Abstract: Radio frectuency identification(RFID) technology has greatly facilitated the supply chain management. The application of secure RFID protocols is one important approach for protecting RFID enabled supply chain system Sc curity requirements for RFID communication protocols in supply chain environments were described. A new secure RFID communication protocol in supply chains was proposed. The new protocol imposes lower computation load and storage cost on RFID tags,and has higher efficiency.

Key words: Supply chain management, Radio frequency identification, Protocol, Attack
