Abstract:
A method of defense against an attack relay action on a remote activation of a function present in an automotive vehicle. The attack relay receives a frame of electromagnetic waves emitted by the activation module and retransmits it to the at least one activation device, nevertheless out of range of emission of the activation module, which dispatches a response frame of electromagnetic waves to the activation module. There is performed, out of range of emission of the activation module, an at least partial interception of a retransmitted frame of electromagnetic waves originating from the attack relay in the direction of the activation device. An at least partial destruction of the retransmitted frame at the activation device and/or of the response frame of the activation device toward the activation module rendering the activation of the function inoperative is performed.

Claim (Index 1):
A method of defense against an attack relay action on a remote activation of a function present in an automotive vehicle, the activation being effected between at least one activation means belonging to a person entitled to operate this activation and an activation module present in the vehicle by emission and reception of electromagnetic waves between said at least one activation means and the activation module, the attack relay action comprising receiving a frame of electromagnetic waves emitted by the activation module and retransmitting it to said at least one activation means then being in a zone out of range of emission of the activation module, said at least one activation means, after reception of a frame of electromagnetic waves retransmitted by the attack relay, then re-emitting a response frame of electromagnetic waves toward the activation module for the activation of the function, the method comprising:\n performing by a defense housing, in a zone out of range of emission of the activation module, an at least partial interception of the frame of electromagnetic waves retransmitted from the attack relay in the direction of said at least one activation means, an at least partial destruction of the frame of electromagnetic waves retransmitted to said at least one activation means and/or of the response frame of electromagnetic waves of said at least one activation means toward the activation module, this destruction rendering the activation of the function inoperative, and performing at every start of the defense method, a verification of a positioning of the defense housing out of range of the activation module, the defense housing being rendered inoperative when present in one of the detection zones in proximity to the vehicle.
