WPA2-PSK, also known as Wi-Fi Protected Access II Pre-Shared Key, is a security protocol used to secure wireless networks. It is a widely adopted standard for protecting Wi-Fi connections from unauthorized access. The "PSK" part signifies that a pre-shared key, essentially a password, is used for authentication. Both the wireless access point and the client devices attempting to connect must use the same pre-shared key.

WPA2-PSK employs the Advanced Encryption Standard (AES) cipher for data encryption, providing a strong level of security. During the connection process, a four-way handshake occurs between the access point and the client. This handshake exchanges temporary keys derived from the pre-shared key, ensuring that the actual data transmitted is encrypted. This method helps to prevent eavesdropping and man-in-the-middle attacks.

While WPA2-PSK offers robust security for most home and small office networks, it is important to use a strong, complex password to prevent brute-force attacks. The security of WPA2-PSK relies heavily on the secrecy and strength of the pre-shared key. If the key is compromised, the entire network's security is jeopardized. Newer protocols like WPA3 offer enhanced security features, but WPA2-PSK remains a prevalent and effective security measure when implemented correctly.
