Claim 20:
21. A system comprising:
a server to transmit a first challenge packet at a first frequency to a first electronic system, the first challenge packet to instruct the first electronic system to transmit a first challenge response at a second frequency to the server, the first frequency and the second frequency based on a first frequency band hopping pattern;
a trusted vehicle to transmit a second challenge packet at a third frequency to a second electronic system, the second challenge packet to instruct the second electronic system to transmit a second challenge response at a fourth frequency to the trusted vehicle, the third frequency and the fourth frequency based on a second frequency band hopping pattern; and
the server to:
increment a first counter corresponding to the first electronic system after the server does not obtain the first challenge response;
increment a second counter, the second counter corresponding to the second electronic system after the trusted vehicle does not obtain the second challenge response; and
after a determination that at least one of the first counter or the second counter satisfies a threshold, instruct the trusted vehicle to drop a future message from a respective one of the first electronic system or the second electronic system that corresponds to the at least one of the first counter or the second counter that satisfies the threshold.
