Secure and trustworthiness IoT systems: investigations and literature review

Internet of Things (IoT) is creating a new automated environment where human interaction is limited, in which smart-physical objects obtain the power to produce, acquire, and exchange data seamlessly. Hence, diverse IoT systems concentrate on automating various tasks. These automated applications and systems are highly promising to increase user satisfaction while also increasing security-related challenges. Accordingly, Security and Trust are critical elements for users' well-being. In this paper, we investigate the security and trust properties along with the focus on various existing novel technologies (Software-defined networking, Blockchain, and Artificial Intelligence) and provide a survey on the current literature advances towards secure and trustworthy IoT. Furthermore, we present a detailed study on various security and trust issues in various IoT environments. Moreover, we discuss real-life IoT-security projects, specify research challenges, and indicate future research trends.
