Abstract: A system includes a first unit associated with an object and a second unit. The first unit includes a first transceiver coupled with first processing circuitry. The second unit includes a second transceiver coupled with second processing circuitry. Methodology includes establishing a bidirectional wireless communication link between the first and second units. Following establishment of the communication link, the first and second units exchange messages. The first processing circuitry measures a first received signal strength indicator (RSSI) value for each of the messages received at the first unit and sends the first RSSI value in a subsequent message to the second unit. The second processing circuitry measures a second RSSI value for each of the messages received at the second unit and sends the second RSSI value in another subsequent message to the first unit. A relay attack is determined in response to the first and second RSSI values.
