On the Security and Privacy of Internet of Things Architectures and Systems

The Internet of Things (IoT) brings together a multitude of technologies, with a vision of creating an interconnected world. This will benefit both corporations as well as the end-users. However, a plethora of security and privacy challengesneed to be addressed for the IoT to be fully realized. In thispaper, we identify and discuss the properties that constitutethe uniqueness of the IoT in terms of the upcoming securityand privacy challenges. Furthermore, we construct requirementsinduced by the aforementioned properties. We survey the fourmost dominant IoT architectures and analyze their securityand privacy components with respect to the requirements. Ouranalysis shows a mediocre coverage of security and privacyrequirements. Finally, through our survey we identify a number ofresearch gaps that constitute the steps ahead for future research.
