Title (EN) METHOD FOR AUTHENTICATING THE RESULT OF AN INSTRUCTION IN A TOKEN
(FR) PROCEDE D'AUTHENTIFICATION DU RESULTAT D'UNE COMMANDE DANS UN JETON
Abstract:
(EN) The invention relates to a method for authenticating a result of the execution of an instruction in a token which is connected to a terminal, said terminal comprising a device for communicating information to a user of the token and said token transmitting a result to the terminal when the instruction has been executed. The invention is characterised in that the method comprises the following steps: checking whether the instruction has a sensitive character and if the instruction does have a sensitive character, carrying out the following steps; inputting digitizable information using an interface which comprises an inputting device that is linked to said token, for each sensitive potential result of the instruction, and transmitting said digitizable information to said token; executing the instruction; transmitting a response from the token to the terminal, said response containing the associated digitizable information for a sensitive result, this digitizable information being associated with said result; and if the result is sensitive, checking that the response actually contains the input information using the communications device of said terminal.
(FR) L'invention concerne un procédé d'authentification d'un résultat d'exécution de commande dans un jeton connecté à un terminal, ledit terminal comportant un dispositif de communication d'une information à un utilisateur dudit jeton, ledit jeton transmettant un résultat au terminal suite à ladite exécution. L'invention se caractérise en ce que ledit procédé comporte les étapes selon lesquelles: on vérifie si la commande comporte un caractère sensible, si la commande comporte un caractère sensible, on effectue les étapes selon lesquelles: pour tout résultat potential sensible de la commande, on saisit une information numérisable au moyen d'une interface comportant un dispositif de saisie reliée audit jeton, et on transmet audit jeton ladite information numérisable, on exécute ladite commande, on transmet dudit jeton au terminal une réponse comportant, pour un résultat sensible, ladite information numérisable associée audit résultat, si le résultat est sensible, on vérifie au moyen du dispositif de communication dudit terminal que ladite réponse comporte effectivement ladite information numérisable saisie.
