Authentication associated suite discovery and negotiation method
First Claim
1. 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.

Abstract
An authentication associated suite discovery and negotiation method for ultra wide band network. The method includes the following steps of: 1) adding a pairwise temporal key PTK establishment IE and a group temporal key GTK distribution IE in an information element IE list of an initiator and a responder, and setting a corresponding information element identifier ID, and 2) an authentication associated process based on the authentication associated suite discovery and negotiation method. The authentication associated suite discovery and negotiation method for ultra wide band network provided by the present invention can provide the discovery and negotiation functions of a security solution to the network so as to satisfy all kinds of application requirements better when multiple pairwise temporal key PTK establishing plans or multiple group temporal key GTK distributing plans co-exist.
