Eapol 4-way handshake
WebFrom: Ping-Ke Shih If we connect to an AP with WPA2 security, the IQK and the EAPOL 4-way handshake may be failed due to overlap, because driver does IQK right after assoc success. For 802.11n devices, they used to do IQK in driver that could requires more than 100ms to finished. During IQK, any TX/RX events are paused. WebAug 6, 2024 · The PMK is part of the normal 4-way handshake that is used to confirm that both the router and client know the Pre-Shared Key (PSK), or wireless password, of the network.

WebKCK is used to construct MAC in EAPOL packets 2,3 and 4. KEK is used to encrypt some data sent to client(for example GTK). TEK is used for encrypting traffic between client and AP, later during session. Now the WPA 4-way handshake: AP sends ANonse (AP Nonce) to client, which is basically a random Integer of 256 bits.
