To solve the problems of consumers’security and privacy,a new security protocol of RFID based on elliptic curve cryptography(ECC) is proposed,and the security of ECC is based on the difficulty of elliptic curve discrete logarithm problem(ECDLP).Comparing with other asymmetric cryptography,ECC has stronger security,shorter key length,less computation and so on.This protocol uses the elliptic curve Diffie-Hellman(ECDH) and the algorithm of plaintext embedding in elliptic curve,so the data exchanged between RFID tag and reader can be protected by this protocol.By analyzing its security and efficiency,comparison with these protocols based on symmetric cryptography,our protocol can meet the security requirements of RFID systems very well.
