Abstract:
A responder authenticity determination system, comprising: a responder that sends a response signal in response to a received signal; an interrogation signal generator that generates an interrogation signal having a random waveform; a transceiver that sends the generated interrogation signal to the responder, and receives a response signal from the responder; and an authenticity determination unit that determines authenticity of the responder based on the received response signal and the random waveform of the generated interrogation signal.
