The Research On Security Of Modern Logistics Information System Based On RFID

RFID technology is considered as one of the most influential information technologies in 21st century, the application of RFID technology in modern logistics has brought unprecedented opportunity for it, the visualization of the supply chain is improved, inventory is reduced, the process of enterprise's informatization is speed up and customer service is improved. But since the transmission of data is completely opened through wireless channel, this has potential risks and provided an opportunity for the attacker. Therefore we must adopt appropriate security mechanisms to solve the problems.The research of this paper is based on the background and the actual demand mentioned in the first paragraph, the main work of this paper is as follows:1. On the basis of the study of RFID technology in modern logistics as well as all aspects of the application, we analysis the system's hidden danger as well as all of means of attacks the attacker may use, then establish a model of the attack.2. Design an architecture of the security of modern logistics information system based on RFID by a variety of security mechanisms, including the symmetrical security authentication protocol between the reader and tag which is to verify the identity of the legitimacy before data transmission, the reader's identity authentication by RFID middleware, data encryption when data-processing as well as RFID-based middleware security mechanism.3. Design a symmetric authentication protocol based on a shared key so as to prevent the attacks as illegal reading, eavesdrop, spoofing and replay which exist in RFID system. Prove its advantages compared with the existing security authentication protocol.4. Improve the former protocol and design an multi authentication protocol based on a shared key, so as to reduce the calculation of tag and the reader, give full play to the role of RFID middleware and ultimately achieve system's security.
