  • Method and system for securing data transmitted by a connected object against attacks affecting a control circuit of said object
    Patent number: 11165633
    Abstract: The present invention concerns a method for securing data transmitted by a data source (2) of a connected object (1) against attacks affecting a control circuit (4) of the connected object (1), the connected object (1) also comprising an electronic signature circuit (6) and a communication bus (8) connected to the control circuit (4), connected to the electronic signature circuit (6) and connected to the source (2), wherein the method comprises the following steps implemented by the electronic signature circuit (6): detecting (602) a first datum (M) transmitted by the source (2) on the communication bus (8); detecting (606) a second datum (M?) to be signed, on the communication bus, the second datum having been transmitted (404) by the control circuit (4) on the communication bus (8) after detection of the first datum (M) by the control device (4); verifying (608) coherence between the detected data (M, M?), signalling (610) an error (E), if any, as a function of a result of the verification.
