The Internet of Things (IoT) shall be able to incorporate transparently and seamlessly a large number of different and heterogeneous end systems, while providing open access to selected subsets of data for the development of a plethora of digital services. Building a general architecture for the IoT is hence a very complex task, mainly because of the extremely large variety of devices, link layer technologies, and services that may be involved in such a system. In this paper, we focus specifically to an urban IoT system that, while still being quite a broad category, are characterized by their specific application domain. Urban IoTs, in fact, are designed to support the Smart City vision, which aims at exploiting the most advanced communication technologies to support added-value services for the administration of the city and for the citizens. This paper hence provides a comprehensive survey of the enabling technologies, protocols, and architecture for an urban IoT. Furthermore, the paper will present and discuss the technical solutions and best-practice guidelines adopted in the Padova Smart City project, a proof-of-concept deployment of an IoT island in the city of Padova, Italy, performed in collaboration with the city municipality.

Security, privacy and trust in Internet of Things

A survey on trust management for Internet of Things

Internet of Things security

The world population is growing at a rapid pace. Towns and cities are accommodating half of the world's population thereby creating tremendous pressure on every aspect of urban living. Cities are known to have large concentration of resources and facilities. Such environments attract people from rural areas. However, unprecedented attraction has now become an overwhelming issue for city governance and politics. The enormous pressure towards efficient city management has triggered various Smart City initiatives by both government and private sector businesses to invest in information and communication technologies to find sustainable solutions to the growing issues. The Internet of Things IoT has also gained significant attention over the past decade. IoT envisions to connect billions of sensors to the Internet and expects to use them for efficient and effective resource management in Smart Cities. Today, infrastructure, platforms and software applications are offered as services using cloud technologies. In this paper, we explore the concept of sensing as a service and how it fits with the IoT. Our objective is to investigate the concept of sensing as a service model in technological, economical and social perspectives and identify the major open challenges and issues.

Trust management system design for the Internet of Things: A context-aware and multi-service approach

Building the Internet of Things requires deploying a huge number of objects with full or limited connectivity to the Internet. Given that these objects are exposed to attackers and generally not secured-by-design, it is essential to be able to update them, to patch their vulnerabilities and to prevent hackers from enrolling them into botnets. Ideally, the update infrastructure should implement the CIA triad properties, i.e., confidentiality, integrity and availability. In this work, we investigate how the use of a blockchain infrastructure can meet these requirements, with a focus on availability. In addition, we propose a peer-to-peer mechanism, to spread updates between objects that have limited access to the Internet. Finally, we give an overview of our ongoing prototype implementation.

Towards Better Availability and Accountability for IoT Updates by Means of a Blockchain

A method and apparatus are provided for establishing internet protocol (IP) communication with a node in an aggregation of one or more mobile networks each having a name server. The method includes multicasting ( 105 ) at least one message to the mobile networks indicating a name resolution of at least one mobile network in the aggregation, and determining ( 110 ) an IP address of the node from the name resolution(s) indicated by the multicasted message(s). The name resolution is based on a domain name of the name server of a corresponding mobile network in the aggregation.

In this paper we discuss security procedures for constrained IoT devices We start with the description of a general security architecture along with its basic procedures, then discuss how its elements interact with the constrained communication stack and explore pros and cons of popular security approaches at various layers of the ISO/OSI model We also discuss a practical example for the establishment of end-to-end secure channels between constrained and unconstrained devices The proposed method is lightweight and allows the protection of IoT devices through strong encryption and authentication means, so that constrained devices can benefit from the same security functionalities that are typical of unconstrained domains, without however having to execute computationally intensive operations To make this possible, we advocate using trusted unconstrained nodes for the offloading of computationally intensive tasks Moreover, our design does not require any modifications to the protocol stacks of unconstrained nodes
