  • The next installment of the WPA trilogy has been required for new devices since July 1, 2020.[10]
  • If it’s an option, choose WPA2 or WPA3.[10]
  • No wonder, then, that WPA2 offered no streamlined way to safely onboard these devices to an existing Wi-Fi network.[11]
  • (WPA2) are security standards to protect network stations connected to WiFi networks.[12]
  • -Fi Protected Access (WPA) was supported in IEEE 802.11i wireless networks and was proposed in 2004.[12]
  • The encryption method adopted in WPA is the Temporal Key Integrity Protocol (TKIP).[12]
  • -Fi Protected Access II (WPA2) aims for complete compatibility with IEEE802.11i standard that was partially achieved by WPA.[12]
  • WPA includes support for remote authentication dial-in user service servers.[13]
  • WPA Pre-Shared Key is a variation of WPA designed for home networks.[13]
  • Similar to WEP, a static key or passphrase is set, but WPA-PSK uses TKIP.[13]
  • You'll see options for using WPA for connecting to a wireless network and when setting up a network for others to connect to.[13]
  • Definition - What does Wi-Fi Protected Access (WPA) mean?[14]
  • So the WiFi Protected Access standard was developed, or WPA for short.[15]
  • The main weakness of WPA was that it was designed to use some of the same vulnerable technologies that WEP used.[15]
  • But that’s because WPA was designed so that devices that were made to use WEP could use the more secure WPA with a software update.[15]
  • Without getting into too much technical jargon, cyber attackers found a way to bypass WPA2 encryption through WPS.[15]
  • WPA is an authentication and key management (AKM) protocol developed by the Wi-Fi alliance.[16]
  • A session key in WPA2 is computed from a pre-shared password and some publicly known values.[16]
  • WPA2 produces a 384-bit secret key called PTK.[16]
  • The Wi-Fi protected setup (WPS) is a feature in WPA2 for a convenient and fool-proof setup for accessing the Wi-Fi network.[16]
  • " WPA is a security protocol designed to create secure wireless (Wi-Fi) networks.[17]
  • WPA also implements something called the Extensible Authentication Protocol (EAP) for authorizing users.[17]
  • Instead of authorizing computers based soley on their MAC address, WPA can use several other methods to verify each computer's identity.[17]
  • It was replaced by the original Wi-Fi Protected Access (WPA) in 2003 as an interim solution to the limited protection offered by WEP.[18]
  • WPA was replaced in 2004 with more advanced protocols of WPA2.[18]
  • Though the threat of a security compromise is small, users should not purchase new equipment which supports only WPA with TKIP.[18]
  • When a wireless vendor wants WPA certification, its wireless hardware has to go through a testing process in authorized testing labs.[19]
  • The first wireless devices were certified for WPA (version 1) in 2003.[19]
  • WPA is the Wi-Fi Alliance’s answer to replace WEP with all its vulnerabilities.[19]
  • WPA uses Temporal Key Integrity Protocol (TKIP), which recycled some items from WEP; it still uses the RC4 algorithm.[19]
  • WPA (sometimes referred to as the draft IEEE 802.11i standard) became available in 2003.[20]
  • The WPA protocol implements much of the IEEE 802.11i standard.[20]
  • Specifically, the Temporal Key Integrity Protocol (TKIP) was adopted for WPA.[20]
  • WPA also includes a Message Integrity Check, which is designed to prevent an attacker from altering and resending data packets.[20]
  • Wi-Fi Protected Access (WPA) is a security standard for users of computing devices equipped with wireless internet connections.[21]
  • The enterprise mode, WPA-EAP, uses more stringent 802.1x authentication with the Extensible Authentication Protocol (EAP).[21]
  • The personal mode, WPA-PSK, uses preshared keys for simpler implementation and management among consumers and small offices.[21]
  • WPA provides strong user authentication based on 802.1x and the Extensible Authentication Protocol (EAP).[21]
  • TKIP was designed to be efficient enough to work in older WEP devices by updating their firmware to WPA.[22]
  • In addition to TKIP, WPA2 supports the AES-CCMP encryption protocol.[22]
  • AES-CCMP requires more computing power than TKIP, and migration from WEP to WPA2 requires new hardware.[22]
  • WPA2 is based on the ratified version of the IEEE 802.11i standard.[23]
  • This makes it quite different from plain WPA, which was a stop-gap measure based on draft versions of the IEEE 802.11i standard.[23]
  • It should be noted that WPA is an interim standard that will be replaced with the IEEE��s 802.11i standard upon its completion.[24]
  • Before setting up WPA2 on your network, make sure that all connected devices can support this security protocol.[25]
  • You should also check with your internet service provider to see if WPA2 is already elected for your network.[25]
  • You will likely see an option for WEP, WPA, and WPA2.[25]
  • WPA or Wi-Fi Protected Access, is a Wi-Fi security standard that's intended to replace the older WEP, or Wired Equivalent Privacy.[26]
  • WEP was supposed to keep Wi-Fi networks secure but turned out to be very easy to break, so it's been deprecated in favor of WPA.[26]
  • Well, one thing she would have read is that one major improvement of WPA over WEP is the length of the encryption keys.[26]
  • WPA uses a 256-bit key, where WEP used 64-bit and 128-bit keys.[26]
  • WPA stands for Wi-Fi Protected Access.[27]
  • The WPA was released in 2003 as an interim standard to answer the immediate need for a more secure protocol.[27]
  • Unlike the 64 and 128-bit keys of WEP, WPA keys use 256-bit keys.[27]
  • Meanwhile, one of the upgrades provided in WPA was the incorporation of message integrity checks.[27]
