- Abstract
- In the ubiquitous society of the near future, various customer-oriented intellectual services will be required where RFID systems using wireless recognition technology are widely applied. In these RFID systems, it is important to protect personal information during wireless communication, as well as to keep the price of relative tags affordable. In addition, it is important to make the registration and removal of tags easy, and maintain the processing speed even when the number of tags increases. In this paper, we propose a real-time hash-chain scheme decreasing the pre-calculation mechanism to provide RFID efficiency for ubiquitous services (RHS-US). RHS-US provides a synchronization method between the tag and backend server to improve efficiency during normal authentication by providing fast processing time, while protecting personal information perfectly during abnormal authentication. © 2008 Springer Science+Business Media, LLC.
