WPA Lus Txhais thiab Lus Qhia
WPA sawv cev rau Wi-nkaus Tiv Thaiv, thiab yog lub tshuab kev ruaj ntseg rau Wi-nkaus tes hauj lwm. Nws tau tsim los ntawm cov lus teb rau cov kev qaug zog ntawm WEP (Wired Equivalent Privacy) , thiab yog li ua rau kev txhim kho ntawm WEP's authentication thiab encryption nta.
WPA2 yog ib qho WPA hloov tshiab; txhua qhov Wi-nkaus tau ntawv pov thawj khoom tau siv los siv WPA2 txij thaum 2006.
Ntsis: Saib Dab tsi yog WEP, WPA, thiab WPA2? Qhov twg yog qhov zoo? kom paub ntau ntxiv txog kev yuav WPA li cas rau WPA2 thiab WEP.
Lus Cim: WPA kuj tseem yog ib qho tseem ceeb rau qhov Kev Tshawb Fawb Qhov Tshawb Fawb, tab sis nws tsis muaj dab tsi ua rau kev ruaj ntseg wireless.
WPA Ntaus
WPA muaj kev ruaj khov dua WEP los ntawm kev siv ob ntawm cov txheej txheem technologies: Temporal Key Integrity Protocol (TKIP) thiab Advanced Encryption Standard (AES) . WPA kuj muaj xws li kev pabcuam uas tau tsim los ntawm WEP tsis muaj.
Qee qhov kev siv ntawm WPA cia rau WEP cov neeg tau txais kev txuas mus rau lub network dhau, tab sis qhov kev nyab xeeb yog muab txo mus rau WEP-theem rau tag nrho cov cuab yeej sib txuas.
WPA suav nrog kev pabcuam rau qhov kev pabcuam uas yog hu ua Chaw Tiv Tojcais Tshaj Lawm Dial-In User Service, lossis RADUIS servers. Nws yog tus neeg saib xyuas no uas tau nkag mus rau cov ntawv qhia kev ntaus ntawv kom cov neeg siv tau tuaj yeem ua pov thawj ua ntej lawv txuas rau lub network, thiab qhov ntawd kuj tau tuav EAP (Extensible Authentication Protocol).
Thaum ib tug ntaus ntawv sib txuas mus rau WPA network, hauv lub lag luam yog tsim los ntawm plaub-txoj kev sib tuav tes uas siv qhov chaw nkag (feem ntau yog router ) thiab ntaus ntawv.
Thaum siv TKIP encryption, ib tsab xov xwm kev cai ncaj ncees (MIC) yog los xyuas kom meej tias cov ntaub ntawv tsis yog kev txuam nrog. Nws hloov qhov WEP cov ntawv qis zog uas tau hu ua kev hloov qis dua (CRC).
WPA-PSK Yog Dab Tsi?
Ib qho kev hloov ntawm WPA, tsim los siv nyob rau hauv lub network networks, hu ua WPA Pre-Key Key, lossis WPA-PSK. Nws yog ib qho yooj yim tab sis tseem muaj zog ntawm WPA.
Nrog WPA-PSK, thiab zoo ib yam li WEP, ib qhov tseem ceeb lossis muaj cai caij nyoog, tab sis nws siv TKIP. WPA-PSK yuav hloov cov yawm sij ntawm lub sij hawm ua ntej lub sij hawm yuav ua rau nws nyuaj rau cov nyom ntau dua thiab nrhiav lawv.
Ua haujlwm nrog WPA
Cov kev siv rau kev siv WPA yog pom thaum txuas mus rau ib qho wireless network thiab thaum tsim kom tau ib lub network rau lwm tus neeg txuas rau.
WPA tau tsim los txhawb rau WPA ua ntej xws li cov neeg siv WEP, tabsis qee cov haujlwm tsuas yog ua haujlwm nrog WPA tom qab hloov kho cov lag luam thiab lwm tus tsis txaus siab.
Saib Yuav Ua Li Cas Pab Txhawb Kev Siv WPA ntawm Lub Wireless Network thiab Yuav Pab Kho WPA Kev Pabcuam hauv Microsoft Yog tias koj xav tau kev pab.
WPA tau muab cov kab lus tso npe ua ntej tseem muaj kev ywj pheej rau cov kev tawm tsam txawm tias qhov kev cai lij choj tsis ruaj ntseg ntau dua WEP. Nws yog ib qho tseem ceeb, ces, los xyuas kom meej tias cov passphrase yog qhov muaj zog txaus kom tsis muaj zog ntawm kev quab yuam tawm tsam.
Saib Yuav Ua Li Cas Ua Tau Tus Peev Xwm Muaj Zog rau tej lub tswv yim, thiab tsom xyuas kom dhau 20 cim rau WPA password.
