Automated Teller Machines (ATM) are critical to banking operations due to their convenient and widespread use. Apart from queues reduced in banking halls, bank clients can still access services outside the regular operational hours. However, a rise in ATM fraud cases has led to banks improving ATM security by adding security ATM keypad covers, surveillance cameras, and even ATM security booths, measures that were not there at ATMs' inception. The academia is also replete with literature on various ATM designs to enhance the security of the facility and the user. However, proposed solutions rarely build on existing infrastructure and technologies, making them difficult to implement as they require additional equipment. For IoT-based solutions, testing is relegated to the communication of components without evaluating the practicability of the proposed solution. In an effort to correct these challenges and secure an ATM user, this paper introduces a conceptual design of a secure cardless ATM system that leverages existing technologies and infrastructure with little additional costs for implementation. A workshop was then used to identify improvements for future implementation. Recommendations from stakeholders and lessons learned from the workshop are discussed.

The field of Industrial Internet of Things (IIoT) is now being duly recognized as a revolutionary area in industrial automation. With the budding interest of knowledge discovery that helps the businesses in applying technology on a large scale, researchers are now faced with several major security concerns. Blockchain integration is one of the suggested applications of technology that could help secure the data during transmission, storage, and knowledge discovery. Moreover, by integrating smart contracts, a secure architecture could also assimilate accountability during data exchange. Thus, we propose a four-layer security architecture that isolates IIoT devices from user-oriented layers and maintains a record of all IIoT devices registered in the organization to prevent malicious devices from corrupting the database and discovery process. Further, by choosing proof of authority (PoA), we ensure the fair functioning of the Blockchain nodes. Through proxy re-encryption for clients, PoA consensus for Blockchain nodes, and Whitelist-based access control for IIoT Devices, we ensure the legitimacy of all participating nodes. We also implement a prototype using a private Ethereum network with proof of authority consensus and present the time taken for the entire exchange and the gas (ethereum currency) consumed per exchange by the contracts. Also we implemented the secure knowledge discovery to understand the significance of the developed scheme. The results show that the exchange can be implemented in an IIoT environment and work with a reasonable amount of resource consumption.

Ethereum smart contracts enable decentralized applications (dApps) on the blockchain and execution of each transaction on dApps incurs a gas cost (fee). While the gas cost prevents denial-of-service (DoS) attacks and incentivizes miners, unoptimized smart contracts may cause excessive gas waste, resulting in higher transaction costs and reduced scalability. Hence, this paper introduces four novel gas waste detectors integrated into the Slither static analysis framework to identify common gas wastes in Solidity smart contracts, including redundant use of address(this), division by unsigned integers, short constant strings, and unnecessary type casting. We analyzed 397 smart contracts from 53 dApps deployed on Ethereum, uncovering 250 instances of gas waste. Our findings indicate that every dApp analyzed exhibits at least one form of gas waste. Notably, division by unsigned integers emerged as the most prevalent gas waste, while half of the dApps could save gas by optimizing short constant strings. To facilitate further research, the annotated dataset of gas waste instances is available on GitHub.

Terrestrial Radio Propagation (TRP) involves radio wave propagation from one station to another over the surface of the earth. Radio communication systems have been deployed for broadcasting, mobile cellular, and public safety. Radio propagation planning plays a crucial role in designing and deploying terrestrial radio networks. Radio propagation models (Path loss Models) are utilized during the link budget, coverage, and interference estimations. The models guide radio network engineers in choosing appropriate placements of radio network equipment, such as the base stations. However, the high cost attributed to TRP data collection, lack of open access, and accurate TRP datasets hinders the development of path loss models that can reliably predict outcomes for different use cases. To address this problem, this paper aims to present a robust TRP repository that provides a platform for hosting and disseminating TRP datasets, which the research community could use for path loss modeling. The repository was implemented using the latest technologies, and its performance was evaluated. The system has been deployed for public access. © 2023 IEEE.

VR devices are a rapidly emerging type of sensory terminal device in the context of the metaverse, with its immersive use effects attracting a large number of users to experience. However, with the continuous development of virtual reality technology, an increasing number of criminal incidents in the virtual world have raised concerns. VR devices are developed based on the Android system but have their unique security mechanisms. Therefore, how to securely extract and preserve data from VR devices is a crucial concern for digital forensic practitioners. This paper first proposes a method for application data extraction and analysis in a non root environment within the VR ecosystem based on the Linux shared user id mechanism. This method utilizes Edge Developer Tools to debug Vuplex 3D Webview, enabling the extraction of internal storage data from embedded web pages within the application. Subsequently, a combination of decompilation and packet capture techniques is used to analyze the data transmission methods and data interaction logic of applications in the VR ecosystem. Finally, based on the experimental results, a comprehensive assessment of the security of VR devices is conducted in the paper. Data extraction from VR devices is an indispensable part of digital forensics in the era of the metaverse. The research on methods for extracting and analyzing application data in the VR ecosystem in this paper provides valuable reference for future forensic work on VR devices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

\begin{document}$ \rm{Areion} $\end{document} is a family of highly-efficient permutations proposed by Isobe et al. in the Annual Conference on Cryptographic Hardware and Embedded Systems (CHES) 2023, which is designed for short-(fixed)-input-length (SFIL) hash functions. In this paper, we study the preimage attack on \begin{document}$ \rm{Areion\text{-}DM} $\end{document}, an SFIL hash function based on \begin{document}$ \rm{Areion} $\end{document} permutation. Following the previous works of meet-in-the-middle (MITM) preimage attack, we proposed a new mixed integer linear programming-based automatic search model utilizing the linear combination of bytes from different chunks. We introduce a new attribute with new propagation rules, which could simplify the previous models. The new model reduces the number of variables and constraints of superposition technique. To search MITM attacks with lower memory, we add new constraints to limit the size of the stored list. We have identified new preimage attacks on 6-round and 5-round \begin{document}$ \rm{Areion256{\text{-}}DM} $\end{document}. In the case of \begin{document}$ \rm{Areion256} $\end{document} without the final swap, our findings reveal novel preimage attacks on 7-round and 5-round configurations, demonstrating lower memory complexities compared to previous results.

Cloths are one of the basic needs of humans and everyone require them at their sense of fashion. Searching out for the best Tailors within a large city is a very tiresome task. Also, visiting a Tailor without appointment can keep you waiting in a queue which take away consumer’s precious time. To solve the issue, we are developing an android based Tailors application. Application asks for the login credentials of customers and tailors and access for location. By giving access to the location this android app will generate a list of Tailors who are nearby us. Booking of services can be done if customer satisfies with details and work of tailor. Main objective of this project is to build an easy, convenient, efficient and user friendly Application where a customer can find a tailor who can fulfil their requirement and a tailor can find the customers which can increase their growth.

Low Power Wide Area Network (LPWAN) is one of the fastest growing network techniques provides efficient communciations for smart cities, e-Health, industry 4.0 and other applications. LPWAN enables long-rang communciations for M2M and cellular IoT networks. Narrowband-IoT (NB-IoT) is a type of LPWAN developed by 3GPP to connect a wide stream of IoT services and devices. NB-IoT systems rely on the mechanism of repeating the same signal every specified period of time in order to improve radio coverage better than it is in LTE systems. Repetition process is used to enhance the coverage of NB-IoT and for upgrade throughput as well. However, increasing the repetition of the signal significantly may give a negative result relative to the bandwidth limits. A cooperative relay (CoR) can be used beside repetition mechanism to helps reduce bandwidth stress. Moreover, the use of CoR for NB-IoT in physical uplink shared channel with repetitions will enhance the throughput. This paper will evaluate the performance of the CoR to enhance physical uplink shared channel in NB-IoT. The NB-IoT system model is simulated bu MATLAB to demonstrate the use of Cooperative relay (CoR) scheme in NPUSCH for NB-IoT for performance evaluation and comparison of using CoR scheme by considering metrics like data rate, throughput, and delay. The results conclude that in using CoR in NB-IoT gives high performance in overall NoT network throughput. © 2022 IEEE.
