Title
(EN) METHOD AND DEVICE FOR COVERTLY COMMUNICATING STATE CHANGES
(FR) PROCÉDÉ ET DISPOSITIF POUR COMMUNIQUER DE MANIÈRE DISSIMULÉE DES CHANGEMENTS D'ÉTAT
Abstract
(EN) Disclosed herein is a device configured to covertly communicate state information within a transmitter address field of a message. The device comprises a memory configured to store a state key and state information of the device, and a controller in communication with the memory. The controller is configured to apply a one-way function, using the state key, to the state information to produce a transmitter address, and transmit the message, including the transmitter address in the transmitter address field of the message.
(FR) Un dispositif, configuré pour communiquer de manière dissimulée des informations d'état dans un champ d'adresse d'émetteur d'un message, est divulgué ici. Le dispositif comprend une mémoire configurée pour stocker une clé d'état et des informations d'état du dispositif, et un dispositif de commande en communication avec la mémoire. Le dispositif de commande est configuré pour appliquer une fonction unidirectionnelle, au moyen de la clé d'état, aux informations d'état afin de produire une adresse d'émetteur, et transmettre le message, comprenant l'adresse d'émetteur dans le champ d'adresse d'émetteur du message.
