Our findings underscore the need for holistic approaches that integrate energy-awareness and security measures to fortify the resilience of WSNs, fostering their sustainable deployment in critical applications.

Cloud computing (CC) is vulnerable to existing information technology attacks, since it extends and utilizes information technology infrastructure, applications and typical operating systems. In this manuscript, an Enhanced capsule generative adversarial network (ECGAN) with blockchain based Proof of authority consensus procedure fostered Intrusion detection (ID) system is proposed for enhancing cyber security in CC. The data are collected via NSL-KDD benchmark dataset. The input data is fed to proposed Z-Score Normalization process to eliminate the redundancy including missing values. The pre-processing output is fed to feature selection. During feature selection, extracting the optimum features on the basis of univariate ensemble feature selection (UEFS). Optimum features basis, the data are classified as normal and anomalous utilizing Enhanced capsule generative adversarial networks. Subsequently, blockchain based Proof of authority (POA) consensus process is proposed for improving the cyber security of the data in cloud computing environment.

The proposed approach has attained 33.7\%, 25.7\%, 21.4\% improved accuracy, 24.6\%, 35.6\%, 38.9\% lower attack detection time, and 23.8\%, 18.9\%, 15.78\% lower delay than the existing methods, like Artificial Neural Network (ANN) with blockchain framework, Integrated Architecture with Byzantine Fault Tolerance consensus, and Blockchain Random Neural Network (RNN-BC) respectively.

Recent advances in quantum computing and quantum information theory represent a severe threat to the current state of the art of data protection. In this context, new quantum-safe techniques have emerged in recent decades, which fall into post-quantum and unconditionally secure cryptographic schemes. The firsts rely on computational problems supposed to be hard also for quantum computers. In contrast, the seconds do not depend on the difficulty of a computational problem and are therefore immune to quantum power. In particular, unconditionally secure techniques include Quantum Key Distribution (QKD) protocols for transmitting secret keys thanks to the quantum properties of light. In this work, we discuss QKD networks and post-quantum algorithms, considering their opportunities and limitations and showing that reconciliation between these two directions of cryptography is feasible and necessary for the quantum era.This work is part of the activities of the PON project “Development of quantum systems and technologies for IT security in communication networks” (QUANCOM) which aims to the realization of a metropolitan quantum communication network through the collaboration between universities, research centers and companies operating in the communication market area.

With the popularization of AIoT applications, every endpoint device is facing information security risks. Thus, how to ensure the security of the device becomes essential. Chip security is divided into software security and hardware security, both of which are indispensable and complement each other. Hardware security underpins the entire cybersecurity ecosystem by proving essential primitives, including key provisioning, hardware cryptographic engines, hardware unique key (HUK), and unique identification (UID). This establishes a Hardware Root of Trust (HRoT) with secure storage, secure operation, and a secure environment to provide a trustworthy foundation for chip security. Today s talk starts with how to use a Physical Unclonable Function (PUF) to generate a unique “fingerprint” (static random number) for the chip. Next, we will address using a static random number and dynamic entropy to design a high-performance true random number generator and achieve real anti-tampering HRoT by leveraging static and dynamic entropy. By integrating NISTstandard cryptographic engines, we have created an authentic PUF-based Hardware Root of Trust. The all-in-one integrated solution can handle all the necessary security functions throughout the product life cycle as well as maintaining a secure boundary to achieve the integrity of sensitive information or assets. Finally, as hardware-level protection extends to operating systems and applications, products and services become secure.

Smartphones have completely altered the mobile communication scene. Wi-Fi, global positioning system navigation, high-resolution cameras, and touchscreens with high-speed internet access are just some of the cutting-edge capabilities that these devices offer, allowing users to stay in constant contact with the present. Since many of these features are embedded deeply in the mobile operating system, they are typically inaccessible to the average user. However, Google released Android, a revolutionary operating system. Because of its open system architecture, this platform encourages third-party development and a debugging environment that users may change to create their own unique apps. In this research project, we examine the development of an Emergency Based Remote Collateral Tracking System app on the Android mobile platform from Google. There are three main forms of emergencies: those involving the heart, those involving personal safety, and those involving the roads. Users who own and operate motor vehicles are the primary focus of this app. Our program can keep tabs on the driver’s pulse by connecting to a heart rate monitor. Our application has a backup function in case of anomalies. First, it sends SMS messages containing the user’s location data after using GPS to do so.

These days, safety measures can t be neglected. In a world where digital risks are becoming more prevalent, efficient security has become an essential aspect of any system or business. Protecting valuables now requires a defensive strategy with several layers. Security systems play an important role in today s modern, industrialised society. The security system is primarily intended to address the need for the protection of hard-earned treasures (jewels). Unlike the current method, which uses physical locks that are readily falsified, this system uses Bluetooth and RFID tags in conjunction with digital (electronic) code locks to unlock the door automatically once the series of authentications is validated and emits alarm noises when any discrepancy happens. The ability of subsequent layers of defense to prevent intrusion is unaffected by the failure of an earlier one to provide detection. In this effort, we use IoT to design and build a fully automated security system that will operate with no more human intervention when it is put into place. In addition, the system s overall cost of adoption is far lower than that of any other consumer security solution now on the market.

In today s world, security is a very important issue. People should always keep their belongings safe. To increase security, this research work proposes a IoT-based smart lockers with sensors and access keys with security, verification, and user-friendly tools. This model alerts the user when someone else tries to access their locker and quickly sends an alarm to the authorized user, and provides the option to either grant or reject access to the valid user. In this paper, smart locker is kept registered early to use a locker in the bank, office, home, etc. to ensure safety. The user demands to send an unlock direction with the help of microcontroller NUDE MCU ESP8266 and after accepting the command from the cloud (BLYNK APP), only the user can unlock the closet and access the valuables. This study has also introduced the encroachment detection in lockers with sensors and finally installed smart lockers with fire alarms for security and reliability.

The combination of these cutting-edge solutions establishes a comprehensive security infrastructure, significantly reducing risks associated with conventional lock systems. This research highlights the benefits and applications of these technologies in various settings, emphasizing their role in creating a safer environment for individuals and organizations.

Every person must take precautions in the current pandemic crisis, such as wearing protective gear, keeping a safe distance, cleaning their hands, and avoiding touching anything unless absolutely essential. However, there is a potential of disease transmission while touching objects like tables, doors, cars, and other things. Therefore, this study has proposed a proposal to stop them; the project is based on automation, in which an automatic door closing and opening mechanism has been created once the voice command is given. In this scenario, when a proper voice command is provided, the mechanism is activated to open and close the door automatically. Hence that there is no direct human contact with the door, which will assist stop or slow the spread of pandemic disease. The developed Arduino-based module can automatically close and open the door. These devices produced a regulator for the input, which uses the Android s Bluetooth signal. Arduino-based Android customers may easily open and close the door with their phones by communicating via Bluetooth technology. Within range, Bluetooth Classic (BT) makes it possible to connect an Android device. You may open a door with a personalized audio message and operate it by speaking into modules. Here, everyone is using various modules, such as voice commands, to control various modules. When a voice command is provided, the door will open and close on its own.

The advancement of technology is challenging for designers of the security systems. When securing a property or different valuable items, it must be kept into account that often criminals are equipped with performant electric or electronic devices, constructed to disable security systems and to remove any trace of their activity. In consequence, reliable and fast responding security systems must be constructed. This paper proposes a design based on two different microcontrollers, both using Real Time Operating Systems, which has an increased capability to resist at attacks from intruders, and to warn the authorities as soon as a unauthorized access was detected in the secured space. This project is characterized by a low-cost implementation and an efficient operation, given that it is fast responding, and it contains two physically separated modules, making its disabling by intruders more difficult.

In recent years, the advancement of sensor technologies has revolutionized the field of security systems, enabling more accurate and reliable monitoring solutions. Radar technology, known for its ability to operate effectively in various weather conditions and lighting environments, provides a distinct advantage in maintaining consistent surveillance. By utilizing radio waves, the system can accurately detect movement within its coverage area, making it well-suited for both indoor and outdoor applications. The smart radar security system is an innovative approach that harnesses the power of radar technology to create a robust and efficient security solution. This system employs radar sensors to detect and track movement, presence, and object classification in diverse environments, offering significant advantages over traditional security methods. The core functionality of the proposed system revolves around its ability to detect motion with high precision. The proposed approach represents a significant step forward in security solutions by leveraging radar technology s unique advantages. Hence, this work aims to develop a protype for accurately detection the obstacle motion related to radar applications.

Users can receive real-time alerts and notifications on their smartphones or connected devices whenever unauthorized movement is detected. Additionally, the proposed system can be seamlessly integrated with existing smart home or security systems, allowing for comprehensive and centralized surveillance management. As technology continues to evolve, this system showcases the potential for cutting-edge solutions that prioritize both security and privacy.

This paper highlights the progress toward securing teleoperating devices over the past ten years of active technology development. The relevance of this issue lies in the widespread development of teleoperating systems with a small number of systems allowed for operations. Anomalous behavior of the operating device, caused by a disruption in the normal functioning of the system modules, can be associated with remote attacks and exploitation of vulnerabilities, which can lead to fatal consequences. There are regulations and mandates from licensing agencies such as the US Food and Drug Administration (FDA) that place restrictions on the architecture and components of teleoperating systems. These requirements are also evolving to meet new cybersecurity threats. In particular, consumers and safety regulatory agencies are attracted by the threat of compromising hardware modules along with software insecurity. Recently, detailed security frameworks and protocols for teleoperating devices have appeared. However, a matter of intelligent autonomous controllers for analyzing anomalous and suspicious actions in the system remain unattended, as well as emergency protocols from the point of cybersecurity view. This work provides a new approach for the intraoperative cybersecurity of intelligent teleoperative surgical systems, taking into account modern requirements for implementing into the Surgical Remote Intelligent Robotic System LevshAI. The proposed principal security model allows a surgeon or autonomous agent to manage the operation process during various attacks.

The high directionality of millimeter-wave (mmWave) communication systems has proven effective in reducing the attack surface against eavesdropping, thus improving the physical layer security. However, even with highly directional beams, the system is still exposed to eavesdropping against adversaries located within the main lobe. In this paper, we propose BeamSec, a solution to protect the users even from adversaries located in the main lobe. The key feature of BeamSec are: (i) Operating without the knowledge of eavesdropper’s location/channel; (ii) Robustness against colluding eavesdropping attack and (iii) Standard compatibility, which we prove using experiments via our IEEE 802.11ad/ay-compatible 60 GHz phased-array testbed. Methodologically, BeamSec first identifies uncorrelated and diverse beampairs between the transmitter and receiver by analyzing signal characteristics available through standard-compliant procedures. Next, it encodes the information jointly over all selected beampairs to minimize information leakage. We study two methods for allocating transmission time among different beams, namely uniform allocation (no knowledge of the wireless channel) and optimal allocation for maximization of the secrecy rate (with partial knowledge of the wireless channel). Our experiments show that BeamSec outperforms the benchmark schemes against single and colluding eavesdroppers and enhances the secrecy rate by 79.8\% over a random paths selection benchmark.

Android is the most popular smartphone operating system with a market share of 68.6\% in Apr 2023. Hence, Android is a more tempting target for cybercriminals. This research aims at contributing to the ongoing efforts to enhance the security of Android applications and protect users from the ever-increasing sophistication of malware attacks. Zero-day attacks pose a significant challenge to traditional signature-based malware detection systems, as they exploit vulnerabilities that are unknown to all. In this context, static analysis can be an encouraging approach for detecting malware in Android applications, leveraging machine learning (ML) and deep learning (DL)-based models. In this research, we have used single feature and combination of features extracted from the static properties of mobile apps as input(s) to the ML and DL based models, enabling it to learn and differentiate between normal and malicious behavior. We have evaluated the performance of those models based on a diverse dataset (DREBIN) comprising of real-world Android applications features, including both benign and zero-day malware samples. We have achieved F1 Score 96\% from the multi-view model (DL Model) in case of Zero-day malware scenario. So, this research can be helpful for mitigating the risk of unknown malware.

With the development of streaming media, soft real-time system in today’s life could participate in the use of more extensive areas. The use frequency was also increasing. Consequently, modern processors were equipped with software control mechanisms such as DVFS (Dynamic Voltage Frequency Scaling) to allow operating systems to meet required performance while reducing power consumption. Therefore, we propose a task scheduling algorithm combined DVFS technology and time deterministic cyclic scheduling to achieve energy saving effect. First, the algorithm needed to minimize the preemption between tasks to reduce latency, so we created a buffer to save periodic tasks to avoid preemption. Second, to reduce the computational cost of the scheduling scheme, a scheduling template were designed to perform tasks. In this paper, the scheduling of periodic tasks, task scheduling would be designed when the task scheduling template would be fixed length. Besides, this algorithm supported that task could adopt appropriate voltage and frequency through DVFS technology in idle time under the condition of satisfying task dependence. Experimental analysis showed that the proposed algorithm could effectively reduce the system energy consumption while ensuring the completion of the task.

Employing Trusted Execution Environment (TEE) technology such as ARM TrustZone to deploy sensitive security modules and credentials for secure, authenticated access is the go-to solution to address integrity and confidentiality challenges in untrusted devices. While it has been attracting attention as an effective building block for secure enterprise IT systems (e.g., BYOD), these secure operating systems are often not open-source, and thus system operators and developers have to largely depend on mobile platform vendors to deploy their applications in the secure world on TEE. Our solution, called GateKeeper, addresses the primary obstacle for system operators to adopt ARM TrustZone TEE to deploy their own, in-house security systems, by enabling the operators more control and flexibility on Trusted App (TA) installation and update procedure without mandating involvement of the mobile platform vendors at each iteration. In this paper, we first formulate an ecosystem for enabling such operator-centric TA management, and then discuss the design of GateKeeper, which is a comprehensive framework to enable operator-centric TA management on top of GlobalPlatform specification. We further present a proof-ofconcept implementation using OP-TEE open-source secure OS to demonstrate the feasibility and practical resource consumption (less than 1000 lines of code and 500 KBytes on memory).

The continuously growing importance of today’s technology paradigms such as the Internet of Things (IoT) and the new 5G/6G standard open up unique features and opportunities for smart systems and communication devices. Famous examples are edge computing and network slicing. Generational technology upgrades provide unprecedented data rates and processing power. At the same time, these new platforms must address the growing security and privacy requirements of future smart systems. This poses two main challenges concerning the digital processing hardware. First, we need to provide integrated trustworthiness covering hardware, runtime, and the operating system. Whereas integrated means that the hardware must be the basis to support secure runtime and operating system needs under very strict latency constraints. Second, applications of smart systems cover a wide range of requirements where "one- chip-fits-all" cannot be the cost and energy effective way forward. Therefore, we need to be able to provide a scalable hardware solution to cover differing needs in terms of processing resource requirements.In this paper, we discuss our research on an integrated design of a secure and scalable hardware platform including a runtime and an operating system. The architecture is built out of composable and preferably simple components that are isolated by default. This allows for the integration of third-party hardware/software without compromising the trusted computing base. The platform approach improves system security and provides a viable basis for trustworthy communication devices.
