Abstract
Near Field Communication (NFC) is an attractive technology which is used in several countries for contactless payment operations via mobiles. This technology is suffered from increasing the security weaknesses. In the NFC mobile payment systems, the payment operations are vulnerable to various attacks. Therefore, the authentication protocol in the NFC technology has the highest priority to develop such systems. This paper proposes a new secure authentication protocol to provide strong security features for the NFC mobile payment systems, called (SAP-NFC) protocol. Compared with the recent NFC mobile payment authentication protocols, the security analysis has illustrated that the proposed SAP-NFC protocol can achieve highest level of security by supporting the fully mutual authentication, the key forward/backward secrecy, anonymity and untraceability features. In addition to, the SAP-NFC protocol is secure against replay attack, impersonate attack, tracking attack and desynchronization attack.
