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, respectively on a second memory zone, by direct access to a physical address (@P1) of the first memory zone, respectively to a physical address (@P2) of the second memory zone, 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, respectively on a second memory zone, by direct access to a physical address (@P1) of the first memory zone, respectively to a physical address (@P2) of the second memory zone, 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.
