“…Since regular RFID tags cannot be turned-off, this is usually done by disrupting the wireless communications between the reader and tag so that the unauthorized reader cannot get any meaningful data from the tags. The powerful tag can be a modified RFID tag [21], or a specially designed embedded device [22], [23]. The main difference is that in previous solutions, the powerful tag was designed to prevent an unauthorized reader from accessing the rest of the tags.…”

The proliferation of RFID tags means that an RFID reader will often interact with large groups of RFID tags. However, the majority of RFID security research is still focused on securing single reader-single tag interaction, which is unlikely to be scalable to larger groups of tags. In this paper, we propose a protocol that allows a large group of tags to authenticate a reader. Our technique relies on using a more powerful RFID tag, known as a computational RFID tag (CRFID), which is included into the large group of tags. Theoretical analysis and simulation experiments show that our new protocol is secure and efficient.

“…It shows that the well-used data security policies can guarantee information security for low-cost passive tags. In addition, RFID reader’s access to tag can be controlled through some schemes, such as mutual authentication [ 7 ], light-weighted cryptographic algorithms [ 8 ], collision-resolution protocols [ 9 ], blocking technology [ 10 ], etc ., which can ensure the integrity and credibility of tag information with minimum information leakage and legality of tag owners. Zhou et al proposed the Smart RFID Keeper (SRK), which controls reader’s unauthorized access to tags based on blocking technology [ 11 ].…”

The traditional Radio Frequency Identification (RFID) system, in which the information maintained in tags is passive and static, has no intelligent decision-making ability to suit application and environment dynamics. The Second-Generation RFID (2G-RFID) system, referred as 2G-RFID-sys, is an evolution of the traditional RFID system to ensure better quality of service in future networks. Due to the openness of the active mobile codes in the 2G-RFID system, the realization of conveying intelligence brings a critical issue: how can we make sure the backend system will interpret and execute mobile codes in the right way without misuse so as to avoid malicious attacks? To address this issue, this paper expands the concept of Role-Based Access Control (RBAC) by introducing context-aware computing, and then designs a secure middleware for backend systems, named Two-Level Security Enhancement Mechanism or 2L-SEM, in order to ensure the usability and validity of the mobile code through contextual authentication and role analysis. According to the given contextual restrictions, 2L-SEM can filtrate the illegal and invalid mobile codes contained in tags. Finally, a reference architecture and its typical application are given to illustrate the implementation of 2L-SEM in a 2G-RFID system, along with the simulation results to evaluate how the proposed mechanism can guarantee secure execution of mobile codes for the system.
