A Study on the Security of RFID with Enhancing Privacy Protection

A ubiquitous network environment will make society be able to conveniently access better services anywhere and at any time. The Radio Frequency Identification (RFID) technology will most likely be part of such a manageable society. However, more and more deployment of RFIDs may create some threats to user privacy; therefore privacy protection has become an important issue nowadays. In this thesis, we propose a mutual authentication protocol to enhance the privacy protection, which uses the dynamic identification scheme. In this way, we want to reform some weaknesses which have in the past, or will in the future allow breaches by adversaries. We present a security protocol to prevent some attacks using cryptographic one-way hash functions on the passive tags. Therefore, our proposed method could be deployed in many applications without strong symmetric or asymmetric encryption. We believe that the proposed approach will be available to enhance the protection of a user's privacy.
