NFC TAG AUTHENTICATION: AN OVERVIEW

Near Field Communication (NFC) technology is a short-range wireless communication between two devices that are NFC-enabled. NFC has found application in various institutions like the finance sector, security systems, medicine, etc. Consequently, this has led to a lot of focus on securing NFC transactions. Since most attacks on NFC devices are within the tag, the need to create a more secure tag authentication has increased over the past years. In this paper, I discussed NFC tag authentication and its challenges. Furthermore, I analyzed different existing NFC tag authentication and their respective strengths and weaknesses. The NFChain is better than the existing solutions discussed in this paper. It is cost-friendly, highly secured, and allows extra computation on the tag without requiring additional hardware solutions. In summary, the purpose of this study is to provide insights into NFC tag authentication and the need to conduct more research to ensure more security in this mode of communication.
