An Improvement on Randomly Changed Identification Protocol for Low-Cost Tags
With the benefits to improve productivity and reduce operation cost, RFID (Radio Frequency Identification) has recently seen a great increase in a wide variety of business information systems. However, the downside in business applications is the problem caused by data security and privacy. Enhancement without extra costs in RFID identification poses new challenges to privacy and security in RFID-driven just-in-time business information systems. In this paper, we propose an unilateral randomly authentication protocol on the basis of one-way hash function for low-cost RFID tags. We illustrate the whole operating procedure of the proposed protocol in a typical RFID system. Experimental results show that the proposed protocol has some security improvements in data consistency and can work against some attacks like eavesdropping and DoS, compared with several existing methods.
