An Gen2 Based Security Authentication Protocol for RFID System

Abstract EPC Class-1 Generation-2 specification(Gen2 in brief) has been accepted as the standard for RFID tags under grant number ISO18000-6C. However, Gen2 does not pay due attention to security. For this reason, a Gen2 based security authentication protocol is developed in this paper. In details, we study the security requirements presented in the current Gen2 based RFID authentication protocols [7] , [8] , [9] , [10] , [11] , [12] , [13] . Then we point out the security flaws of Chien's mutual authentication protocol [7] , and improve the protocol based on a 11 security requirements. Our improved protocol merely uses CRC and PRNG operations supported by Gen2 and meets the 11 security requirements. In contrast to the similar work [14] , [15] on Chien's protocol or other Gen2 based schemes, our protocol is more secure and our security analysis is much more comprehensive and qualitative.
