Method for systematic control by a device for controlling at least one transfer configuration message, the transfer configuration message being a message for configuration of a transfer by direct access from an application (App) being performed on a platform towards a memory zone (M1, M2) used by at least one external material peripheral unit , the platform comprising one or more physical interfaces, the peripheral unit being connected to the platform via one or more physical interfaces of the platform , the peripheral unit using a plurality of memory zones (M1, M2), each memory zone (M1, M2) being characterised by a unique physical address (@P1, @P2), the message for configuration of a transfer comprising at least one field and one body, the field referencing a physical address of a memory zone (M1, M2), the control device belonging to the platform and implementing at least one of the following functions: - a verification function (CHECK), - a synchronisation function (SYNCHRO), - a locking function (FREEZE), - an alert function (ALERT), and - a function for configuration of the control device with a security policy, the method being implemented by the control device and comprising at least the following steps: - providing for the control device a security policy defining the addresses of the memory zones (M1, M2) authorised for the application (App), - providing for the control device a correspondence between the value of a field of the message and a physical address (@P1, @P2) of a memory zone (M1, M2), - providing a structure for controlling transfers in which the configuration message is able to be stored, the structure being used in order to produce data transfers on a first memory zone (M1), respectively on a second memory zone (M2), by direct access to a physical address (@P1) of the first memory zone (M1), respectively to a physical address (@P2) of the second memory zone (M2), referenced in the structure , - receipt of the message by the control device , - conversion by the control device of the body of the message into one or more actions to be effected on a memory zone (M1, M2), and - test by the control device of the conformity of each action with the security policy and issue of a notification when an action is not according to the security policy. - a verification function (CHECK), - a synchronisation function (SYNCHRO), - a locking function (FREEZE), - an alert function (ALERT), and - a function for configuration of the control device with a security policy, - providing for the control device a security policy defining the addresses of the memory zones (M1, M2) authorised for the application (App), - providing for the control device a correspondence between the value of a field of the message and a physical address (@P1, @P2) of a memory zone (M1, M2), - providing a structure for controlling transfers in which the configuration message is able to be stored, the structure being used in order to produce data transfers on a first memory zone (M1), respectively on a second memory zone (M2), by direct access to a physical address (@P1) of the first memory zone (M1), respectively to a physical address (@P2) of the second memory zone (M2), referenced in the structure , - receipt of the message by the control device , - conversion by the control device of the body of the message into one or more actions to be effected on a memory zone (M1, M2), and - test by the control device of the conformity of each action with the security policy and issue of a notification when an action is not according to the security policy. <EOS>
