Enhancing Security for NFC- A Survey

Abstract

Near field communication (NFC) is short range wireless communication technology based on radio frequency identification (RFID). It uses magnetic field to enable communication between devices. To apply NFC in electronic payment, security is a requirement to be addressed. Currently, NFC security standards define data exchange format, security protocols, tag types, and cantering on NFC forum. It is specifically fixed in the NFC security standards that key agreement is required for secret connections between users. In the procedure of key agreement, both users should swap their public keys. Malicious internal attackers can create profiles of users through the gaining of public keys of other users in the process of key agreement. If NFC is used in e-payment in this way, the privacy of users can be infringed through profiles created by attackers. Solution on these threats is to create a secure channel. In secure channel a standard key agreement protocol could be applied to establish a shared secret between two devices. Beside the standard key agreement mechanism, it is also likely to implement an NFC specific key agreement.
