Final answer:
WPA2 utilizes a 4-way handshake to establish a secure connection between a station and an access point, authenticating credentials and exchanging an encryption key for secure data communication.
Step-by-step explanation:
The technology that uses a 4-way handshake to allow a station to associate with an access point, authenticate its credentials, and exchange a key to use for data encryption is WPA2 (Wi-Fi Protected Access 2). This security protocol is implemented in most modern Wi-Fi networks to provide secure communication over the airwaves. The 4-way handshake process involves confirming that both the station (such as a laptop or smartphone) and the access point have the correct credentials, and then establishing a new encryption key to protect the data that will be sent between them.
