Claim Text:
1. A method comprising: sending a request from a mobile device to an access point, wherein the request includes a station nonce (SNonce) associated with the 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; receiving 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 generating, at the mobile device, a pairwise transient key (PTK) using the SNonce and the ANonce that was received in the response.
