    A comprehensive RFID solution to enhance inpatient medication safety

    Errors involving medication administration can be costly, both in financial and in human terms. Indeed, there is much potential for errors due to the complexity of the medication administration process. Nurses are often singled out as the only responsible of these errors because they are in charge of drug administration. Nevertheless, the interventions of every actor involved in the process and the system design itself contribute to errors (Wakefield et al. (1998) [23]). Proper inpatient medication safety systems can help to reduce such errors in hospitals. In this paper, we review in depth two recent proposals (Chien et al. (2010) [7]; Huang and Ku (2009) [12]) that pursue the aforementioned objective. Unfortunately, they fail in their attempt mainly due to their security faults but interesting ideas can be drawn from both. These security faults refer to impersonation and replay attacks that could produce the generation of a forged proof stating that certain medication was administered to an inpatient when it was not. We propose a leading-edge solution to enhance inpatient medication safety based on RFID technology that overcomes these weaknesses. Our solution, named Inpatient Safety RFID system (IS-RFID), takes into account the Information Technology (IT) infrastructure of a hospital and covers every phase of the drug administration process. From a practical perspective, our system can be easily integrated within hospital IT infrastructures, has a moderate cost, is very ease to use and deals with security aspects as a key point.This work was partially supported by the Netherlands Organization for Scientific Research (NWO) under the RUBICON grant "Intrusion Detection in Ubiquitous Computing Technologies" awarded to Aikaterini Mitrokotsa.Publicad

    Distributed Wireless Algorithms for RFID Systems: Grouping Proofs and Cardinality Estimation

    The breadth and depth of the use of Radio Frequency Identification (RFID) are becoming more substantial. RFID is a technology useful for identifying unique items through radio waves. We design algorithms on RFID-based systems for the Grouping Proof and Cardinality Estimation problems. A grouping-proof protocol is evidence that a reader simultaneously scanned the RFID tags in a group. In many practical scenarios, grouping-proofs greatly expand the potential of RFID-based systems such as supply chain applications, simultaneous scanning of multiple forms of IDs in banks or airports, and government paperwork. The design of RFID grouping-proofs that provide optimal security, privacy, and efficiency is largely an open area, with challenging problems including robust privacy mechanisms, addressing completeness and incompleteness (missing tags), and allowing dynamic groups definitions. In this work we present three variations of grouping-proof protocols that implement our mechanisms to overcome these challenges. Cardinality estimation is for the reader to determine the number of tags in its communication range. Speed and accuracy are important goals. Many practical applications need an accurate and anonymous estimation of the number of tagged objects. Examples include intelligent transportation and stadium management. We provide an optimal estimation algorithm template for cardinality estimation that works for a {0,1,e} channel, which extends to most estimators and ,possibly, a high resolution {0,1,...,k-1,e} channel

    Distributed Group Authentication for RFID Supply Management

    We investigate an application of Radio Frequency Identification (RFID) referred to in the literature as group scanning, in which an RFID reader device interrogates several RFID tags to establish “simultaneous” presence of a group of tags. Our goal is to study the group scanning problem in strong adversarial settings and show how group scanning can be used in distributed applications for supply chain management. We present a security framework for group scanning and give a formal description of the attending security requirements. Our model is based on the Universal Composability framework and supports re-usability (through modularity of security guarantees). We propose two novel protocols that realize group scanning in this security model, based on off-the-shelf components such as low-cost (highly optimized) pseudorandom functions, and show how these can be integrated into RFID supply-chain management system

    Security and privacy issues of physical objects in the IoT: Challenges and opportunities

    Get PDF
    In the Internet of Things (IoT), security and privacy issues of physical objects are crucial to the related applications. In order to clarify the complicated security and privacy issues, the life cycle of a physical object is divided into three stages of pre-working, in-working, and post-working. On this basis, a physical object-based security architecture for the IoT is put forward. According to the security architecture, security and privacy requirements and related protecting technologies for physical objects in different working stages are analyzed in detail. Considering the development of IoT technologies, potential security and privacy challenges that IoT objects may face in the pervasive computing environment are summarized. At the same time, possible directions for dealing with these challenges are also pointed out

    Attacks on Karlsson and Mitrokotsa\u27s Grouping-Proof-Distance-Bounding Protocol

    Get PDF
    In the recent IEEE communication letter ``Grouping-Proof-Distance-Bounding Protocols: Keep All Your Friends Close by Karlsson and Mitrokotsa, a protocol for grouping-proof distance-bounding (GPDB) is proposed. In this letter, we show that the proof that is generated by the proposed GBDP protocol does not actually prove anything. Furthermore, we provide a construction towards a distance-bounding grouping-proof, however it remains unclear if one can ever truly combine (privacy-preserving) distance-bounding and a grouping-proof

    SLEC: A Novel Serverless RFID Authentication Protocol Based on Elliptic Curve Cryptography

    Get PDF
    Radio Frequency Identification (RFID) is one of the leading technologies in the Internet of Things (IoT) to create an efficient and reliable system to securely identify objects in many environments such as business, health, and manufacturing areas. Since the RFID server, reader, and tag communicate via insecure channels, mutual authentication between the reader and the tag is necessary for secure communication. The central database server supports the authentication of the reader and the tag by storing and managing the network data. Recent lightweight RFID authentication protocols have been proposed to satisfy the security features of RFID communication. A serverless RFID system is a new promising solution to alternate the central database for mobile RFID models. In this model, the reader and the tag perform the mutual authentication without the support of the central database server. However, many security challenges arise from implementing the lightweight RFID authentication protocols in the serverless RFID network. We propose a new robust serverless RFID authentication protocol based on the Elliptic Curve Cryptography (ECC) to prevent the security attacks on the network and maintain the confidentiality and the privacy of the authentication messages and tag information and location. While most of the current protocols assume a secure channel in the setup phase to transmit the communication data, we consider in our protocol an insecure setup phase between the server, reader, and tag to ensure that the data can be renewed from any checkpoint server along with the route of the mobile RFID network. Thus, we implemented the elliptic curve cryptography in the setup phase (renewal phase) to transmit and store the data and the public key of the server to any reader or tag so that the latter can perform the mutual authentication successfully. The proposed model is compared under the classification of the serverless model in term of computation cost and security resistance
