  2. Phase-shift keying - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_keying

    Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency carrier wave. The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and Bluetooth communication.

  3. Pre-shared key - Wikipedia

    en.wikipedia.org/wiki/Pre-shared_key

    In cryptography, a pre-shared key (PSK) is a shared secret which was previously shared between the two parties using some secure channel before it needs to be used. [ 1 ] Key

    en.wikipedia.org/wiki/IEEE_802.11i-2004

    The four-way handshake [8] is designed so that the access point (or authenticator) and wireless client (or supplicant) can independently prove to each other that they know the PSK/PMK, without ever disclosing the key. Instead of disclosing the key, the access point (AP) and client encrypt messages to each other—that can only be decrypted by ...

  5. Continuous phase modulation - Wikipedia

    en.wikipedia.org/wiki/Continuous_phase_modulation

    Continuous phase modulation (CPM) is a method for modulation of data commonly used in wireless modems.In contrast to other coherent digital phase modulation techniques where the carrier phase abruptly resets to zero at the start of every symbol (e.g. M-PSK), with CPM the carrier phase is modulated in a continuous manner.

    Although it was allegedly designed to operate on top of Wi-Fi, compatibility with the security protocol used by the 802.11 wireless networking standard developed by the IEEE is in dispute. Due to the limited access of the standard (only eleven Chinese companies had access), it was the focus of a U.S.–China trade dispute .

  7. Extensible Authentication Protocol - Wikipedia

    The Lightweight Extensible Authentication Protocol (LEAP) method was developed by Cisco Systems prior to the IEEE ratification of the 802.11i security standard. [3] Cisco distributed the protocol through the CCX (Cisco Certified Extensions) as part of getting 802.1X and dynamic WEP adoption into the industry in the absence of a standard.

  9. Differential coding - Wikipedia

    en.wikipedia.org/wiki/Differential_coding

    In digital communications, differential coding is a technique used to provide unambiguous signal reception when using some types of modulation.It makes transmissible data dependent on both the current and previous signal (or symbol) states.
