm tias tus txheej txheem muaj kev nyab xeeb dua li WEP. Koj qhov kev tiv thaiv zoo tshaj plaws yog lo lus zais uas muaj zog txaus los hla kev tawm tsam brute-force.
FAQ
Kuv yuav nrhiav kuv tus yuam sij WPA rau kuv lub router li cas?
Koj lub npe wireless network (SSID) thiab tus yuam sij feem ntau yog luam tawm rau hauv qab ntawm koj lub router. Lub npe network thiab tus yuam sij yuav tsum tsis txhob totaub nrog tus username thiab password, uas yuav tsum tau nkag mus rau qhov chaw router. Yog tias tus yuam sij WPA tau hloov pauv, rov pib dua koj lub router kom rov qab tus yuam sij rau lub neej ntawd.
Qhov txawv ntawm WPA vs. WPA2 vs. WPA3 yog dab tsi?
Qhov sib txawv loj ntawm WPA thiab WPA2 yog tias WPA2 muaj kev nkag siab zoo dua. Tus qauv tshiab tshaj plaws yog WPA3, uas muaj kev ruaj ntseg zoo rau kev qhib tes hauj lwm.
Kuv yuav paub li cas yog kuv lub router yog WEP lossis WPA?
Ntawm Windows 10, xaiv lub Wi-Fi icon hauv lub taskbar, xaiv Properties hauv qab lub network koj tam sim no txuas nrog Tom qab ntawd nrhiav tus Security Type Ntawm Mac, tuav lub Option tus yuam sij thiab xaiv qhov Wi-Fiicon nyob rau hauv lub toolbar kom pom koj cov ntaub ntawv network. Hauv Android, mus rau koj qhov kev sib txuas Wi-Fi thiab coj mus rhaub lub network kom pom nws cov ntsiab lus.
