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 9):
The method as claimed in  claim 4 , wherein there is performed an initial step of learning of the defense housing with respect to the activation module present in a specific automotive vehicle, this initial step consisting in placing within range of emission of the activation module the defense housing in a mode of detection of frames of electromagnetic waves without at least partial destruction of the intercepted frames, in making the activation module emit an emitted frame of electromagnetic waves specific to this activation module, in making the defense housing recognize this emitted frame of electromagnetic waves as being specific to the activation module and in making the defense housing store at least the start of this emitted frame of electromagnetic waves and, when the defense housing is placed out of range of emission of the activation module, the at least partial destruction of an intercepted frame of electromagnetic waves at said at least one activation means and/or of a response frame of electromagnetic waves of said at least one activation means toward the activation module is effected after comparison and similarity of the stored start of the frame of electromagnetic waves emitted by the activation module with a start of the intercepted frame.
