This paper investigates a novel approach of distributing a hidden message via public channels. The proposed approach employs visual subterfuge to conceal secret information within a QR code. Using a QR code reader, any individual can decode the public information contained in the QR code. However, only authorized users who have the necessary credentials will be able to obtain the secret message, which is encoded in the form of a secret QR code. We call this a Covert QR (CQR) code scheme. To embed the secret information, this approach exploits the error correction mechanism inherent in the QR code structure. By using QR codes to conceal information, the proposed scheme has the advantage of reducing the likelihood of attracting the attention of potential adversaries. In addition, the information in QR codes can be scanned and decoded through the visual channel. As such, the secret information can be distributed on printed media and is not restricted to an electronic form. Abstract.

“…For example, it can be seen in Table 1 that QR code version 5 with an error correction level of Q has a total of 4 error correction blocks. The (c, d, e) values for the first 2 blocks are (33, 15,9) while the values for the next 2 blocks are (34, 16,9).…”

“…The relevant factors in this relationship between security and energy use have been explored in a number of recent studies. For example, an application called "Smart Text Compression and Encryption for Short Message Service (STCESMS)", which was based on the Android operating system, was presented by Pizzolante et al [36]; the application was designed to compress and/or encrypt data for transmission via (Short Message Service) SMS while utilizing, as appropriate, a number of strategies influenced by delivery cost or energy consumption objectives. In another study from the same year, Castiglione et al [37] sought to provide a sturdy and reliable data transfer service that would also minimize the overall battery consumption of heterogeneous mobile terminals; to that end, they presented the architecture of a framework that could enable secure and reliable end-to-end data transfers between such devices, while also describing and modeling the power demands of said framework.…”

Abstract:To date, the amount of research conducted regarding the subject of energy-efficient transmission in device-to-device (D2D)-assisted cellular network systems simultaneously utilizing both licensed and unlicensed bands is lacking. This topic is of substantial relevance to emerging 5th-generation (5G) cellular network systems, so the present study was conducted in order to address it in a practical manner. Specifically, this study proposes a simple yet effective algorithm aimed at ensuring efficient energy usage when such network systems make transmissions while utilizing both licensed and unlicensed bands. Based on novel system configurations with respect to bandwidth and link mode configurations, the proposed D2D-assisted transmission algorithm was designed with a system-level perspective in mind in order to yield greater efficiency in terms of transmission mode selection and link mode selection. As a result of these features, the proposed algorithm can not only maintain acceptable rates of transmission for all the connected users, but can also enhance system performance by a significant degree in terms of both energy efficiency and connection efficiency. Moreover, the results of simulations conducted to test the algorithm indicate that it is not only feasible, but, given its simple yet effective design, also easy to implement, such that it can serve as a valuable reference for the operators of 5G networks.

“…In some application fields, it is difficult to maintain the network connection between the reader and the background. In addition, the consistent network connection should take the energy efficiency into account [8][9][10]. On the other hand, in the offline mode, the stable connection between the reader and the background is unnecessary; the reader can collect tag information and generate multiple grouping-proofs without the participation of the verifier.…”

Abstract:As more and more items are tagged with RFID (Radio Frequency Identification) tags, grouping-proof technology is widely utilized to provide a coexistence evidence for a group of related items. Due to the wireless channel used in RFID systems, a security risk exists in the communication between the reader and tags. How to ensure the tag's information security and to generate reliable grouping-proof becomes a hot research topic. To protect the privacy of tags, the verification of grouping-proof is traditionally executed by the verifier, and the reader is only used to collect the proof data. This approach can cause the reader to submit invalid proof data to the verifier in the event of DoP (Deny of Proof) attack. In this paper, an ECC-based, off-line anonymous grouping-proof protocol (EAGP) is proposed. The protocol authorizes the reader to examine the validity of grouping-proof without knowing the identities of tags. From the security and performance analysis, the EAGP can protect the security and privacy of RFID tags, and defence impersonation and replay attacks. Furthermore, it has the ability to reduce the system overhead caused by the invalid submission of grouping-proofs. As a result, the proposed EAGP equips practical application values.
