In wireless security, PSK stands for what?

• A. Public Shared Key
• B. Private Secure Key
• C. Pre-Shared Key (PSK)
• D. Post-Shared Key

Answer: (C)

PSK stands for Pre-Shared Key. This is a secret that’s configured in advance on both the Wi‑Fi access point and all client devices. When a device connects, the shared key is used to derive the encryption keys for the session through the handshake, enabling secure communication without assigning individual user credentials. This setup is common in WPA-PSK/WPA2-PSK for smaller networks. The strength hinges on using a long, complex passphrase, since an attacker could try offline guessing if the passphrase is weak. It differs from enterprise networks that use per-user credentials managed by an authentication server. The other terms listed aren’t standard in wireless security.
