Research on Security of UHF Mobile RFID Systems Based on Privacy Protection

Aimed at the increasing importance of mobile RFID application and the existing circumstances of security for mobile RFID service, from both security and privacy points of view, mobile RFID technology and services are discussed based on the related theories on RFID and mobile communication technology. Furthermore, main security problems and requirements are analyzed in detail for mobile RFID services. On this basis, a security-enhanced service infrastructure is constructed for UHF mobile RFID systems, and a privacy protection scheme is proposed based on hiding original tag ID in order to provide some help for solving various security problems in mobile RFID service. Analysis on the proposed security scheme shows that mobile RFID users' privacy can be protected effectively by introducing the security-enhanced service infrastructure with a transparent transmission mode and modifying tags ID periodically.
