Abstract
Apparatus, systems, and methods send an interrogation command from an interrogation and timing apparatus to a timed identification (TID) apparatus. The TID apparatus receives the interrogation command, performs a series of logical operations to calculate a response, and returns the response within a maximum length of time established by the interrogation and timing apparatus. The interrogation and timing apparatus confirms that the length of time between sending the interrogation command and receiving the response is within the maximum length of time and that the response is correct. If so, the TID apparatus is authenticated. Additional embodiments are disclosed and claimed.
