- The STA send Probe Request to the AP.
- The AP feedback Probe Response to the STA.
- The STA send Authentication (request) to the AP.
- The AP feedback Authentication (response) to the AP.
- The STA send Association Request to the AP.
- The AP feedback Association Response to the STA.
- The AP and the STA Unicast 4-Way handshaking.
- The AP and the STA Multicast / Broadcast 2-Way handshaking.
這一次就直接看AP所發送的Beacon封包。
Mode: WPA and WPA2 Personal Mixed Mode
Cipher Suite: TKIP and CCMP Mixed Mode
- OUI: 00:0F:AC (IEEE 802.11)
- Group Cipher Suite Type: TKIP (2)
- Pairwise Cipher Suite Count: 2
- Pairwise Cipher Suite List:
- Pairwise Cipher Suite Type: AES (CCM) (4)
- Pairwise Cipher Suite Type: TKIP (2)
- Auth Key Management (AKM) Suite Count: 1
- Auth Key Management (AKM) Suite Type: PSK (2)
- RSN Capabilities:
- Management Frame Protection Required: False
- Management Frame Protection Capable: False
由此可見,當使用者設定成WPA and WPA2 – TKIP and CCMP Mixed Mode的時候,Multicast / Broadcast 封包會使用TKIP來加密;而Unicast封包則是有TKIP和CCMP這兩種選擇。
