Rapdos: A RFID Authentication Protocol for Defending against DoS

Radio frequency identification (RFID) technology is a non-contact automatic identification technology. The basic principle of RFID is coupled with radio frequency signal and the spatial transmission characteristics. From object recognition to achieve automatic recognition, RFID has the advantages of being effective, diversity, high capacity, low cost, anti-pollution, penetrating and so on. However, current RFID authentication protocols cannot defend against DoS attack. This paper proposes Rapdos, a novel mutual authentication protocol, which is based on the use of symmetric encryption and dynamic update key to prevent the DoS attack. The experiment has validated that Rapdos has provided good security for RFID system, and can defeat location privacy attack, relay attack, eavesdropping attack, denial-of-service attack, and solve problems of RFID security privacy.
