Abstract

This paper gives a comprehensive analysis of security with respect to NFC. We propose a protocol that can be used between an RFID tag and a reader to exchange a secret without performing any expensive computation. The paper introduced an NFC specific key agreement mechanism, which provides cheap and fast secure key agreement. Key agreement techniques without authentication can be used to provide a standard secure channel. This resistance against Man-in-the-Middle attacks makes NFC an ideal method for secure pairing of devices. The paper lists some of threats, which are applicable to NFC, and describes solutions to protect against these threats.
