802.11i is an IEEE wireless LAN security standard created as a more permanent solution after WEP vulnerabilities were discovered. WPA2 adopted 802.11i. section 20.5
Its role is to strengthen authentication and encryption for 802.11 networks. It belongs to the progression from WEP, through interim WPA, to WPA2 and later WPA3. section 20.5
Key relationships include:
- WEP uses RC4 encryption and an integrity check value, but its vulnerabilities motivated stronger alternatives. section 20.5
- WPA served as an interim enhancement before 802.11i was completed and adopted by WPA2. section 20.5
- WPA-Personal and WPA-Enterprise provide deployment-oriented authentication choices associated with the WPA family. section 20.5
