Methodology and Development of Industrial-Scale Remote Access Control Laboratory

During the coronavirus disease 2019 (COVID-19), there were significant disruptions to education in Turkey, just like worldwide. The idea of creating a remote access control laboratory was proposed to address the laboratory access problem for students in the Department of Control and Automation Engineering (CAE) at Istanbul Technical University (ITU). However, as the number of experiment setups increases, these systems’ maintenance, robustness, and reusability emerge as significant challenges. This paper suggests a methodology for developing industrial-scale remote access control laboratory applications using industrial automation and industry 4.0 architectures. The methodology was successfully integrated into the remote access control laboratory system with six experimental setups in the department of CAE at ITU, enabling students to take the control laboratory classes online. The remote-access control laboratory system enabled quarantined students to participate in lab lessons, reducing the need for face-to-face experiments and enabling social distancing. This system continued post-pandemic, becoming crucial for control laboratories.

Revolutionizing Home Security: A Comprehensive Overview of an Advanced RFID Door Lock System for Keyless Access and Smart Home Protection

The abstract presents a cutting-edge RFID door lock system that does away with traditional physical keys to improve home security. The system uses state-of-the-art components, such as an RFID (Radio-Frequency Identification) reader and an Arduino microcontroller, to provide a safe, keyless access option for homes. This technology provides homes with more protection and convenience, which is a comfort in a world where theft and unwanted access are ongoing issues. Conventional keys are not the best option for home security because they can be stolen, lost, or duplicated. By using customized RFID cards or key fobs, the RFID door lock system, on the other hand, streamlines the entry procedure while significantly lowering the possibility of unwanted access. An RFID reader module, an Arduino microcontroller, and an electronic locking mechanism are the three most crucial parts of the system. Once the authenticity of the card has been confirmed by the RFID reader, the Arduino microcontroller will utilize the obtained data to initiate the lock. Additionally, the system can be improved with features like smartphone applications for remote access control, which let homeowners monitor and grant access from a distance. This RFID door lock system has many advantages for homeowners, including strong security features, user-friendliness, and the capacity to monitor access events. These features provide homeowners with convenience and peace of mind. RFID-based security systems are an important development in the rapidly developing field of smart home technology.

Application of Industrial Remote Access Control Laboratory

An industrial-scale remote access control laboratory system was developed to address the potential lack of practical laboratory experience for Control and Automation Engineering (CAE) students at Istanbul Technical University (ITU) in response to the coronavirus pandemic 2019 (COVID-2019). The system consists of six fundamental control theory experiments and aims to test fundamental control engineering topics such as mathematical modeling, system identification, controller design, and design comparison. These experiments are integrated into a remote access system using industry 4.0 methodologies, allowing students to use the experiments remotely over web-based user interfaces. The system has necessary capabilities such as remote control, online experimentation, graphs and charts, live camera view, data storage, accessibility options, and security for robust interaction with students. Two surveys were conducted to collect feedback from students who have not used the system and those who have used it for at least a semester. The results of the first survey showed that students appreciate the opportunity of remote-access laboratory usage on control experiments and would consider using it. The results of the second survey demonstrated that the system fulfills the varied requirements of students and received high overall satisfaction. Overall, the demand for an industrial-scale remote access control laboratory has been met, driven by the COVID-19 pandemic and the dynamic environment of engineering education.

Bilinear pairing-based access control and key agreement scheme for smart transportation

Internet of Vehicles (IoV) enabled Intelligent Transportation System (ITS) allows smart vehicles to communicate with other vehicles on road, humans (customers or pedestrians), infrastructure (parking areas, traffic lights etc), Internet, Cloud etc. The vehicles communicate with other entities over wireless open channels directly or indirectly through messages or beacons. Open channel allows various attacks, like replay, man-in-the-middle, impersonation, fabrication etc., during communication. Also, malicious vehicles can be deployed in the network to misuse or have an unauthorized access to the services. To mitigate these issues, we propose a new remote access control scheme that ensures the secure communication among the vehicles. The vehicles are dynamic in nature in an IoV paradigm, that is, they are not under fixed domains. Therefore, whenever a vehicle changes its location it has to register to the nearest trusted authority (TA) in offline or secured channel mode. To make it applicable, we propose remote registration of the vehicles via the TA. Access control mechanism occurs in two phases: 1) node authentication phase, where vehicles are remotely authenticated by TA and 2) key agreement phase, where after successful mutual authentication they compute a session key by using cryptographic techniques and pre-loaded information. The computed secret session keys are used for ensuring secure communications in future between two vehicles in a cluster as well. Informal security analysis along with formal security verification using the broadly-used Automated Validation of Internet Security Protocols and Applications (AVISPA) show that our access control scheme is secured against various potential attacks. We also show the competency of our scheme by comparing it with other existing schemes in terms of computation and communication costs.

Automatic speaker verification system for dysarthric speakers using prosodic features and out-of-domain data augmentation

A communication disorder is an impairment of a person’s ability to talk or communicate appropriately. Dysarthria is a common neuro-motor speech communication disorder that can be caused by neurological damage. Dysarthria may affect the articulation, phonation, and prosody of a speaker. Dysarthria patients have poor neuromotor coordination and other physical impairments, making it difficult to utilize an interactive keyboard or other user interfaces. The ASV system can make biometric applications more accessible to dysarthric speakers by eliminating the need for them to remember cumbersome and unique authentication numbers and passwords. In this paper, we presented a study on developing an automatic speaker verification (ASV) system for dysarthria patients with varying speech intelligibility to assist them in remote access control and voice-based biometric applications. In the initial part of our proposed approach, we included a duration modification-based data augmentation module in the front end of the ASV system. Since prosody deficits are one of the early indicators of dysarthria, we investigated the role of prosodic variables in combination with the traditional Mel-frequency cepstral coefficients (MFCC). The prosodic variables explored in this study include pitch, loudness, and voicing probability. Separate i-vector and x-vector models are trained and compared using individual MFCC, prosodic variables, and their combinations. The experimental results showed that the proposed approach based on combining MFCC and prosody features along with duration-modification-based data augmentation produced promising results.

For remote access and appliance control, the ESP32 microcontroller is utilised in the current project. Finally, this project's usage of augmented reality enables users to interact directly with all of the objects in their immediate environment. In order to control two relays both via and without the internet, this project uses an ESP32, an IoT app, augmented reality, and a switch.

Water Utility Conservation and Management Approach Using IoT

Abstract: The demand for water supply has increased unpredictably worldwide over the past few decades, posing a major challenge. To overcome this challenge, an IoT-based water monitoring and control approach is presented, which supports realtime internet-based data collection. The device comprises a computer system (central hub), an IoT module, a switching unit, and a Zigbee module. The Internet of Things is a network of devices embedded with electronics, software, and sensors that enable them to exchange and analyze data. The centralized hub distributes water individually based on the needs of each household, assisted by IoT integration of communications, control, and information processing across the systems used. This allows water quantity and quality to be sensed at each structure in a particular sector, providing remote access control of the water supply. The centralized hub monitors and shares water among localized tanks or resupplies water from its reservoir according to a rank’s deficit or excess water level. Personal area networks are created in this scenario where a wireless connection is required across the system. UV treatment is deployed to improve the quality of water distributed to every household, and fluoride content level along with hardness checking is done using respective test meters. Overall, the IoT-based water monitoring and control approach design presents an innovative solution to the increasing demand for water supply, enabling efficient distribution and ensuring water quality.

The benefit of using this special client file is portability and ease of acquirement, especially in school online portals, online resources portals, and e-commerce portals. The characteristics and design considerations that make smart card tamper resistant are reviewed. Techniques and characteristics to make a client file in an external memory to exhibit a lightweight tamper resistant property has been formulated. The Kumari et al.'s scheme, which is the latest research that uses external memory for remote user authentication, has been reviewed. The basic system design and software design of the proposed client file is presented and modeled. This will enable implementation of the proposed system using any prepared programming or scripting language of one's choice. The proposed scheme and reviewed scheme are also evaluated for efficiency, tamper resistance, and impersonation attack.

A ground-based remote sensing system for high-frequency and real-time monitoring of phytoplankton blooms

The worldwide expansion of phytoplankton blooms has severely threatened water quality, food webs, habitat stability and human health. Due to the rapidity of phytoplankton migration and reproduction, high-frequency information on phytoplankton bloom dynamics is crucial for their forecasting, treatment, and management. While several approaches involving satellites, in situ observations and automated underwater monitoring stations have been widely used in the past several decades, they cannot fully provide high-frequency and continuous observations of phytoplankton blooms at low cost and with high accuracy. Thus, we propose a novel ground-based remote sensing system (GRSS) that can monitor real-time chlorophyll a concentrations (Chla) in inland waters with a high frequency. The GRSS mainly consists of three platforms: the spectral measurement platform, the data-processing platform, and the remote access control, display and storage platform. The GRSS is capable of obtaining a remote sensing irradiance ratio (R(λ)) of 400–1000 nm at a high frequency of 20 s. Eight different Chla retrieval algorithms were calibrated and validated using a dataset of 481 pairs of GRSS R(λ) and in situ Chla measurements collected from four inland waters. The results showed that random forest regression achieved the best performance in deriving Chla (R2 = 0.95, root mean square error = 13.40 μg/L, and mean relative error = 25.7%). The GRSS successfully captured two typical phytoplankton bloom events in August 2021 with rapid changes in Chla from 20 μg/L to 325 μg/L at the minute level, highlighting the critical role that this GRSS can play in the high-frequency monitoring of phytoplankton blooms. Although the algorithm embedded into the GRSS may be limited by the size of the training dataset, the high-frequency, continuous and real-time data acquisition capabilities of the GRSS can effectively compensate for the limitations of traditional observations. The initial application demonstrated that the GRSS can capture rapid changes of phytoplankton blooms in a short time and thus will play a critical role in phytoplankton bloom management. From a broader perspective, this approach can be extended to other carriers, such as aircraft, ships and unmanned aerial vehicles, to achieve the networked monitoring of phytoplankton blooms.

Power IoT System Architecture Integrating Trusted Computing and Blockchain

With the construction of power Internet of Things, the network scale is constantly expanding, the network structure is increasingly complex, and the number of terminals is increasing rapidly, resulting in huge pressure on network security protection, and it is urgent to build a credible operation environment to ensure that the Internet of Things runs safely and reliably. This paper proposes a power Internet of Things architecture combining trusted computing and blockchain. The architecture ensures the credibility and security of the terminal based on remote integrity verification and access control policy verification. A method for malicious node detection based on blockchain (MMNDB) is placed in acquisition layer. It is used to monitor the status of each acquisition devices in time, detect the malicious terminal in time, isolate the suspicious terminal with low credibility from the power Internet of Things, and ensure credibility of the acquisition terminal and the data collected. Under premise of ensuring the communication efficiency of the power communication network, this architecture can greatly ensure the stable working of the power Internet of Things.

An IoT-based Smart Home System for Disabled People

Internet of Things (IoT) envisions a future in which physical objects and the digital world can communicate. Technical communications among appropriate information can create new categories of applications and services. Today, IoT is considered a suitable infrastructure technology for low-range wireless home control systems. In fact, smart homes and buildings provide a wide range of services, applications, equipment, networks, and systems that work together to provide an intelligent environment in areas such as security, control, communications, leisure, and comfort. The purpose of this research is an implementation of an IoT-based Smart home system that provides remote access control for disabled people to open the door lock and turn on or off the lights. Besides, this IoT-based smart home system was extended with two 2-Channel Relay Modules, which assign four keys to direct different components. In addition, this system offers a safe home environment that monitored any hazardous gas leakage, smoke, and fire, or unauthorized person. The motion sensor with a dual purpose has a bright feature that enables two applications: Energy Management System and Security System. Moreover, there are three options for users to open the door for authorized people: Using the Android application on their smartphones, voice command via Google assistant, and the "Unlock door pattern." Authorized people such as friends and family, caregivers, or dog walkers, can unlock the door by physically entering the key pattern via embedded switch buttons (doorbell, B, and C). The camera in this project gets activated as soon as someone rings the doorbell; a snapshot of the current situation behind the door will be sent to the registered user with a notification email. If the entered key pattern does not match the "Unlock door pattern," the alarm system will be triggered. The significance of this research is to provide a solution to help disabled people to live as conveniently and safely as possible in their homes.

ECC-based lightweight authentication and access control scheme for IoT E-healthcare

The E-healthcare system has a complex architecture, diverse business types, and sensitive data security. To meet the secure communication and access control requirements in the user–medical server, user–patient, patient–medical server, and other scenarios in the E-healthcare system, secure and efficient authenticated key agreement and access authorization scheme need to be studied. However, the existing multi-server solutions do not consider the authentication requirements of the Wireless Body Area Network (WBAN) and are not suitable for user–patient, patient–medical server scenarios; most of the existing WBAN authentication schemes are single-server type, which are difficult to meet the requirements of multi-server applications, and the study of user–patient real-time scenarios has not received due attention. This work first reveals the structural flaws and security vulnerabilities of the existing typical schemes and then proposes an authentication and access control architecture suitable for multiple scenarios of the E-healthcare system with separate management and business and designs a novel ECC-based multi-factor remote authentication and access control scheme for E-healthcare using physically unclonable function (PUF) and hash. Security analysis and efficiency analysis show that the new scheme has achieved improved functionality and higher security while maintaining low computational and communication overhead.

A blockchain-based access control scheme for smart home

With the advancement of technology and economy, the scale of the smart home industry has exploded. While improving people’s lives, smart home systems are facing threats to privacy leaks, malicious attacks, and structural security. Effective security mechanisms are very important for protecting valuable data in smart home systems. Access control helps information systems prevent malicious access, thereby reducing the risk of privacy leakage. Blockchain can provide security support for the Internet of Things system due to its advantages of decentralization and immutability. Therefore, in this paper, a smart home access control scheme based on blockchain is proposed. The scheme uses Hyperledger Fabric and implements access control strategies through smart contracts. By designing a hybrid access control model based on dynamic attribute-based access control and static access control matrix, the remote access control initiated by the user through the Internet and the access control between local devices are well guaranteed at the same time. Through safety analysis and performance evaluation, the feasibility of the proposed scheme is demonstrated.

Применение методов ортогонализации псевдоспектров шагов для идентификации человека

A method for processing audio signals of steps of various people in order to effectively separate pseudospectra of signals that can be further subjected to the classification procedure is proposed. The model of a human steps detector was based on the dynamic parameters of the foot position when walking. To record step signals, vibroacoustic sensors were used, sensitive to mechanical and acoustic vibrations in the frequency range from 10 to 1000 Hz. The processing of recorded step signals involved calculating their envelope and then calculating the pseudospectra of the envelope. The procedure for orthogonalization of the pseudospectra of steps for their effective frequency diversity can be used as the basis for the operation of an automated Remote Access Control System. This system can find the application in areas where for one reason or another it is impossible to install another biometric system or is extremely inconvenient, for example, to control access to a room into which the working personnel enter in a special uniform, gloves, and goggles.

Colloidal PbS Quantum Dots for Visible-to-Near-Infrared Optical Internet of Things

The emergence of optical Internet of Things (optical-IoT) for sixth-generation (6G) networks has been envisaged to relieve the bandwidth congestion in the conventional radio frequency (RF) channel, and to support the ever-increasing number of smart devices. Among the plethora of device innovations deemed essential for fortifying the development, herein we report on the visible-to-near-infrared color-conversion luminescent-dyes based on lead sulphide quantum dots (PbS QDs), so as to achieve an eye-safe high-speed optical link. The solution-processed PbS QDs exhibited strong absorption in the visible range, radiative recombination lifetime of 6.4 $\mu$ s, as well as high photoluminescence quantum yield of up to 88%. Our proof-of-principle demonstration based on an orthogonal frequency-division multiplexing (OFDM) modulation scheme established an infrared data transmission of 0.27 Mbit/s, readily supporting an indoor optical-IoT system, and shed light on the possibility for PbS-integrated transceivers in supporting remote access control of multiple nodes. We further envisaged that our investigations could find applications in future development of solution-processable PbS-integrated luminescent fibers, concentrators, and waveguides for high-speed optical receivers.

VOD-ADAC: Anonymous Distributed Fine-Grained Access Control Protocol with Verifiable Outsourced Decryption in Public Cloud

Remote data access control is of crucial importance in public cloud. Based on its own inclinations, the data owner predefines the access policy. When the user satisfies the data owner's access policy, it has the right to access the data owner's remote data. In order to improve flexibility and efficiency of remote data access control, attribute-based encryption (for short, ABE) is used to realize the remote data fine-grained access control. For the low-capacity terminals, verifiable outsourced decryption is a very attractive technique. In the real application scenarios, the user's attributes are usually managed by many authorities. When some authorized users access some sensitive remote data, they hope to preserve their identity privacy. From the two points, we propose an anonymous distributed fine-grained access control protocol with verifiable outsourced decryption in public cloud (for short, VOD-ADAC). VOD-ADAC is a novel concept which is proposed for the first time in the paper. By adopting the pseudonym technique, the user's high anonymity can be achieved by frequently changing the independent pseudonyms at some highly social spots. This paper formalizes the system model and security model of VOD-ADAC protocol. Then, by using hybrid encryption technique of distributed ABE and symmetric encryption, a concrete VOD-ADAC protocol is designed from the bilinear pairings. Through security analysis and performance analysis, our proposed VOD-ADAC protocol is provably secure and efficient.

A Novel Remote Access Control for the Real-time Streaming Data of IP Cameras

IPatient Privacy Copyright Cloud Management

The advent and rapid rise of network technology and cloud computing have led to new opportunities for ushering in a new era in telehealth. Thanks to the Internet of Things (IoT) and advances in 5G communication, telehealth is expanding and shows no signs of slowing down. It provides patients including elderly and disabled patients with convenient and easy access to healthcare services across space and time. However, the continuous real-time transmission of health information over networks also exposes private data to the risk of being intercepted by third parties. The privacy of the primary individual patient must be managed under the protection of the patient’s anonymous key while storing, transferring, sharing, and adding privacy rights. A question arises: How can we design a secure communication environment for remote access control to personal privacy matters? The patient’s electronic medical record is protected by the patient’s private key, and our scheme provides a real anonymous design for the patient with absolute autonomy over their privacy. Each update of the cloud medical records is patient-led and performed in a secure tunnel. As a result, this study reveals that the cloud-based iPatient privacy copyright management fully controlled by an individual patient is indeed safe and effective.
