A Study for the Convictional Authentication of EPC Global Class-1 Generation-2

Epcglobal class-1 generation-2 has been approved by the ISO18000-6C for the global usage. Here the tag can be traceable and that is transmitted into the plain text . In traditional encryption methods we use symmetric or asymmetric ciphers but this encryption methods are not suitable for the RFID tags. Gen2 has proposed some lightweight authentication protocols. Here message flow in RFID tag is different from other earlier techniques. There are many reasons why the existing tag readers fails to read the updated tags and new tags. To overcome this problems based on Gen2 protocol a novel authentication protocol has been proposed called for low cost RFID tags. For every message flow there is a backward compatibility. To achieve reader to tag authentication a multiple round protocol using shared pseudonyms are data errors are used here. Memory read command is used to achieve tag-to-reader authentication in Gen2ф which is defined in Gen2. Gen2ф is more secure under tracing and cloning attacks.
