Personal data is assumed to become the "energy" or the "new currency" for digital world. Currently personal data potentiality is not fully exploited due to "organization-centric" approaches in the management of personal data. This paper presents a "user-centric" model, which aims at unlocking such potentiality, by enabling individuals to control the gathering, management, use and sharing of data about them. In particular, the paper analyses a new personal data ecosystem centered around the role of "Bank of Individuals' Data" (BID), a provider of "personal data management services" enabling people to exploit their personal data. We call this role Bank as it manages data as commercial banks manage money. Finally, it discusses challenges and opportunities for Telcos to become a BID.

Internet of Things (IoT) nodes participating in the implementation of next‐generation IoT applications will need standard methods to authenticate each other and secure their communications. However, the use of certificates and public key infrastructure (PKI) technologies, widely employed in the Internet, is not straightforward in this context because of the limitations of the involved entities. This paper presents the public key infrastructure for the Internet of Things (PKIoT) architecture, a solution which aims at enabling certificate‐based authentication in the forthcoming IoT scenarios by allowing the flexible outsourcing of the most demanding security‐related tasks and by introducing a new type of compact certificate. This paper also highlights the role that this architecture can play in the context of the oneM2 M security framework in enabling standard secure machine‐2‐machine interactions. In conclusion, this paper reports the results of the conducted experiments, which show the effectiveness of the proposed approach in reducing the execution time and the energy consumption of certificate‐based session establishment for Datagram Transport Layer Security up to 78% and 89% respectively, fostering this way standard and secure IoT transactions.

In this paper we describe R-P2P, a novel system meant to support the search and retrieval of data in a certain location. R-P2P couples opportunistic wireless communications between mobile devices with an interconnected network of throwboxes. The set of throwboxes implements a distributed and localized data storage.Overall, the system integrates in an on-demand, delaytolerant fashion two main network extensions: a query forwarding engine running on top of the opportunistic network and a data retrieval mechanism performed on throwboxes.We detail the building blocks of the proposed system, describing the functionalities and the interactions of the various middleware modules. Finally, we illustrate the current implementation of R-P2P.

One of the most challenging objectives of the Internet of Things (IoT) domain is the identification of interaction paradigms and communication standards to integrate smart objects (SOs), i.e., physical objects able to interact with the network. Such interaction paradigms and communication protocols belong to what can be called the IoT application layer, on which this paper focuses. This paper presents app execution platform (AEP), a platform that supports the design, deployment, execution, and management of IoT applications in the domain of smart home, smart car, and smart city. AEP was designed to coherently fulfill a set of requirements covered only partially or in a fragmented way by other IoT application platforms. AEP focuses on SO virtualization and on composite application (CA) orchestration and supports dynamic object availability
