Abstract: This paper introduces several typical methods to against security and privacy problems, and aim at the shortages in them and other improved ones which provided by some literatures, proposes a new improved scheme based on hash function. The modified scheme resists illegal access, tracking, eavesdropping, impersonation and replay attack, fits for the case which the tags and readers number is large and is security and efficiency.

Key words: Radio Frequency Identification(RFID), security and privacy, Hash function
