WebThe 802.11i key derivation procedure is based on a 4‐way handshake. The primary activities in a 4‐way handshake are to verify the existence of the same Pairwise Master Key (PMK) between the client and the AP and to derive the Pairwise Transient Key (PTK). The 4‐way handshake consists of four messages, from Message‐1 to Message‐4. WebJun 18, 2024 · The 4-way handshake is the process of exchanging 4 messages between an access point (authenticator) and the client device (supplicant) to generate some encryption keys which can be used to encrypt actual data sent over Wireless medium.
