Discovery and negotiation method for authentication associated kit

Abstract

The invention relates to a finding and negotiation method for authentication related set adapting to ultra wide band. The method comprises: adding pair temporary key establishment IE and group temporary key dispensing IE in IE list of initiator and responser, setting corresponding element ID; 2) finding and negotiation identification of pair temporary key establishment mechanism is supported or not, finding and negotiation identification of group temporary key dispensing mechanism is supported or not; 3) identification of finding and negotiation course of authentication associated set is supported or not; 4) authentication associated course based on finding and negotiation method of authentication associated set. The invention provides a finding and negotiation method adapting to ultra wide band network authentication associated set; the multiple pair temporary key establishment scheme or multiple group temporary key dispensing scheme can provide finding and negotiation function of safe scheme for network, and satisfy all kinds of application demand.

Description

technical field [0001] The invention relates to a method for discovering and negotiating an authentication association suite, in particular to a method for discovering and negotiating an authentication association suite suitable for an ultra-broadband network. Background technique [0002] ECMA (European Computer Manufacturers Association, ECMA) launched the ECMA368 standard in 2005 to define ultra-wideband UWB (Ultra Wideband) physical layer and MAC layer specifications. Ultra-wideband UWB is a carrier-free communication technology that uses nanosecond to microsecond sine wave narrow pulses to transmit data. In the authentication association process of the ECMA368 standard, only a four-way handshake protocol (4-way handshake) and a A group temporary key GTK distribution protocol (Group Temporal Keyexchange) for establishing or updating the group temporary key GTK between ultra-wideband UWB devices. The authentication association process is divided into the following two s...

Problems solved by technology

[0015] It can be seen from the authentication association process of the above two situations: the authentication association process of the ECMA368 standard is based on only one pairwise temporary key PTK establishment scheme (four-step handshake protocol) and only one group temporary key GTK distribution scheme (group temporary key GTK key GTK distribution protocol), if there are multiple pairwise temporary key PTK establishment or group temporary key GTK distribution schemes, the authentication association process of the ECMA368 standard cannot be completed
