A Decentralized RFID Authentication Solution for Embedded Systems

Radio frequency identification (RFID) and biometric technologies are promising technologies and are already widely used in applications such as building access controls. User authentication is an important mechanism for preventing unauthorized access. Even though we can use different user authentication mechanisms, using single kind of user authentication mechanism may not provide perfect reliable authentication because each of this mechanism has some disadvantages. In this paper, in order to obtain higher degree of security, we propose a decentralized authentication solution for embedded systems that combines both token-based and biometric-based authentication mechanisms. Our proposed solution is implemented and validated. We have obtained results confirming that the proposed solution provides better authentication.
