Security Problems in an RFID System

This paper focuses on the security and privacy threats being faced by the low-cost RFID communication system, the most challenging of which relate to eavesdropping, impersonation, and tag cloning problems. The security issues can be improved and solved by utilizing both prevention and detection strategies. Prevention technique is needed since it offers resistance capabilities toward eavesdroppers and impersonators. Detection technique is vital to minimize the negative effects of tag cloning threats. This paper proposes the use of both prevention and detection techniques to make RFID communication more secure. Lightweight cryptographic algorithm, which conforms to the EPC Class-1 Generation-2 standard, is used in the proposed mutual authentication protocol for RFID system to raise security levels. In addition, electronic fingerprinting system is deployed in the proposed solution as a detection method to distinguish counterfeit and legitimate tags.
