WPA3 Security yog dab tsi?
WPA3, tseem hu ua Wi-Fi Protected Access 3, sawv cev rau tiam tshiab ntawm kev ruaj ntseg tseem ceeb hauv cov tes hauj lwm wireless. Piv nrog rau tus qauv nrov WPA2 (tso tawm hauv 2004), nws nce qib kev ruaj ntseg thaum tswj kev rov qab sib raug zoo.
Tus qauv WPA3 yuav encrypt tag nrho cov ntaub ntawv ntawm pej xeem Wi-Fi tes hauj lwm thiab tuaj yeem tiv thaiv kev ruaj ntseg Wi-Fi tes hauj lwm ntxiv. Tshwj xeeb tshaj yog thaum cov neeg siv siv pej xeem network xws li tsev so thiab neeg ncig teb chaw Wi-Fi hotspots, tsim kom muaj kev ruaj ntseg txuas nrog WPA3 ua rau nws nyuaj rau cov neeg nyiag nkas kom tau txais cov ntaub ntawv ntiag tug. Siv WPA3 raws tu qauv ua rau koj lub network Wi-Fi tiv thaiv kev nyab xeeb zoo li offline phau ntawv txhais lus tawm tsam.
WPA3 Kev Ruaj Ntseg Tseem Ceeb Nta
1. Kev tiv thaiv muaj zog txawm tias tsis muaj passwords
Hauv WPA2, muaj qhov tsis zoo hu ua "Krack" tau tshawb pom uas siv qhov no thiab tso cai rau kev nkag mus rau hauv lub network yam tsis muaj passphrase lossis Wi-Fi password. Txawm li cas los xij, WPA3 muab kev tiv thaiv zoo dua tiv thaiv cov kev tawm tsam no. Lub kaw lus cia li tiv thaiv kev sib txuas los ntawm kev tawm tsam zoo li no txawm tias tus neeg siv xaiv lo lus zais lossis tus lej zais tsis ua raws li qhov xav tau yam tsawg kawg nkaus.
2. Kev sib txuas yooj yim rau cov khoom siv tsis muaj zaub
Tus neeg siv yuav tuaj yeem siv nws lub xov tooj lossis ntsiav tshuaj los teeb tsa lwm lub cuab yeej IoT me zoo li lub xauv ntse lossis lub tswb kom teeb tus password es tsis txhob qhib nws rau leej twg nkag mus thiab tswj.
3. Kev tiv thaiv tus kheej zoo dua ntawm kev sib koom tes
Thaum tib neeg siv cov kev sib txuas lus pej xeem uas tsis tas yuav tsum muaj tus password los txuas (xws li cov uas pom hauv khw noj mov lossis tshav dav hlau), lwm tus tuaj yeem siv cov tes hauj lwm uas tsis tau encrypted los nyiag lawv cov ntaub ntawv tseem ceeb.
Niaj hnub no, txawm hais tias tus neeg siv txuas nrog rau qhov qhib lossis kev sib txuas rau pej xeem, WPA3 system yuav encrypt qhov kev sib txuas thiab tsis muaj leej twg tuaj yeem nkag mus rau cov ntaub ntawv xa mus ntawm cov khoom siv.
4. 192-ntsis Security Suite rau tsoom fwv
WPA3's encryption algorithm tau hloov kho mus rau 192-ntsis CNSA qib algorithm, uas WiFi Alliance piav qhia tias yog "192-ntsis kev ruaj ntseg suite". Cov suite tau sib haum nrog National Security Systems Council National Commercial Security Algorithm (CNSA) suite, thiab yuav tiv thaiv Wi-Fi tes hauj lwm ntxiv nrog rau kev ruaj ntseg siab dua, suav nrog tsoomfwv, kev tiv thaiv, thiab kev lag luam.
