      Preface

      With an enormous range of applications, Internet of Things (IoT) has magnetized industries and

      academics from everywhere. IoT facilitates communication and operations through Internet access to all the devices with computing capabilities. Many applications can be applied in IoT, such as intelligent transportation systems, real-time medical monitoring, intelligent appliances and intelligent agriculture, and the smart grid. Internet of Things (IoT) makes a smart communication process between objects and their environment over the internet. Security and privacy are two important aspects of IoT applications. Smart objects and machine-to-machine communications with complete data security are now a demand. Similarly, privacy is another major challenge of IoT applications where an object is free from interference from other objects. Trust based communication is one way to deal with these primary IoT based aspects. Internet of Things (IoT) creates a world where smart objects and services interact autonomously. Therefore, a central issue is whether the service provided by a selected IoT device is trustworthy. Further, most IoT devices are mobile and will connect to the Internet on and off, depending on the location they roam into as well as the energy status of individual IoT devices. Considering the dynamic-heterogeneous characteristic of interconnected devices in IoT, it demands an effective and efficient trust-based IoT communication system that can scale to many heterogeneous devices in IoT systems. In heterogeneous and complex environments, those resources must trust each other. On-Off attacks threaten the IoT trust security through nodes performing good and bad behaviours randomly to avoid being rated as a menace.

Security and privacy are two important aspects of IoT applications. Smart objects and machine-to-machine communications with complete data security are now a demand. Similarly, privacy is another major challenge of IoT applications where an object is free from interference from other objects. Trust based communication is one way to deal with these primary IoT based aspects. A trust-based communication system is needed to guarantee security, authentication, authorization, and confidentiality of connected things, regardless of their functionality because not all IoT devices will be trustworthy and some IoT devices may behave maliciously to disrupt the cloud service (e.g., an adversary) or just for their own gain (e.g., for increasing their chances to be selected to provide requested services). Furthermore, users who own IoT devices are likely to be socially connected via social networks. For participatory sensing IoT Applications, it is critical to assess source trustworthiness of IoT devices which report sensing results, so untrustworthy data can be filtered out before data analysis is taken.

      This book encompasses all aspects of research and development of secure IoT applications. It delivers technologies to improve trust and eliminate malicious actors in participatory exchanges throughout the communication using IoT devices ss that these methods are not only be able to identify bad actors, but also to improve communication and trust in the environment without violating object privacy. This book also covers a broad spectrum of applications in the community from industry, government, and academia. This book brings together thought leaders, researchers, industry practitioners, potential users of communication technology, and IoT device manufacturers to develop the field, discuss new trends and opportunities, exchange ideas and practices, and promote interdisciplinary and cross-domain collaborations.
