Internet of Things (IoT) is characterized by heterogeneous technologies, which concur to the provisioning of innovative services in various application domains. In this scenario, the satisfaction of security and privacy requirements plays a fundamental role. Such requirements include data confidentiality and authentication, access control within the IoT(More)
This paper discusses how information about the architecture and the vulnerabilities affecting a distributed system can be used to quantitatively assess the risk to which the system is exposed. Our approach to risk evaluation can be used to assess how much one should believe in system trustworthiness and to compare different solutions, providing a tool for(More)
End-to-end data aggregation, without degrading sensing accuracy, is a very relevant issue in Wireless Sensor Networks (WSN) that can prevent network congestion to occur. Moreover, privacy management requires that anonymity and data integrity are preserved in such networs. Unfortunately, no integrated solutions have been proposed so far, able to tackle both(More)
Nowadays Wireless Sensor Networks (WSN) are used in many application contexts. Data handled by WSN are required to be protected for privacy reasons since they can be directly or indirectly related to individuals. The problem of preventing the identification of individuals starting from their data, known as anonymity, is a fundamental requirement for privacy(More)
The ongoing revolution of Internet of Things (IoT), together with the growing diffusion of robots in many activities of every day life, makes IoT-aided robotics applications a tangible reality of our upcoming future. Accordingly, new advanced services, based on the interplay between robots and " things " , are being conceived in assisting humans.(More)
Wireless sensor networks (WSNs) in which the location of sensors is a key information are becoming more and more important. Moreover, in many cases privacy is a key issues for such network which can be the target of different kind of security attacks. In this paper we present an approach, named Cross Layer Protocol (CLP), for improving data quality based on(More)
