Abstract

A wireless access method includes the following steps. An access point obtains a personal identification number of a terminal device and broadcasts a beacon. The access point performs a terminal device authentication on a vendor specific information element of a probe request from the terminal device according to the personal identification number. When the terminal device authentication is successful, the access point performs a key calculation according to the personal identification number and the probe request to generate a pairwise transient key, a key encryption key and a group transient key and uses the key encryption key to encrypt a pre-shared key and the group transient key. The access point transmits a probe response to the terminal device. The access point installs the pairwise transient key and the group transient key to establish an encrypted transmission.

Dependent claims

A wireless access method, comprising:

(a) obtaining, by an access point, a personal identification number of a terminal device and broadcasting, by the access point, a beacon comprising a first vendor specific information element;
(b) receiving, by the access point, a probe request from the terminal device comprising a second vendor specific information element and performing, by the access point, a terminal device authentication on the second vendor specific information element according to the personal identification number;
(c) when the terminal device authentication is successful, performing, by the access point, a key calculation according to the personal identification number and the probe request to generate a pairwise transient key, a key encryption key, and a group transient key and encrypting, by the access point, a pre-shared key and the group transient key of the access point by using the key encryption key to generate an encrypted pre-shared key and an encrypted group transient key;
(d) transmitting, by the access point, a probe response comprising a third vendor specific information element to the terminal device, wherein the third vendor specific information element comprises the encrypted pre-shared key and the encrypted group transient key;
and
(e) installing, by the access point, the pairwise transient key and the group transient key to establish an encrypted transmission.
