Title (EN) METHODS AND APPARATUS FOR DERIVING, COMMUNICATING AND/OR VERIFYING OWNERSHIP OF EXPRESSIONS
(FR) PROCÉDÉS ET APPAREIL POUR DÉDUIRE, COMMUNIQUER ET/OU VÉRIFIER LA POSSESSION D'EXPRESSION
Abstract: front page image
(EN)Methods and apparatus for generating, communicating, and/or verifying ownership of expressions are described. Various embodiments are well suited for use in a wireless peer to peer communications systems in which expressions are communicated, e.g., broadcast, in discovery intervals. A first communications device generates an expression from a first public key and an additional input, said first public key corresponding to a private key known to said first communications device. The first device transmits the generated expression on a communications channel used for discovery. A second communications device receives the transmitted expression from the first device. The second device transmits a request signal to the first device associated with the expression; and receives from the first device a signed communication signed using a private key known to said first communications device. The second device uses information from the signed communication to determine if said first communication device owns said expression.
(FR)La présente invention concerne des procédés et un appareil servant à générer, communiquer et/ou vérifier la possession d'expressions. Divers modes de réalisation conviennent parfaitement pour une utilisation dans des systèmes de communication pair à pair sans fil dans lesquels des expressions sont communiquées, par exemple diffusées, à des intervalles de découverte. Un premier dispositif de communications génère une expression à partir d'une première clé publique et d'une entrée supplémentaire, ladite première clé publique correspondant à une clé privée connue dudit premier dispositif de communications. Le premier dispositif transmet l'expression générée sur un canal de communications utilisé pour la découverte. Un second dispositif de communications reçoit l'expression transmise par le premier dispositif. Le second dispositif transmet un signal de demande au premier dispositif associé avec l'expression, et reçoit du premier dispositif une communication signée à l'aide d'une clé privée connue dudit premier dispositif de communications. Le second dispositif utilise des informations de la communication signée pour déterminer si ledit premier dispositif de communications possède ladite expression.
