INTRODUCTION-Relay attack is the most menacing attack that radio frequency identification technology (RFID) systems are facing currently.An attacker could use limited resources to build up this kind of attack with the encryption algorithm which is difficult to detect out.At present, the main methods to resist the relay attack in RFID system include measuring the received signal strength (RSS) between the reader and the tag, the roundtrip time (RTT) of the signal and introducing a second channel -Environmental Conditions.Most of the studies nowadays are adopted the distance bounding protocols which can resist the relay attack by measuring the round-trip time of the short authentication messages between the tag and reader.Many of these protocols have been proposed, such as Hancke and Kuhn's(HK) protocol, Munilla, Ortiz and Peinado's (MOP) protocol and so on.In recent years, researchers have put forward a brand-new solution of using the second channelenvironmental conditions to resist relay attack, such as using button, noise, temperature, etc.This paper mainly does research on the defense techniques for relay attacks in the RFID system and gives some introductions and summaries of the domestic and foreign relevant situation against such attacks.
