FoTSeC - Human Security in Fog of Things

Today's devices, which make up the Internet of Things (IoT) and Cyber-Physical Systems (CPS), are becoming increasingly more heterogeneous, mobile and intelligent. They represent an untapped computational resource that is available on site. By taking advantage of these devices we reduce the need for distant service providers: direct communication with neighbour devices becomes key for handling local tasks and information. Thus, the traditional cloud is descending to the network edge and becoming diffused among the client devices in both mobile and wired networks. Since single individuals are now becoming walking sensor networks, with many types of devices (smart-shirts, smartphones, smart glasses, smart watches.), human behavior begins to have a significant impact on the availability of resources. This means that security risks rise tremendously in these distributed clouds. The objective of this paper is to present an analysis of security in the future Internet - an Internet that integrates the concepts of Fog of Things (FoT) and Human in the Loop (HiTL). This paper also describes our model and the platform that we implemented for the evaluation tests. In this paper we anticipate the future by discussing a new generation of security and privacy mechanisms targeting specifically: 1) a layer of virtual devices that implements new security and privacy solutions while hiding all of the underground heterogeneity, distribution of resources and mobility. 2) Human in the Loop awareness using all of the available devices to understand the behavior of both individuals and crowds. Since humans are becoming an integral part of CPSs, it is of the utmost importance to implement security and privacy mechanisms that takes into account human factors.
