What is a 4-way TCP-handshake?
A four-way handshake is a type of network authentication protocol established by IEEE-802.11i that involves standards set up for the construction and use of wireless local area networks (WLANs). The four-way handshake provides a secure authentication strategy for data delivered through network architectures.
How do you do a 4-way handshake?
The 4-Way Handshake utilizes an exchange of four EAPOL-Key frames between the client and access point. In a PSK network, the exchange of frames occurs after the Open System Authentication and Association. In an 802.1X network, the 4-Way Handshake occurs after EAP authentication.
How do you do a TCP-handshake?
TCP Three-Way Handshake. The client chooses an initial sequence number, set in the first SYN packet. The server also chooses its own initial sequence number, set in the SYN/ACK packet shown in Figure 3.8. Each side acknowledges each other’s sequence number by incrementing it; this is the acknowledgement number.
Why TCP uses 4 way finishing for connection termination instead of 3way like connection establishment?
In connection Termination : it takes four segments to terminate a connection since a FIN and an ACK are required in each direction. (3) means that sometime later the application that received the end-of-file will close its socket. This causes its TCP to send a FIN.
What is EAPOL key?
EAPOL (EAP over LAN) is the method used by WPA2 to exchange identities in both WPA2/PSK and WPA2/802.1x (Enterprise) modes and to install the keys to establish an encrypted connection. Within WPA2, if a response is not received by a station (client) it can request a resend.
What does TCP stand for?

Transmission Control Protocol (TCP)
What is handshake in networking?
Term used to describe the process of one computer establishing a connection with another computer or device. The handshake is often the steps of verifying the connection, the speed, or the authorization of a computer connection. An example of handshaking is when a modem connects to another Modem.

What is a 4-way handshake?
So, let’s start with… 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.
Why does TCP Connect termination need 4-Way Handshake?
Since the Four main steps are required to close an active connection, so, it is called a four-way handshake. For a better understanding, you can take a look at the diagram below: Why Does TCP Connect Termination Need 4-way-Handshake?
