The reason higher performance hardware is needed is that WAP2 uses AES encryption. WPA was designed based on the 802.11a draft and released in 2003, while 802.1H was released in 2004. By the time 802.11i was approved, it had more support for 802.1X and AES/CCMP for encryption. Then the Wi-Fi Alliance released WPA2O, which is compatible with the 802.1H standard.9. The client sends an authentication response.10. The server sends a "pass" or "fail" message. The "pass" message indicates that the client has authenticated successfully.6. PEAPAs seen in EAP-TLS, both the client and the server require a certificate. For EAP-FAST, no certificate is required; instead, the PAC handles everything. For Protected EAP (PEAP, ProtectedEAP), only the server-side certificate is used. Server-side certificates can be used to create tunnels and then perform real authentication internally. The PEAP method was jointly developed by Cisco, Microsoft, and RSA. PEAP uses either Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAPv2) or a GenericTokenCard (GTC) to authenticate users inside the encrypted tunnel.MS-CHAPv2 can be used to authenticate MicrosoftWindows (ActiveDirectory) oThe PEAP process is shown in Figure 17.14.
