WPA Tsanangudzo uye Tsanangudzo
WPA inomiririra Wi-Fi Protected Access, uye inyanzvi yehutano ye Wi-Fi network. Yakave yakagadziriswa pakupindura kushaya simba kweWEP (Wired Equivalent Privacy) , uye naizvozvo inovandudza pane zvinyorwa zveWEP uye zvinyorwa.
WPA2 inzira yakagadziridzwa yeWPA; mhando yese ye-Wi-Fi yakagadziriswa yakashandisa WPA2 kubva muna 2006.
Zano: Ona Chii WEP, WPA, uye WPA2? Ndeipi Yakanakisisa? kuti uwane mamwe mashoko pamusoro pekuti WPA inofananidzwa sei neWPA2 neWEP.
Cherechedza: WPA ichinyorwawo cheWindows Performance Analyzer, asi hachina chokuita nehutano husina tsvina.
WPA Features
WPA inopa kuwedzera zvakasimba kupfuura WEP kuburikidza nekushandiswa kweimwe yemhando mbiri dzekombiyuta: Temporal Key Integrity Protocol (TKIP) uye Advanced Encryption Standard (AES) . WPA inosanganisirawo yakagadzirirwa mukati mekutsigirwa kutsigirwa izvo WEP haina kupa.
Zvimwe zvinogadziriswa zveWPA zvinobvumira vashandi veWEP kuti vauye kunewo network, asi kuchengetedzwa kunobva kwaderedzwa kusvika kumaWEP-mazinga ezvose zvakagadzirwa.
WPA inosanganisira kutsigirwa kwekutendesa kunoshevedzwa kunonzi Remote Authentication Dial-In User Service seva, kana ma server RADUIS. Ndiyo sevha iyo ine ruzivo rwezvikwangwani zvekushandisa kuitira kuti vashandise vagone kuvimbiswa vasati vambobatanidza kunhare, uye iyo inogonawo kubata EAP (Extensible Authentication Protocol).
Kamwe kana chipikicha ichibudirira kubudirira kune network yaWPA, makii anogadzirwa nenzira yekubatana kwemaoko mana inowanikwa nehuwandu hwekuwana (kazhinji router ) uye chigadzirwa.
Apo TKIP kuvharidzira inoshandiswa, shoko rehutenderedzwa hwekodzero (MIC) rinosanganiswa kuti rive nechokwadi chokuti data haisi kuchinjwa. Inotora nzvimbo yeWEP isina simba rakagadziriswa yeplateti inonzi cyclic redundancy check (CRC).
Chii Chinonzi WPA-PSK?
Kusiyana kweWPA, yakagadzirirwa kushandiswa pamakambani epamba, inonzi WPA Pre Shared Key, kana WPA-PSK. Ndiyo nzira yakaoma asi yakasimba yeWPA.
NeWPA-PSK, uye yakafanana neWEP, kamba yakasimba kana kuti passphrase inogadzirirwa, asi inoshandisa TKIP. WPA-PSK inofanirwa kuchinja zvigetsi panguva yakatarisa nguva yekuita kuti zvive zvakaoma zvikuru kuvaseki kuti vawane uye vashandise.
Kushanda neWPA
Zvisarudzo zvekushandisa WPA zvinowanikwa paanosangana kune network isina wire uyewo apo pawakagadzira imwe network kuti vamwe vauye.
WPA yakagadzirirwa kushandiswa pamagetsi e-WPA asati akafanana neaya ari kushandisa WEP, asi vamwe vanoshanda chete neWPA mushure mekusimudzira firmware uye vamwe havakwanisi.
Ona Nzira Yokugonesa WPA pane Wireless Network uye Nzira Yokugadzira WPA Support mune Microsoft Windows kana uchida rubatsiro.
WPA inotanga kugoverana makiki achiri kutambudzwa kurwisa kunyange zvazvo protocol iri yakachengeteka kupfuura WEP. Zvakakosha, saka, kuve nechokwadi chokuti passphrase yakasimba zvakakwana kudzivisa kushandiswa kwechisimba kwechisimba.
Ona Nzira Yokuita Nesimboti Yakasimba sei mazano, uye chinangwa chemashoko anopfuura makumi maviri eWPA password.
