56 WiFi Hijacking Preshared Key Part 1

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. These keys which are generated through 4-way handshake are generated by some source key material which will be discussed later. If you do not want to get confused about the terminologies used in 4-way handshake then let’s have a quick look. Let’s see what terminologies we might come across to understand 4-way handshake. I would say don’t be scared of these terminologies. It’s like much ado about nothing.
