[Abstract]:Radio Frequency Identification (RFID) technology has been widely used in many aspects of social life. However, its security threats and privacy issues have attracted more and more attention. In recent years, the security of various encryption algorithms suitable for RFID tags has also become a research hotspot. In this paper, the research status of elliptic curve encryption algorithm used in RFID system is analyzed, the principle of elliptic curve encryption algorithm is described, and an Elliptic Curve Cryptograph (ECC) processor is designed for RFID tag. The security tag chip is tested by FPGA. In the algorithm layer, the influence of ECC system parameters on security and implementation cost is analyzed, and the 163-bit elliptic curve in the binary extended field in projection coordinate system is determined. Various algorithms for implementing ECC point multiplication are analyzed and studied. Lopez-Dahab algorithm, which is the most suitable for RFID tag area and power consumption requirements, is selected, and various problems in the implementation of this algorithm are studied and solved. In the aspect of circuit design, special arithmetic logic unit is designed to realize addition, square and multiplication on finite field, and the optimization is carried out respectively. Finally, in order to verify the correctness and performance of the ECC processor designed in this paper, the functions of each arithmetic unit in the circuit are verified. FPGA is used to verify the function, and the ASIC implementation of the whole tag chip is completed in SMIC0.13 process. The chip area is 0.4 脳 0.4mmm2, and the power consumption is 20 渭 A. The verification results show that the ECC processor fully meets the RFID tag power consumption, area and timing requirements, and achieves the desired goal.
