Patent ID: 8625801

Claim:
A method for discovering and negotiating about an authentication and association suite, comprising: dependent upon an authentication and association process in the method for discovering and negotiating about an authentication and association suite, when an initiating device and a responding device are required to discover and negotiate about an authentication and association suite, performing passive scanning in which the responding device waits for reception of information of a beacon frame transmitted from the initiating device and transmits to the initiating device a probe request frame after reception of the information of the beacon frame or active scanning in which the responding device transmits to the initiating device a probe request frame requesting for relevant information; and during the passive scanning or the active scanning, the responding device adding, in a list of Information Elements (IEs) of a probe request frame transmitted to the initiating device, a full field of Pairwise Temporal Key (PTK) Creation mechanism IE or Group Temporal Key (GTK) Distribution mechanism IE to declare a list of responding device supportable mechanisms for creating a PTK or mechanisms for distributing a GTK; and the initiating device constructing and transmitting to the responding device a probe response frame according to the contents of the full field of PTK Creation mechanism IE or GTK Distribution mechanism IE in a received probe request frame by adding, in a list of IEs of the probe response frame, a full field of PTK Creation mechanism IE or GTK Distribution mechanism IE to declare an initiating device selected mechanism for creating a PTK or mechanism for distributing a GTK.
