An effective RFID authentication protocol

The Radio Frequency Identification (RFID) is an automatic identification system, which is widely used for industrial and individual applications. However, features of RFID systems present potential security and privacy problems. In an effort to resolve these problems and protect the users from tracing and also to support Low-cost RFID, in this paper, we propose an RFID security method that achieves all requirements based on a hash function and a symmetric key cryptosystem. In addition, our proposed method provides not only high-security but also high-efficiency.
