Abstract: Many of the existing protocols for radio frequency identification (RFID) either do not conform to the EPC Class-1 Gen-2 (EPCGen2) standards or suffer from security flaws. Safety requirements for RF)D protocols were discussed and recently proposed EPCGen2 compliant cryptographic protocols were analyzed, and the design principles of EPCGen2 compliant authentication protocols were given. A new RFID authentication protocol based on the EPCGen2 standards was also proposed. The new protocol provides mutual authentication, anonymity, untraceability, anti-imper-sonation attack and anti-replay attack.

Key words: Radio frectuency identification, Authentication protocol, Attack, Security
