The Internet of things (IoT) is intended for ubiquitous connectivity among different entities or “things”. While it provides effective and efficient solutions to many real world challenges, the security aspect of it has always been questioned. The situation is further exacerbated by the number of connected devices growing exponentially. As a result, security and privacy has emerged as a significant challenge for the IoT. In this paper, we aim to provide a thorough survey on IoT security and privacy challenges from the perspective of technologies and architecture used. This work focuses on IoT intrinsic vulnerabilities and their implications to the fundamental information security challenges in confidentiality, integrity, and availability. The approach of this survey is to summarize and synthesize published work in IoT; relate it to the security conjuncture of the field; and project future research directions. 相似文献

The vision of the Internet of Things (IoT) foresees a future Internet incorporating smart physical objects that offer hosted functionality as IoT services. These services when integrated with the traditional enterprise level services form the creation of ambient intelligence for a wide range of applications. To facilitate seamless access and service life cycle management of large, distributed and heterogeneous IoT resources, service oriented computing and resource oriented approaches have been widely used as promising technologies. However, a reference architecture integrating IoT services into either of these two technologies is still an open research challenge. In this article, we adopt the resource oriented approach to provide an end-to-end integration architecture of front-end IoT devices with the back-end business process applications. The proposed architecture promises a programmer friendly access to IoT services, an event management mechanism to propagate context information of IoT devices, a service replacement facility upon service failure, and a decentralized execution of the IoT aware business processes. 相似文献

The number of Internet of Things (IoT) and smart devices capable of producing, consuming and exchanging information is constantly increasing. It is estimated there will be around 30 billion of them in 2020. In most cases, the structures of the information produced by such devices are completely different, thus providing heterogeneous information. This is becoming a challenge for researchers working on IoT, who need to perform homogenisation and pre-processing tasks before using the IoT data. This paper aims to provide an architecture for processing and analysing data from heterogeneous sources with different structures in IoT scopes, allowing researchers to focus on data analysis, without having to worry about the structure of the data sources. This architecture combines the real-time stream processing paradigm for information processing and transforming, together with the complex event processing for information analysis. This provides us with capability of processing, transforming and analysing large amounts of information in real time. The results obtained from the evaluation of a real-world case study about water supply network management show that the architecture can be applied to an IoT water management scenario to analyse the information in real time. Additionally, the stress tests successfully conducted for this architecture highlight that a large incoming rate of input events could be processed without latency, resulting in efficient performance of the proposed architecture. This novel software architecture is adequate for automatically detecting situations of interest in the IoT through the processing, transformation and analysis of large amounts of heterogeneous information in real time. 相似文献

The rapid and unprecedented technological advancements are currently dominated by two technologies. At one hand, we witness the rise of the Internet of Things (IoT) as the next evolution of the Internet. At the other hand, we witness a vast spread of social networks that connects people together socially and opens the door for people to share and express ideas, thoughts, and information. IoT is overpopulated by a vast number of objects, millions of multimedia services, and interactions. Therefore, the search of the right object that can provide the specific multimedia service is considered as an important issue. The merge of these two technologies resulted in new paradigm called Social IoT (SIoT). The main idea in SIoT is that every object can mine IoT in search for certain multimedia service. We investigate the issue of friends' management in SIoT and propose a framework to manage friends' requests. The proposed framework employs several mechanisms to better manage friends' relationships. The proposed framework consists of friend selection, friendship removal, and an update module. It proposes a weight-based algorithm and Naïve Bayes Classifier-based algorithm for the selection component. Moreover, a random service allocation model is proposed to construct service-specific network model. This model is then used in the simulation setup to examine the performance of different friends' management algorithms. The performance of the proposed framework is evaluated using simulation under different scenarios. The obtained simulation results show improvement over other strategies in terms of average degree of connections, average path length, local cluster coefficients, and throughput. 相似文献

The Internet of Things (IoT) is a paradigm aimed at connecting everyday objects to the internet. IoT applications include smart cities, healthcare, agriculture, as well as the industry and manufacturing. The ability to monitor and control the physical world using information technology creates many opportunities. However, it also comes with some costs. The exponential growth of connected devices, the heterogeneity of IoT use cases, and the diversity of the network technologies yield a concern regarding IoT sustainability. With this work, we aim to contribute to this concern. In doing so, we introduce a novel representation model that is destined for (i) monitoring the IoT environment at runtime, (ii) expressing the overall quality of the system, and (iii) helping to utilize the available resources efficiently. We also define a feature set that describes the best the expectations of decentralized IoT platforms. Furthermore, we describe a quality-enabled decentralized IoT architecture too that incorporates the specified feature set as well as our representation model. Such solutions are necessary to improve and maintain IoT of the future and all its application domains, including the Industrial Internet of Things (IIoT). With the presented research, we aim to encourage the efficient utilization of resources and simplify the production of next-generation IoT solutions. 相似文献

Internet of Things (IoT) has radically transformed the world; currently, every device can be connected to the Internet and provide valuable information for decision-making. In spite of the fast evolution of technologies accompanying the grow of IoT, we are still faced with the challenge of providing a service oriented architecture, which facilitates the inclusion of data coming together from several IoT devices, data delivery among a system's agents, real-time data processing and service provision to users. Furthermore, context-aware data processing and architectures still pose a challenge, in spite of being key requirements in order to get stronger IoT architectures. To face this challenge, we propose a COLLaborative ConText Aware Service Oriented Architecture (COLLECT), which facilitates both the integration of IoT heterogeneous domain context data — through the use of a light message broker — and easy data delivery among several agents and collaborative participants in the system — making use of an enterprise service bus —. In addition, this architecture provides real-time data processing thanks to the use of a complex event processing engine as well as services and intelligent decision-making procedures to users according to the needs of the domain in question. As a result, COLLECT has a great impact on context-aware decentralized and collaborative reasoning for IoT, promoting context-aware intelligent decision making in such scope. Since context-awareness is key for a wide range of recommender and intelligent systems, the presented novel solution improves decision making in a large number of fields where such systems require to promptly process a variety of ubiquitous collaborative and context-aware data. 相似文献

Smart technology is a concept for efficiently managing smart things such as vehicles, buildings, home appliances, healthcare systems and others, through the use of networks and the Internet. Smart architecture makes use of technologies such as the Internet of Things (IoT), fog computing, and cloud computing. The Smart Medical System (SMS), which is focused on communication networking and sensor devices, is one of the applications used in this architecture. In a smart medical system, a doctor uses cloud-based applications such as mobile devices, wireless body area networks, and other cloud-based apps to provide online therapy to patients. Consequently, with the advancement and growth of IoT and 6G wireless technology, privacy and security have emerged as two of the world’s most important issues. Recently, Sureshkumar et al. proposed an authentication scheme for medical wireless sensor networks (MWSN) by using an Elliptic Curve Cryptography (ECC) based lightweight authentication protocol and claimed that it provides better security for smart healthcare systems. This paper will demonstrate that this protocol is susceptible to attacks such as traceability, integrity contradiction, and de-synchronization with the complexity of one run of the protocol and a success probability of one. Furthermore, we also propose an ECC based authentication scheme called ECCbAS to address the Sureshkumar et al. protocol’s vulnerabilities and demonstrate its security using a variety of non-formal and formal methods. 相似文献

The paper proposes the use of Node-RED, a flow-based programming tool targeted to Internet of Things (IoT), along with a series of case studies related to different IoT contexts, which demonstrate Node-RED's potentialities and outcomings toward the realization of well-structured IoT environments. The analyzed applications potentially include a wide range of domains, ranging from smart cities, smart buildings, smart homes/offices, smart retailing, to smart transportation, smart logistics, smart agriculture, smart health, military scenarios, and so on. The motivations behind the presented work are related to the fact that IoT application fields usually involve the same technologies and communication protocols, which are frequently adopted for totally different purposes. Issues such as systems' interoperabiliy, scalability, security and privacy naturally emerge, due to the huge amount of heterogeneous devices acting in the IoT environment itself and to the wireless nature of information transmissions. As a consequence, it is fundamental to dispose of adequate tools for supporting developers in design the network architecture and messages' exchange, in order to realize efficient and effective IoT network infrastructures. 相似文献

Today, the Internet of Things (IOT) generally refers to a network with intelligent everyday objects ubiquitous. Things will be connected not only by humans but also by all items embedded systems highly distributed network of other devices. The integration of interactive communication devices has increased the popularity of the Internet. In recent years, the development and application of things have been a complicated task that requires extensive expertise. This is an essential issue for developers' experience, in particular, non-programmable skills, build rapid prototypes of things. To solve this problem, improved virtualization methods for IoT objects have been proposed. The proposed method uses the concept of virtual object existence, which allows end-users to create virtual items on top of them with simple operations such as dragging, then drop and click. Use various sensors and actuators and Intel Edison boards to implement virtual prototypes of IoT objects based on the Internet Engineering Task Force (IETF) CoAP protocol. Proposed items by connecting and visualizing components that support IoT virtualization methods and virtual objects of physical IoT devices. Therefore, virtual objects to access physical IoT devices. 相似文献
