Abstract

The existing protocol defined in the ISO/IEC 18000-3 standard does not include the cryptographic authentication mechanism. To remove security vulnerabilities, this paper proposes a strong authentication protocol for RFID tag using SHA-1 hash algorithm. The protocol is based on a three-way challenge response authentication protocol between the tags and a back-end server. In addition, three types of the protocol packets are extended for realizing a strong authentication mechanism, which modifies the protocol defined in the ISO/IEC standard. In order to verify the proposed scheme, a digital Codec is described in Verilog HDL, and simulated using extended three packets as input vectors. The system operates at a clock frequency of 75 MHz on Xilinx FPGA device. From comparison and implementation results, we will show that our scheme is a well-designed strong protocol that satisfies various security requirements in RFID system environment.
