Fingerprint-based mutual authentication RFID protocol

Low-cost radio frequency identification (RFID) communication system is exposed to various security and privacy threats. Most of the previous studies focused on prevention techniques to protect RFID communication system from eavesdropping, impersonation and data leakage problems. This paper proposes the use of both prevention and detection techniques to improve and solve the security issues. A mutual authentication protocol with integration of tag's unique power response is proposed to enhance the security level in RFID communication. The received power of tag is used as a unique electronic fingerprint to detect cloning tags. A lightweight cryptographic algorithm that conforms to the EPCglobal Class-1 Generation-2 standard is used to prevent replay attack, denial of service, and data leakage issues.
