Systems and methods of performing link setup and authentication

An apparatus comprising:

• a processor;
• and
• a memory storing instructions executable by the processor to:
• send a request to an access point, wherein the request includes a station nonce (SNonce) associated with a mobile device and an Extensible Authentication Protocol (EAP)-re-authentication-Initiate message, wherein the EAP-re-authentication-Initiate message is included in a first information element of the request and the SNonce is included in a second information element of the request, the first information element distinct from the second information element;
• receive a response from the access point in response to the request, wherein the response includes:
• an authentication parameter based on the EAP-re-authentication-Initiate message,
• and
• an access point nonce (ANonce) that was generated after the request was sent;
• and
• generate a pairwise transient key (PTK) using the SNonce and the ANonce that was received in the response.

• means for generating, at the mobile device, a pairwise transient key (PTK) using the SNonce and the ANonce that was received in the response.
