Survey on security in Internet of Things: State of the art and challenges

The Internet of Things (IoT) refers to the physical devices that are embedded with Internet, electronics, software, sensors, actuators, and network connectivity. This includes many different systems, for instance, healthcare, wellbeing, smart home, building, smart meters, and so on. The Internet-based technical architecture, IP-based communication protocols, and technologies are facilitating the exchange of smart object services over the insecure channels, therefore, security and privacy of the involved stakeholder is the prime concern. In this paper we analyse available IoT security in three forms: (i) security in communication, (ii) security at application interface, and (iii) data security. This paper reviews the current IoT technologies, approaches and models and finds the security gap in existing communication technologies, application interfaces, and data security. Another focus of the paper is to provide an overview of the related work in IoT, together with the open challenges and future research directions me”.
