Abstract

Internet of Things has been a most important research area for almost a decade now, where a huge network of billions or trillions of “things” communicating with one another is facing many technical and application challenges. Although there are many uncertainties about its security and privacy, the literature presents different techniques to handle the security issues and challenges in order to develop a well-defined security architecture. This paper reviews 50 research papers that are related to the security of IoT. The security techniques were classified with respect to time consumption, energy consumption, power consumption, lightweight property, reliability, robustness, and smart applicability. Also, the security techniques were analyzed based on the considered attacks, application, utilized simulation tool, security model, and attributes. The objective of the survey is focused on the security loopholes arising out of the information exchange technologies used in IoT. Finally, the important research issues are addressed for the researchers to find the way for further research in the security of IoT. The survey signifies that multilevel and mutual authentication based on attribute-based profile modeling bring more security for access control and authentication.
