Abstract
The systems, methods and apparatuses described herein provide an apparatus configured for preventing relay attacks on a communication link between the apparatus and a communication partner. The apparatus may comprise a communication port, a timer and a processor. The processor may be configured to generate a request, transmit the request through the communication link using the communication port and start counting time using the timer, receive a response via the communication port and stop the timer, receive authentication data via the communication port, authenticate the authentication data, compare the counted time with a predefined threshold, compare a first field within the request with a second field within the response and determine whether there is a relay attack.
