PSK
Phase-based digital encoding
PSK is an abbreviation with several technical meanings.
In telecommunications, it stands for phase-shift keying, a method of transmitting digital signals by varying the phase of a carrier wave.
In security contexts, PSK means pre-shared key—a password or passphrase shared between parties before establishing an encrypted connection: The router uses WPA2-PSK encryption.
