CA 2660288

A sending device prepares a key for each electronic message sent by the device by applying an algorithm to specified data in the message and then incorporates the key in the message. A receiving device, upon receipt of an electronic message, locates the incorporated key and the data from which a sending device practicing the invention would have prepared it. The receiving device communicates a confirmation request to the purported sending device which contains the key and the data for its preparation. The sending device receives the confirmation messages and prepares a comparison key by applying the algorithm to the data in the confirmation request. The sending device replies to the confirmation request confirming that the sending device sent the message if the comparison key matches the key in the confirmation request and otherwise responds with a denial.

Selon le système de l~invention, un dispositif émetteur prépare une clé pour chaque message électronique envoyé par le dispositif en appliquant un algorithme à des données spécifiées dans le message et incorpore la clé dans le message. Un dispositif récepteur, sur réception du message électronique, repère la clé incorporée et les données à partir desquelles un dispositif émetteur exploitant l~invention l~aurait préparée. Le dispositif récepteur communique une requête de confirmation au dispositif émetteur supposé, qui contient la clé et les données pour sa préparation. Le dispositif émetteur reçoit les messages de confirmation et prépare une clé de comparaison en appliquant l~algorithme aux données de la requête de confirmation. Le dispositif émetteur répond à la requête de confirmation en confirmant que le dispositif émetteur a envoyé le message si la clé de comparaison correspond à la clé dans la requête de confirmation et répond sinon par la négative.
