A New Efficient and Secure Mutual Authentication Protocol For RFID Systems

Radio Frequency Identification (RFID) is one a promising technology for fast and automatic identification of different objects. This system operates without human intervention; moreover, it processes many simultaneous requests in a very short time span. While RFID applications are increasing, at the same time so are activities regarding their security. Providing the highest level of security and the lowest degree of complexity is the most challenging part in the design and construction of RFID systems. In this paper, we present a new authentication protocol which provides a high degree of security. In addition, it has low complexity and convolution. In this protocol, a public key encryption method was utilized, which is an NP-hard problem, and its possibility of breaking is very weak. The authentication operation is performed at high speed in few steps. Therefore, its implementation is appropriate for mobile devices with limited resources. In terms of security, we analyzed the proposed protocol. The results prove that the proposed protocol is a resilient and robust mechanism against well-known RFID attacks.
