Development and VLSI implementation of a data security scheme for RFID system using programmable cellular automata

Abstract

Data security is a critical issue for Radio Frequency Identification (RFID) system as it hides important information within it. From both technical and business points of view, it is vital to ensure the security of data for the worldwide use of RFID technology, otherwise hacker or attacker can control the data transmission. So, to secure the RFID tag from ‘hacking’, a data security scheme for RFID tags based on programmable cellular automata has been proposed and implemented in this article. The processor for the system and the secret code generator have been designed in Very High Speed Integrated Circuit Hardware Description Language (VHDL) code using programmable cellular automata (PCA). The processor and ID generator have been simulated in Xilinx ISE 14.3 simulation tools and have implemented the design up to RTL schematic level and the processor has been emulated on the Kintex-7 FPGA board for verification in real environment.
