To handle the updating, 802.11i defines a Group Key Handshake that consists of a two-way handshake: The AP sends the new GTK to each STA in the network. The GTK is encrypted using the KEK assigned to that STA, and protects the data from tampering, by use of a MIC. The STA acknowledges the new GTK and replies to the AP.
Included in the retail box are an SD card, desk stand, handle for putting the H2 in a microphone stand, wind screen, 3.5mm TRS to RCA cable, earbud headphones, USB cable and power adapter. The H2's microphones, functionality, and use of standard USB and SD interfaces make it suitable both for recording high-quality sound and in many speech ...
Initially, devices associate with the Access Point (AP) via an association request. This is followed by a 4-way handshake, a crucial step ensuring both the client and AP have the correct Pre-Shared Key (PSK) without actually transmitting it. During this handshake, a Pairwise Transient Key (PTK) is generated for secure data exchange. [12]
Handshaking is a technique of communication between two entities. However, within TCP/IP RFCs, the term "handshake" is most commonly used to reference the TCP three-way handshake. For example, the term "handshake" is not present in RFCs covering FTP or SMTP. One exception is Transport Layer Security, TLS, setup, FTP RFC 4217.
Devices utilizing 802.11 based standards can enjoy the benefits of collision avoidance (RTS / CTS handshake, also Point coordination function), although they do not do so by default. By default they use a Carrier sensing mechanism called exponential backoff (or Distributed coordination function ), that relies upon a station attempting to ...
IEEE 802.11r-2008 or fast BSS transition (FT), is an amendment to the IEEE 802.11 standard to permit continuous connectivity aboard wireless devices in motion, with fast and secure client transitions from one Basic Service Set (abbreviated BSS, and also known as a base station or more colloquially, an access point) to another performed in a nearly seamless manner.
