Farqiga u dhexeeya WPA, WPA2 & WEP Wi-Fi borotokoolka

Waxaa jira khataro badan oo la taaban karo oo la xiriira borotokoolka wireless-ka iyo hababka sirta. Sidaa darteed, si loo yareeyo iyaga waxaa la isticmaalaa qaab-dhismeedka adag ee borotokoolka amniga wireless-ka ee kala duwan. Hab -maamuusyada Amniga Wireless-(Wireless Security Protocols) ka waxay xaqiijinayaan ka hortagga gelitaanka aan la oggolayn ee kombuyuutarrada iyagoo sir xogta la gudbiyo ee shabakadda wireless-ka.

Farqiga u dhexeeya WPA2 , WPA , WEP Wi-Fi borotokoolka(WEP Wi-Fi Protocols)

WPA2, WPA, WEP Wi-Fi borotokoolka

Inta badan dhibcooyinka gelitaanka wirelessku waxay la yimaadaan karti ay ku suurtageliso mid ka mid ah saddexda halbeeg ee sireeynta wireless:

  1. WEP (Sirta u dhiganta ee Wired)
  2. WPA ama Wi-Fi galitaanka la ilaaliyo
  3. WPA2

WEP ama Qarsoodi u dhigma ee Wired

Shabakadda amniga wireless-ka ee ugu horreysay ee calaamadisa muuqaalkeeda waxay ahayd WEP ama Qarsoodi u dhiganta ee Wired(Wired Equivalent Privacy) . Waxay ku bilaabantay 64-bit encryption (daciif) oo aakhirkii waxay tagtay ilaa 256-bit encryption (xoog leh). Hirgelinta ugu caansan ee router-yada waxay ku sii socotaa inay noqoto 128-bit encryption (dhexdhexaad ah).

Waxaa loo tixgeliyey inay tahay xalka ugu dambeeya ilaa cilmi-baarayaasha amnigu ay ka heleen dhowr dayacan oo ku dhex jira taas oo u ogolaatay tuugada inay jebiyaan furaha WEP dhowr daqiiqo gudahood. (WEP)Waxay adeegsatay CRC ama Hubinta Dib-u-celinta Cyclic(Cyclic Redundancy Check) .

WPA ama Wi-Fi galitaanka la ilaaliyo

Si wax looga qabto cilladaheeda, WPA waxaa loo sameeyay sidii halbeeg ammaan oo cusub oo loogu talagalay borotokoolka wireless-ka. Waxay adeegsatay TKIP ama borotokoolka daacadnimada furaha(Temporal Key Integrity Protocol) ku meel gaadhka ah si loo hubiyo daacadnimada fariinta. Tani waxay kaga duwanayd WEP qaab ahaan, kii hore ee la isticmaali jiray CRC ama Hubinta Dib-u-noqoshada Wareegga(Cyclic Redundancy Check) . TKIP waxa la rumaysnaa in uu aad uga xoog badan yahay CRC . Isticmaalkeeda waxay xaqiijisay in baakidh kasta oo xog ah lagu soo diray fure qarsoodi ah oo gaar ah. Isku darka furuhu waxa uu kordhiyey kakanaanta furayaasha furaha oo sidaas awgeed hoos u dhigaya dhacdooyinka farogelinta . (Key)Si kastaba ha noqotee, sida WEP , WPA sidoo kale waxay lahayd cillad. Sidan oo kale, WPAwaxaa loo hormariyay WPA 2 .

WPA2

WPA 2 waxaa hadda loo aqoonsan yahay borotokoolka ugu ammaansan. Isbeddelka kaliya ee ugu muhiimsan ee ka dhex muuqda WPA iyo WPA2 waa isticmaalka qasabka ah ee AES ( Advanced Encryption Standard)  algorithms iyo hordhaca CCMP (Counter Cipher Mode with Block Chaining Message Athentication Code Protocol)(CCMP (Counter Cipher Mode with Block Chaining Message Authentication Code Protocol)) beddelka TKIP.

Habka CCM waxa uu isku daraa sirta qaabka Counter ( CTR ) iyo (CTR)aqoonsiga Cipher Block Chaining Message Code(Cipher Block Chaining Message Authentication Code) ( CBC-MAC ). Hababkan si weyn baa loo dersay waxaana la ogaaday inay leeyihiin sifooyin qarsoodi ah oo si wanaagsan loo fahmay kuwaas oo siinaya ammaan wanaagsan iyo waxqabadka software ama hardware.
