“…Therefore, when building large-scale RFID applications, it is very important to use efficient collision detection protocols that simultaneously identify multiple tags [69]. Many anticollision protocols have been proposed to identify RFID tags, such as the query tree (QT) [70], binary tree (BT) [71], frame-slotted ALOHA protocol (FSA) [72]. Despite this, most protocols have an overall detection efficiency of less than 50% [73].The development of new and better protocols requires the best characteristics of the identification protocol.…”

The Internet of Things (IoT) comprises many technologies, among them is Radio Frequency Identification (RFID), which can be used to track single or multiple objects. This technology has been widely used in healthcare, supply chain, logistics, and asset tracking. However, such applications require a high level of security and privacy and are unfortunately vulnerable to various attacks and threats that need to be addressed in order for RFID-based IoT applications to reach their full potential. To this end, we propose a set of security and privacy guidelines for RFID, supported by modelling guidelines, mitigations, and the attack vectors cohesively. We compare to the state of the art and point out their shortcomings on known guidelines and reason to address these in our model. The overall methodology is as follows: (i) identify the security and privacy guideline features, (ii) highlight the security goals for RFID-based IoT applications, (iii) analyze the features in relation to RFID industrial standards, and relate them to security goals, (iv) summarize attacks and threats against RFID applications and correlate them with violated security goals, (v) derive a set of security and privacy guidelines for RFID applications in accordance with security and privacy by design frameworks. We also describe our derived guidelines in connection with the involved stakeholders, and (vi) outline the existing mitigation strategies to implement our proposed guidelines. Finally, we describe the main limitations of our work that should be investigated in the future and identify the multiple challenges that concern current security strategies.INDEX TERMS Internet of Things;RFID;security guidelines;privacy guidelines;countermeasures;security goals;privacy and security by design;attacks

“…Specifically, if there is only one tag in the reader's coverage, the reader can identify it directly without collision. However, if there are two or more tags within the reader's coverage, these tags will be detected in the same channel simultaneously, resulting in a collision between tags [41]. When tag collision occurs, the reader cannot correctly identify each tag, which will affect the QoS of each vehicle.…”

In this paper, we investigate tags in anti-collision applications of radio frequency identification (RFID) technology in unmanned aerial vehicle (UAV)-aided vehicular ad hoc networks (VANETs). The integration of RFID technology in UAV-aided VANETs can provide reliable traffic-related services for vehicles. However, multiple tags’ simultaneous responses to a reader mounted on a UAV, denoted as tag collision, gravely affect the correct tag detection on each vehicle. Therefore, in order to decrease the collision probability and improve the throughput, we propose a multi-frequency tag identification method. In the proposed scheme, we devise a tag grouping method based on adaptive power control to make the reader dynamically match the optimal frame length. Based on the above matching results, we introduce a tag estimation method using the optimal weight to improve the accuracy of tag estimation. We theoretically analyze the closed-form expression of the security outage probability expression. Finally, our simulation results demonstrate that the proposed tag anti-collision scheme achieved significant performance superiority in terms of the throughput and identification time slots.

Radio frequency identification (RFID) technology facilitates a myriad of applications. In such applications, an efficient reader–tag interrogation process is crucial. Nevertheless, throughout reader–tag communication, significant amounts of time and power are consumed on inescapable simultaneous tag replies (i.e., collisions) due to the lack of carrier sensing at the tags. This paper proposes the modulation cutoff intervals (MCI) process as a novel reader–tag interaction given the lack of carrier sensing constraints in passive RFID tags. MCI is facilitated through a simple digital baseband modulation termination (DBMT) circuit at the tag. DBMT detects the continuous-wave cutoff by the reader. In addition, DBMT provides different flags based on the duration of the continuous-wave cutoff. Given this capability at the tag, the reader cuts off its continuous-wave transmission for predefined intervals to indicate different commands to the interrogated tag(s). The MCI process is applied to tag interrogation (or anti-collision) and tag-counting protocols. The MCI process effect was evaluated by the two protocols under high and low tag populations. The performance of such protocols was significantly enhanced with precise synchronization within time slots with more than 50% and more than 55.6% enhancement on time and power performance of anti-collision and counting protocols, respectively. Through the MCI process, fast and power-efficient tag identification is achieved in inventory systems with low and high tag mobility; alternatively, in addition to the rapid and power efficient interaction with tags, anonymous tag counting is conducted by the proposed process.
