Advance Strong Authentication Strong Integrity (ASASI) Protocol for Low Cost Radio Frequency Identification

Internet of things is one of the emerging concepts in 5G networks. For global connectivity and basic identification of the wireless nodes, the RFID system plays an important role. The RFID systems provide automatic identification of the wireless nodes without the restriction of line of sight. However, security and privacy of the RFID systems are of utmost concern. Many ultralightweight authentication schemes have been proposed for secure communication between the reader and the tag. However, most of them were reported to be vulnerable against various attacks shortly after they were proposed. In this paper, we addressed this research gap and propose a new ultralightweight RFID authentication protocol ASASI (Advance Strong Authentication and Strong Integrity). The proposed protocol is extremely lightweight due to optimized design structure and can withstand against all existing attack models.
