Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. An apparatus comprising:
means for challenging vehicles to test their authenticity, the means for challenging to:
cause a first transmission of a first challenge packet at a first frequency, the first challenge packet to instruct a first electronic system to transmit a first challenge response at a second frequency, the first frequency and the second frequency based on a first frequency band hopping pattern;
cause a second transmission of a second challenge packet at a third frequency, the second challenge packet to instruct a second electronic system to transmit a second challenge response at a fourth frequency, the third frequency and the fourth frequency based on a second frequency band hopping pattern;
increase a counter corresponding to the first electronic system after not obtaining the first challenge response; and

means for causing transmission of a third transmission of a data packet to a third electronic system, the third transmission to cause the third electronic system to drop at least one future message from the first electronic system in response to a determination that the counter satisfies a threshold.
