Advanced real time RFID mutual authentication protocol using dynamically updated secret value through encryption and decryption process

Abstract

Radio Frequency Identification (RFID) Technology is growing popular in wireless communications. It can be used easily for security purposes using authentication protocol. In the literature, researchers proposed different types of RFID based authentication protocols to ensure security and privacy. RFID technology is used in IoT (Internet of things) for real time authentication like access control in offices, homeland security, and transportation and also in defense and sensitive medical organizations. In this paper we proposed a hash based mutual authentication protocol that can dynamically update secret key value between tag and the reader. This protocol is secure and immune to different kinds of attacks.
