A mechanism in Wi-Fi Protected Access (WPA)-Personal that allows the use of manually entered keys or passwords to initiate WPA security. The PSK is entered on the access point or home wireless gateway and each PC that is on the Wi-Fi network. After entering the password, Wi-Fi Protected Access automatically takes over. It keeps out eavesdroppers and other unauthorized users by requiring all devices to have the matching password. The password also initiates the encryption process which, in WPA is Temporal Key Integrity Protocol (TKIP) and in WPA2 is Advanced Encryption Standard (WPA2). (See TKIP, WPA-Personal, WPA2-Personal). close
Pre Shared Key. A single passphrase / key used for authentication with WPA and WPA2.
Phase-Shift Key - It's a form of phase modulation for digital signals, where the bits are quantified by various phase changes. It involves changing the phase of transmitted waveform instead of the frequency, these finite phase changes representing digital data. In its simplest form, a phase-modulated waveform can be generated by using the digital data to switch between two signals of equal frequency but opposing phase.
A modulation technique for transmitting digital information to analog whereby that information is conveyed as varying phases of a carrier signal.
