Efficient RFID Authentication Protocol for Minimizing RFID Tag Computation

摘要

RFID systems have become vital technology for realizing ubiquitous computing environments. However, features of RFID systems present potential security and privacy problems. In an effort to resolve these problems, many kinds of security and privacy enhancement technologies have been researched. However, solutions produced to date still have flaws and are not sufficiently effective for real RFID systems such as the EPCglobal network. Therefore, in this paper, to make RFID systems more secure and efficient, improved technology based on password, is proposed. The proposed technology combines an encryption algorithm with a password-derived key, and can be applied to low-cost RFID systems for enhancing the security and privacy of these systems.
