Abstract
(EN)
A method for transmitting and receiving a secure message. Transmission is by generating, using a device identifier (408), an application identifier (406) and an application value (412), of a message value (502), combining the message value (502) with one or more first secret values (400), said secret values (400) being known substantially only to the originating device and one or more intended recipient devices of the message, to establish a secret message value (506), applying the secret message value (506) and the message to an encoding process (602) to form a secure message block (604), and combining an address (616, 618) with a device identifier (408), the application identifier (406), the application value (412) and the secure message block (604), to form a secure message (606) for transmission which is decodable by the one or more of said intended recipient devices which thereby recover the message, the address, the device identifier, the application identifier and the application value.

Cette invention se rapporte à un procédé de transmission et de réception de messages sécurisés. On réalise la transmission des messages en générant, à l'aide d'un identificateur de dispositif (408), d'un identificateur d'application (406) et d'une valeur d'application (412), une valeur de message (502), en combinant cette valeur de message (502) avec une ou plusieurs premières valeurs secrètes (400), lesquelles ne sont connues essentiellement que par le dispositif expéditeur et par un ou plusieurs dispositifs destinataires voulus du message, afin d'établir une valeur de message secrète (506), en appliquant cette valeur de message secrète (506) et le message à un processus de codage (602), pour former un bloc de message sécurisé (604), et en combinant une adresse (616, 618) avec un identificateur de dispositif (408), avec l'identificateur d'application (406), avec la valeur d'application (412) et avec le bloc de message sécurisé (604), afin de former un message sécurisé (606) destiné à être transmis, qui est décodable par le ou les dispositifs destinataires voulus, lesquels récupèrent ainsi le message, l'adresse, l'identificateur de dispositif, l'identificateur d'application et la valeur d'application.
