轻量级RFID隐私保护关键技术研究

Various malicious attacks, security privacy omission and the extremely resource-constrained requirements of RFID tags become the handicap to the development of RFID technology and the bottle neck of their further pervasive usage in recent years. In the consideration of user’s behavior varying with the states of time and space, the changes both in user’s privacy characteristic and the needs for privacy-preserving becomes the new challenge in developing RFID privacy-preserving technology research. Research on lightweight RFID privacy-preserving technology is an important part of ensuring the security of RFID systems in the environment of internet of things. This project is devoted to research on key technology of lightweight RFID privacy-preserving, and is also focused on the construction of lightweight RFID mutual grouping-proof schemes, lightweight RFID time-space privacy-preserving schemes and lightweight RFID hierarchy privacy-preserving schemes and design of attacking model of lightweight RFID privacy-preserving mechanism. Aiming at the characteristics of static authentication, dynamic authentication, forward security, backward security, moving track, anonymous tractability, distributive fusion, hierarchy privacy and ownership transfer, we combine the varying needs of users’ privacy-preserving to construct lightweight RFID privacy-preserving schemes for different application scenarios. The results of this project will reduce the harm caused by RFID privacy leakage effectively, which has high research value and broad application prospects.
