Research on Hash-Based Low-Cost RFID Security Authentication Protocol

Because RFID does not require line of sight communication, low-cost and efficient operation with these outstanding advantages RFID are being widely used, followed by privacy and security vulnerabilities and other issues. Afterdescribe and analysis the facing security issues and the existing security protocols on the stage, proposed a low-cost RFID security authentication protocol based on hash function, this protocol use hash function and random numbers to ensure the safe and efficient control access between the tags and readers,and from the perspective of quantitative estimates the cost of tag. After setting up the idealized protocol model,by using the BAN logic formal analysis this protocol , and prove the security of protocol theoretically .
