Abstract
(EN)
An apparatus and method establish a secure, direct, station-to-station communication between a first station and a second station in a topology (e.g., PBSS) having a central secret holder/provider that allows secure, direct, station-to-station communications and that allows secure station-to-station broadcast communications. The first station and the second station will have previously established a security association (SA) with a topology control point (PCP). The method includes creating pair-wise unique material for the first station. The pair-wise unique material is computed as a function of (i) a known shared secret associated with the PCP, (ii) a first piece of unique data associated with the first station, and (iii) a second piece of unique data associated with the second station. The method includes securely communicating the pair-wise unique material from the first station to the second station.
(FR)
L'invention porte sur un appareil et un procédé établissant une communication sécurisée directe de station à station entre une première station et une seconde station dans une topologie (par exemple, PBSS) comportant un détenteur/fournisseur standard de secret standard permettant des communications sécurisées directes de station à station et permettant des communications sécurisées de diffusion de station à station. La première station et la seconde station auront précédemment établi une association de sécurité (SA) avec un point de commande de topologie (PCP). Le procédé comprend la création d'un matériel unique par paire pour la première station. Le matériel unique par paire est calculé en fonction de (i) un secret partagé connu associé au PCP, (ii) un premier élément de données particulières associé à la première station et (iii) un second élément de données particulières associées à la seconde station. Le procédé comprend la communication sécurisée du matériel unique par paire de la première station et la seconde station.
