Near field communication (NFC) is one of the utmost pullulating technology in the lea of pervasive computing. In the domain of mobile commerce, mobile payments have advantages akin user convenience (anytime and anywhere) enhanced throughout. Several mutual authentication protocols by this time have been schemed to provide security in NFC applications. To guarantee secure communication a conditional privacy preserving security protocol, pseudonym-based NFC protocol and secure and efficient authentication protocol were schemed which could not forfend impersonation attack. In the direction of guaranteeing safe communication a security protocol for NFC-based mobile payments have been proposed. The proposed NFC-based authentication protocol (NAP) describes a simplified authentication process and pawn secure information in mobile commerce transaction. A major concern when using NFC-enabled mobile payment system is user anonymity therefore, users in the mobile payment system are guaranteed their anonymity with the help of pseudonym. The payment transactions are susceptible to variant attacks like replay attack, impersonation attack, man in the middle attack/relay attack and double spending attack thereupon, NAP is the first concern to defend an unauthorized user from retrieving the sensitive payment transaction information.
