Abstract
The application relates to a 4-way handshake optimization. An initiating entity includes processor circuitry configured to: transmit a first open authentication frame to a responding entity via a wireless interface, wherein the first open authentication frame comprises information that helps the responding entity to identify a Pairwise Master Key (PMK) and a first random number; receive a second open authentication frame from the responding entity, wherein the second open authentication frame comprises a second random number; transmit an association request frame to the responding entity via the wireless interface, wherein the association request frame is encrypted with at least part of a Pairwise Transient Key (PTK) derived by the initiating entity from the PMK; and receive an association response frame from the responding entity, wherein the association response frame is encrypted with at least part of the PTK derived by the responding entity from the PMK.
