The Research and Implementation of RFID Tag Data Security Based on Hash

Proposes an improved RFID tag data security authentication algorithm based on Hash. The algorithm uses two-way authentication mechanism of the RFID tag and reader, and by the BAN logic to formal analysis. The result show that the algorithm possess forward security, replay attack, spoofing attack, location tracking, distinguish ability and so on. So the algorithm can better solve the RFID tag and reader security issues.
