Enhancing Contactless Transaction Security: A Lightweight Authentication Approach

The increasing adoption of contactless transactions has introduced new security challenges, particularly in protecting data from unauthorized access and fraudulent activities. This study presents a novel authentication framework designed to enhance the security of near-field communication (NFC) transactions while maintaining efficiency for real-time processing. By leveraging a lightweight cryptographic approach, the proposed system mitigates threats such as relay attacks and unauthorized skimming. Experimental analysis demonstrates improvements in authentication reliability and resistance to common attack vectors. This research contributes to the development of more secure and scalable contactless payment solutions.
