ARM and FPGA Implementation of Secured Authentication Protocol for RFID System

S.Mohanavelu, T.Ramya

The authentication process of RFID tag's the tag/reader/server communicates over an insecure channel due to weak authentication protocols. The Electronic Product Code (EPC) Class-1 Generation-2 (C1G2) specification have some serious security problems, so the password either leak directly over the network or leaks the sufficient information i.e., while performing authentication, that allow hackers to deduce or guess the password. To overcome this weak authentication a specially designed pad generation (Pad Gen) function is used to improve security. The Pad Gen function is used to produce a cover-coding pad to mask the tag's access password before the data transmission. Hence a mutual authentication protocol with XOR scheme and MOD Scheme is proposed to avoid the data leakage and data traceability during the data transmission .This system model is simulated and synthesized using Xilinx ISE software. The performance of this authentication scheme will be verified in hardware using ARM 7 and Spartan 3E FPGA.
