Securing private wireless sensors in a shared environment in the Internet of Things context

Abstract

To lead to the Smart Cities, we should have the possibility of obtaining information from different places and objects anytime and anywhere, in order to collect sufficient data to anticipate problems and take a good decisions. This will promote to an effective and autonomous organization by creating interacted and communicated objects around the city. So, we need to install various and specific IP-based wireless sensors everywhere to collect data remotely and in a real time. The idea of mixing sensors belonging to organizations from different specialties in the same places will involve several experts and encourages competition. But on the other side, it will open the door to new security threats and issues, also this will impose new management problems like how to limit the access to each organization to its sensors. In this paper, we study the security of a set of IP-based wireless sensors, which belongs to different organizations, and form a local network. We propose a model to ensure exchanged information confidentiality and manage the sensors accessibility, while considering the wireless sensors constrained characteristics.
