LLCPS and SISO: A TLS-based framework with RFID for NFC P2P retail transaction processing

The introduction of smartphones enabled with Near Field Communication (NFC) technology facilitates transformation of processes that involve manual intervention such as payment transaction processing in an automated manner. Although payment for transaction using NFC technology is not new, the possibility to use smartphones for payment either through stored payment information in the smartphone or in the cloud allows for seamless integration of associated processes. We consider advances in identification and communication technologies such as RFID (Radio Frequency IDentification) and smartphones as well as the ability to respond in real-time for automated checkout in a retail shopping environment with NFC-enabled smartphones. Using a recently proposed protocol (LLCPS) as an envelope for communication between the smartphone and the NFC reader, we develop a suite of authentication protocols (SISO) for secure payment processing in a retail store environment.
