Remlein, Piotr, Rogacki, Mikołaj, Stachowiak, Urszula.  2020.  Tamarin software – the tool for protocols verification security. 2020 Baltic URSI Symposium (URSI). :118–123.
In order to develop safety-reliable standards for IoT (Internet of Things) networks, appropriate tools for their verification are needed. Among them there is a group of tools based on automated symbolic analysis. Such a tool is Tamarin software. Its usage for creating formal proofs of security protocols correctness has been presented in this paper using the simple example of an exchange of messages with asynchronous encryption between two agents. This model can be used in sensor networks or IoT e.g. in TLS protocol to provide a mechanism for secure cryptographic key exchange.
Tavakolan, Mona, Faridi, Ismaeel A..  2020.  Applying Privacy-Aware Policies in IoT Devices Using Privacy Metrics. 2020 International Conference on Communications, Computing, Cybersecurity, and Informatics (CCCI). :1–5.
In recent years, user's privacy has become an important aspect in the development of Internet of Things (IoT) devices. However, there has been comparatively little research so far that aims to understanding user's privacy in connection with IoT. Many users are worried about protecting their personal information, which may be gathered by IoT devices. In this paper, we present a new method for applying the user's preferences within the privacy-aware policies in IoT devices. Users can prioritize a set of extendable privacy policies based on their preferences. This is achieved by assigning weights to these policies to form ranking criteria. A privacy-aware index is then calculated based on these ranking. In addition, IoT devices can be clustered based on their privacy-aware index value. In this paper, we present a new method for applying the user's preferences within the privacy-aware policies in IoT devices. Users can prioritize a set of extendable privacy policies based on their preferences. This is achieved by assigning weights to these policies to form ranking criteria.

The Internet of Things (IoT) has been one of the biggest revelations of the last decade. These cyber-physical systems seamlessly integrate and improve the activities in our daily lives. Hence, creating a wide application for it in several domains, such as smart buildings and cities. However, the integration of IoT also comes with privacy challenges. The privacy challenges result from the ability of these devices to pervasively collect personal data about individuals through sensors in ways that could be unknown to them. A number of research efforts have evaluated privacy policy awareness and enforcement as key components for addressing these privacy challenges. This paper provides a framework for understanding contextualized privacy policy within the IoT domain. This will enable IoT privacy researchers to better understand IoT privacy policies and their modeling.
Luo, Bo, Beuran, Razvan, Tan, Yasuo.  2020.  Smart Grid Security: Attack Modeling from a CPS Perspective. 2020 IEEE Computing, Communications and IoT Applications (ComComAp). :1–6.
With the development of smart grid technologies and the fast adoption of household IoT devices in recent years, new threats, attacks, and security challenges arise. While a large number of vulnerabilities, threats, attacks and controls have been discussed in the literature, there lacks an abstract and generalizable framework that can be used to model the cyber-physical interactions of attacks and guide the design of defense mechanisms. In this paper, we propose a new modeling approach for security attacks in smart grids and IoT devices using a Cyber-Physical Systems (CPS) perspective. The model considers both the cyber and physical aspects of the core components of the smart grid system and the household IoT devices, as well as the interactions between the components. In particular, our model recognizes the two parallel attack channels via the cyber world and the physical world, and identifies the potential crossing routes between these two attack channels. We further discuss all possible attack surfaces, attack objectives, and attack paths in this newly proposed model. As case studies, we examine from the perspective of this new model three representative attacks proposed in the literature. The analysis demonstrates the applicability of the model, for instance, to assist the design of detection and defense mechanisms against smart grid cyber-attacks.
Ackley, Darryl, Yang, Hengzhao.  2020.  Exploration of Smart Grid Device Cybersecurity Vulnerability Using Shodan. 2020 IEEE Power Energy Society General Meeting (PESGM). :1–5.
The generation, transmission, distribution, and storage of electric power is becoming increasingly decentralized. Advances in Distributed Energy Resources (DERs) are rapidly changing the nature of the power grid. Moreover, the accommodation of these new technologies by the legacy grid requires that an increasing number of devices be Internet connected so as to allow for sensor and actuator information to be collected, transmitted, and processed. With the wide adoption of the Internet of Things (IoT), the cybersecurity vulnerabilities of smart grid devices that can potentially affect the stability, reliability, and resilience of the power grid need to be carefully examined and addressed. This is especially true in situations in which smart grid devices are deployed with default configurations or without reasonable protections against malicious activities. While much work has been done to characterize the vulnerabilities associated with Supervisory Control and Data Acquisition (SCADA) and Industrial Control System (ICS) devices, this paper demonstrates that similar vulnerabilities associated with the newer class of IoT smart grid devices are becoming a concern. Specifically, this paper first performs an evaluation of such devices using the Shodan platform and text processing techniques to analyze a potential vulnerability involving the lack of password protection. This work further explores several Shodan search terms that can be used to identify additional smart grid components that can be evaluated in terms of cybersecurity vulnerabilities. Finally, this paper presents recommendations for the more secure deployment of such smart grid devices.

Existing cyber security solutions have been basically developed using knowledge-based models that often cannot trigger new cyber-attack families. With the boom of Artificial Intelligence (AI), especially Deep Learning (DL) algorithms, those security solutions have been plugged-in with AI models to discover, trace, mitigate or respond to incidents of new security events. The algorithms demand a large number of heterogeneous data sources to train and validate new security systems. This paper presents the description of new datasets, the so-called ToNİoT, which involve federated data sources collected from Telemetry datasets of IoT services, Operating system datasets of Windows and Linux, and datasets of Network traffic. The paper introduces the testbed and description of TONİoT datasets for Windows operating systems. The testbed was implemented in three layers: edge, fog and cloud. The edge layer involves IoT and network devices, the fog layer contains virtual machines and gateways, and the cloud layer involves cloud services, such as data analytics, linked to the other two layers. These layers were dynamically managed using the platforms of software-Defined Network (SDN) and Network-Function Virtualization (NFV) using the VMware NSX and vCloud NFV platform. The Windows datasets were collected from audit traces of memories, processors, networks, processes and hard disks. The datasets would be used to evaluate various AI-based cyber security solutions, including intrusion detection, threat intelligence and hunting, privacy preservation and digital forensics. This is because the datasets have a wide range of recent normal and attack features and observations, as well as authentic ground truth events. The datasets can be publicly accessed from this link [1].
Abbas Hamdani, Syed Wasif, Waheed Khan, Abdul, Iltaf, Naima, Iqbal, Waseem.  2020.  DTMSim-IoT: A Distributed Trust Management Simulator for IoT Networks. 2020 IEEE Intl Conf on Dependable, Autonomic and Secure Computing, Intl Conf on Pervasive Intelligence and Computing, Intl Conf on Cloud and Big Data Computing, Intl Conf on Cyber Science and Technology Congress (DASC/PiCom/CBDCom/CyberSciTech). :491–498.
In recent years, several trust management frame-works and models have been proposed for the Internet of Things (IoT). Focusing primarily on distributed trust management schemes; testing and validation of these models is still a challenging task. It requires the implementation of the proposed trust model for verification and validation of expected outcomes. Nevertheless, a stand-alone and standard IoT network simulator for testing of distributed trust management scheme is not yet available. In this paper, a .NET-based Distributed Trust Management Simulator for IoT Networks (DTMSim-IoT) is presented which enables the researcher to implement any static/dynamic trust management model to compute the trust value of a node. The trust computation will be calculated based on the direct-observation and trust value is updated after every transaction. Transaction history and logs of each event are maintained which can be viewed and exported as .csv file for future use. In addition to that, the simulator can also draw a graph based on the .csv file. Moreover, the simulator also offers to incorporate the feature of identification and mitigation of the On-Off Attack (OOA) in the IoT domain. Furthermore, after identifying any malicious activity by any node in the networks, the malevolent node is added to the malicious list and disseminated in the network to prevent potential On-Off attacks.
Mohiuddin, Irfan, Almogren, Ahmad.  2020.  Security Challenges and Strategies for the IoT in Cloud Computing. 2020 11th International Conference on Information and Communication Systems (ICICS). :367–372.
The Internet of Things is progressively turning into a pervasive computing service, needing enormous volumes of data storage and processing. However, due to the distinctive properties of resource constraints, self-organization, and short-range communication in Internet of Things (IoT), it always adopts to cloud for outsourced storage and computation. This integration of IoT with cloud has a row of unfamiliar security challenges for the data at rest. Cloud computing delivers highly scalable and flexible computing and storage resources on pay-per-use policy. Cloud computing services for computation and storage are getting increasingly popular and many organizations are now moving their data from in-house data centers to the Cloud Storage Providers (CSPs). Time varying workload and data intensive IoT applications are vulnerable to encounter challenges while using cloud computing services. Additionally, the encryption techniques and third-party auditors to maintain data integrity are still in their developing stage and therefore the data at rest is still a concern for IoT applications. In this paper, we perform an analysis study to investigate the challenges and strategies adapted by Cloud Computing to facilitate a safe transition of IoT applications to the Cloud.
Sayed, Ammar Ibrahim El, Aziz, Mahmoud Abdel, Azeem, Mohamed Hassan Abdel.  2020.  Blockchain Decentralized IoT Trust Management. 2020 International Conference on Innovation and Intelligence for Informatics, Computing and Technologies (3ICT). :1–6.
IoT adds more flexibility in many areas of applications to makes it easy to monitor and manage data instantaneously. However, IoT has many challenges regarding its security and storage issues. Moreover, the third-party trusting agents of IoT devices do not support sufficient security level between the network peers. This paper proposes improving the trust, processing power, and storage capability of IoT in distributed system topology by adopting the blockchain approach. An application, IoT Trust Management (ITM), is proposed to manage the trust of the shared content through the blockchain network, e.g., supply chain. The essential key in ITM is the trust management of IoT devices data are done using peer to peer (P2P), i.e., no third-party. ITM is running on individual python nodes and interact with frontend applications creating decentralized applications (DApps). The IoT data shared and stored in a ledger, which has the IoT device published details and data. ITM provides a higher security level to the IoT data shared on the network, such as unparalleled security, speed, transparency, cost reduction, check data, and Adaptability.

Ariffin, Sharifah H. S..  2020.  Securing Internet of Things System Using Software Defined Network Based Architecture. 2020 IEEE International RF and Microwave Conference (RFM). :1–5.
Majority of the daily and business activities nowadays are integrated and interconnected to the world across national, geographic and boundaries. Securing the Internet of Things (IoT) system is a challenge as these low powered devices in IoT system are very vulnerable to cyber-attacks and this will reduce the reliability of the system. Software Defined Network (SDN) intends to greatly facilitate the policy enforcement and dynamic network reconfiguration. This paper presents several architectures in the integration of IoT via SDN to improve security in the network and system.

With the improvement of people's living standards, more and more network users access the network, including a large number of infrastructure, these devices constitute the Internet of things(IoT). With the rapid expansion of devices in the IoT, the data transmission between the IoT has become more complex, and the security issues are facing greater challenges. SDN as a mature network architecture, its security has been affirmed by the industry, it separates the data layer from the control layer, thus greatly improving the security of the network. In this paper, we apply the SDN to the IoT, and propose a IoT network architecture based on SDN. In this architecture, we not only make use of the security features of SDN, but also deploy different security modules in each layer of SDN to integrate, analyze and plan various data through the IoT, which undoubtedly improves the security performance of the network. In the end, we give a comprehensive introduction to the system and verify its performance.

Industrial Internet of Things (IIoT) has arisen as an emerging trend in the industrial sector. Millions of sensors present in IIoT networks generate a massive amount of data that can open the doors for several cyber-attacks. An intrusion detection system (IDS) monitors real-time internet traffic and identify the behavior and type of network attacks. In this paper, we presented a deep random neural (DRaNN) based scheme for intrusion detection in IIoT. The proposed scheme is evaluated by using a new generation IIoT security dataset UNSW-NB15. Experimental results prove that the proposed model successfully classified nine different types of attacks with a low false-positive rate and great accuracy of 99.54%. To validate the feasibility of the proposed scheme, experimental results are also compared with state-of-the-art deep learning-based intrusion detection schemes. The proposed model achieved a higher attack detection rate of 99.41%.
Yao, Jiaqi, Zhang, Ying, Mao, Zhiming, Li, Sen, Ge, Minghui, Chen, Xin.  2020.  On-line Detection and Localization of DoS Attacks in NoC. 2020 IEEE 9th Joint International Information Technology and Artificial Intelligence Conference (ITAIC). 9:173–178.
Nowadays, the Network on Chip (NoC) is widely adopted by multi-core System on Chip (SoC) to meet its communication needs. With the gradual popularization of the Internet of Things (IoT), the application of NoC is increasing. Due to its distribution characteristics on the chip, NoC has gradually become the focus of potential security attacks. Denial of service (DoS) is a typical attack and it is caused by malicious intellectual property (IP) core with unnecessary data packets causing communication congestion and performance degradation. In this article, we propose a novel approach to detect DoS attacks on-line based on random forest algorithm, and detect the router where the attack enters the sensitive communication path. This method targets malicious third-party vendors to implant a DoS Hardware Trojan into the NoC. The data set is generated based on the behavior of multi-core routers triggered by normal and Hardware Trojans. The detection accuracy of the proposed scheme is in the range of 93% to 94%.

In this era of rapid network development, Internet of Things (IoT) security considerations receive a lot of attention from both the research and commercial sectors. With limited computation resource, unfriendly interface, and poor software implementation, legacy IoT devices are vulnerable to many infamous mal ware attacks. Moreover, the heterogeneity of IoT platforms and the diversity of IoT malware make the detection and classification of IoT malware even more challenging. In this paper, we propose to use printable strings as an easy-to-get but effective cross-platform feature to identify IoT malware on different IoT platforms. The discriminating capability of these strings are verified using a set of machine learning algorithms on malware family classification across different platforms. The proposed scheme shows a 99% accuracy on a large scale IoT malware dataset consisted of 120K executable fils in executable and linkable format when the training and test are done on the same platform. Meanwhile, it also achieves a 96% accuracy when training is carried out on a few popular IoT platforms but test is done on different platforms. Efficient malware prevention and mitigation solutions can be enabled based on the proposed method to prevent and mitigate IoT malware damages across different platforms.
Azhari, Budi, Yazid, Edwar, Devi, Merry Indahsari.  2020.  Dynamic Inductance Simulation of a Linear Permanent Magnet Generator Under Different Magnet Configurations. 2020 International Conference on Sustainable Energy Engineering and Application (ICSEEA). :1–8.
Recently, some innovations have been applied to the linear permanent magnet generator (LPMG). They are including the introduction of high-remanence rare-earth magnets and the use of different magnet configurations. However, these actions also affect the flow and distribution of the magnetic flux. Under the load condition, the load current will also generate reverse flux. The flux resultant then affects the coil parameters; the significant one is the coil inductance. Since it is influential to the output voltage and output power profiles, the impact study of the permanent magnet settings under load condition is essential. Hence this paper presents the inductance profile study of the LMPG with different magnet configurations. After presenting the initial designs, several magnet settings including the material and configuration were varied. Finite element magnetic simulation and analytical calculations were then performed to obtain the inductance profile of the LPMG. The results show that the inductance value varies with change in load current and magnet position. The different magnet materials (SmCo 30 and N35) do not significantly affect the inductance. Meanwhile, different magnet configuration (radial, axial, halbach) results in different inductance trends.

This paper reports electroplated CoPt permanent magnets samples yielding thicknesses up to 100 μm, deposition rates up to 35 μm/h, coercivities up to 1000 kA/m (1.25 T), remanences up to 0.8 T, and energy products up to 77 kJ/m3. The impact of electroplating bath temperature and glycine additives are systematically studied. Compared to prior work, these microfabricated magnets not only exhibit up to 10X increase in thickness without sacrificing magnetic performance, but also improve the areal magnetic energy density by 2X. Using a thick removeable SU-8 mold, these high-performing thick-film magnets are intended for magnetic microactuators, magnetic field sensors, energy conversion devices, and more.
Wang, Meng, Zhao, Shengsheng, Zhang, Xiaolong, Huang, Changwei, Zhu, Yi.  2020.  Effect of La addition on structural, magnetic and optical properties of multiferroic YFeO3 nanopowders fabricated by low-temperature solid-state reaction method. 2020 6th International Conference on Mechanical Engineering and Automation Science (ICMEAS). :242–246.
Nanosize multiferroic La-doped YFeO3 powders are harvested via a low-temperature solid-state reaction method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman spectra analysis reveal that with La addition, YFeO3 powders are successfully fabricated at a lower temperature with the size below 60 nm, and a refined structure is obtained. Magnetic hysteresis loop illustrates ferromagnetic behavior of YFeO3 nano particles can be enhanced with La addition. The maximum and remnant magnetization of the powders are about 4.03 and 1.22 emu/g, respectively. It is shown that the optical band gap is around 2.25 eV, proving that La doped YFeO3 nano particles can strongly absorb visible light. Both magnetic and optical properties are greatly enhanced with La addition, proving its potential application in magnetic and optical field.

Radio frequency identification system (RFID) is a wireless technology based on radio waves. These radio waves transmit data from the tag to a reader, which then transmits the information to a server. RFID tags have several advantages, they can be used in merchandise, to track vehicles, and even patients. Connecting RFID tags to internet terminal or server it called Internet of Things (IoT). Many people have shown interest in connected objects or the Internet of Things (IoT). The IoT is composed of many complementary elements each having their own specificities. The RFID is often seen as a prerequisite for the IoT. The main challenge of RFID is the security issues. Connecting RFID with IoT poses security threats and challenges which are needed to be discussed properly before deployment. In this paper, we proposed a new distributed encryption algorithm to be used in the IoT structure in order to reduce the security risks that are confronted in RFID technology.
Liu, Zixuan, Yu, Jie.  2020.  Design and Analysis of a New RFID Security Protocol for Internet of Things. 2020 5th International Conference on Information Science, Computer Technology and Transportation (ISCTT). :16–18.
As the core of the third information revolution, the Internet of things plays an important role in the development of the times. According to the relevant investigation and research, we can find that the research on the Internet of things is still in the stage of LAN and private network, and its open advantages have not been fully utilized[1]. In this context, RFID technology as the core technology of the Internet of things, the security protocol plays an important role in the normal use of the technology. With the continuous development of Internet information technology, the disadvantages of security protocol become more and more obvious. These problems seriously affect the popularity of Internet of things technology. Therefore, in the future work, the relevant staff need to continue to strengthen research, according to the future development plan, effectively play the advantages of technology, and further promote its development.
Almohri, Hussain M. J., Watson, Layne T., Evans, David.  2020.  An Attack-Resilient Architecture for the Internet of Things. IEEE Transactions on Information Forensics and Security. 15:3940–3954.
With current IoT architectures, once a single device in a network is compromised, it can be used to disrupt the behavior of other devices on the same network. Even though system administrators can secure critical devices in the network using best practices and state-of-the-art technology, a single vulnerable device can undermine the security of the entire network. The goal of this work is to limit the ability of an attacker to exploit a vulnerable device on an IoT network and fabricate deceitful messages to co-opt other devices. The approach is to limit attackers by using device proxies that are used to retransmit and control network communications. We present an architecture that prevents deceitful messages generated by compromised devices from affecting the rest of the network. The design assumes a centralized and trustworthy machine that can observe the behavior of all devices on the network. The central machine collects application layer data, as opposed to low-level network traffic, from each IoT device. The collected data is used to train models that capture the normal behavior of each individual IoT device. The normal behavioral data is then used to monitor the IoT devices and detect anomalous behavior. This paper reports on our experiments using both a binary classifier and a density-based clustering algorithm to model benign IoT device behavior with a realistic test-bed, designed to capture normal behavior in an IoT-monitored environment. Results from the IoT testbed show that both the classifier and the clustering algorithms are promising and encourage the use of application-level data for detecting compromised IoT devices.

The Extended Triple Diffie-Hellman (X3DH) protocol has been used for years as the basis of secure communication establishment among parties (i.e, humans and devices) over the Internet. However, such a protocol has several limits. It is typically based on a single trust third-party server that represents a single point of failure (SPoF) being consequently exposed to well- known Distributed Denial of Service (DDOS) attacks. In order to address such a limit, several solutions have been proposed so far that are often cost expensive and difficult to be maintained. The objective of this paper is to propose a BlockChain-Based X3DH (BCB-X3DH) protocol that allows eliminating such a SPoF, also simplifying its maintenance. Specifically, it combines the well- known X3DH security mechanisms with the intrinsic features of data non-repudiation and immutability that are typical of Smart Contracts. Furthermore, different implementation approaches are discussed to suits both human-to-human and device-to-device scenarios. Experiments compared the performance of both X3DH and BCB-X3DH.

Lessio, Nadine, Morris, Alexis.  2020.  Toward Design Archetypes for Conversational Agent Personality. 2020 IEEE International Conference on Systems, Man, and Cybernetics (SMC). :3221–3228.
Conversational agents (CAs), often referred to as chatbots, are being widely deployed within existing commercial frameworks and online service websites. As society moves further into incorporating data rich systems, like the internet of things (IoT), into daily life, it is expected that conversational agents will take on an increasingly important role to help users manage these complex systems. In this, the concept of personality is becoming increasingly important, as we seek for more human-friendly ways to interact with these CAs. In this work a conceptual framework is proposed that considers how existing standard psychological and persona models could be mapped to different kinds of CA functionality outside of strictly dialogue. As CAs become more diverse in their abilities, and more integrated with different kinds of systems, it is important to consider how function can be impacted by the design of agent personality, whether intentionally designed or not. Based on this framework, derived archetype classes of CAs are presented as starting points that can hopefully aid designers, developers, and the curious, into thinking about how to work toward better CA personality development.
Fernando, Praveen, Wei, Jin.  2020.  Blockchain-Powered Software Defined Network-Enabled Networking Infrastructure for Cloud Management. 2020 IEEE 17th Annual Consumer Communications Networking Conference (CCNC). :1–6.
Cloud architecture has become a valuable solution for different applications, such as big data analytics, due to its high degree of availability, scalability and strategic value. However, there still remain challenges in managing cloud architecture, in areas such as cloud security. In this paper, we exploit software-defined networking (SDN) and blockchain technologies to secure cloud management platforms from a networking perspective. We develop a blockchain-powered SDN-enabled networking infrastructure in which the integration between blockchain-based security and autonomy management layer and multi-controller SDN networking layer is defined to enhance the integrity of the control and management messages. Furthermore, our proposed networking infrastructure also enables the autonomous bandwidth provisioning to enhance the availability of cloud architecture. In the simulation section, we evaluate the performance of our proposed blockchain-powered SDN-enabled networking infrastructure by considering different scenarios.
