A RFID Authentication Protocol Based on Zero Knowledge Proof

Abstract

The RFID tag offers a viable and powerful replacement for barcodes.The challenge in providing security for low cost RFID tags is that they are computationally weak devices,unable to perform even basic symmetrickey cryptographic operations.In this paper,the risk of security in RFID technology is discussed,so the authentication protocol is very necessary.However,there are some disadvantages in the two types of authentication protocols which are widely used at present.An authentication protocol based on zero knowledge proof which is suitable for RFID technology is put forward,and its validity and performance is analyzed.
