This research reviews some current RFID authentication schemes, discovers their security flaws, and develops a better RFID authentication scheme based on the discovery.
A new low-cost privacy preserving RFID authentication scheme is proposed, using one-way hash function to protect confidentiality and the error-correction code’s characteristic of anonymity and untraceability to measure up the security of RFID system. Security analysis, efficiency evaluation, and comparison with other schemes are also given.
The results show that the proposed RFID authentication scheme achieves not only confidentiality, untraceability, and anonymity but also the applicability to large quantity of tags. Besides, searching the whole database in the server is not required. In addition, breaking one tag will not affect the secure operation of the others. This is the major contribution of this research.
