Research on Encryption Model Based on AES and ECC in RFID

Since the cost of RFID tags reducing constantly, the scale of its applications enlarges in industries and extends to various fields in our daily work and life. However, due to the openness of RFID, it owns a high attack risk when applied. This paper presents a model based on AES and ECC, which can protect users´ privacy and implement access controls. This model takes advantage of both the virtues of a symmetric encryption algorithm and asymmetric encryption algorithm, encrypting AES key with ECC and empowering the client to encrypt system´s ECC public key by using an ECC private key.
