Trustworthiness Management in the Social Internet of Things Michele Nitti, Roberto Girau, and Luigi Atzori, Senior Member, IEEE Abstract—The integration of social networking concepts into the Internet of things has led to the Social Internet of Things (SIoT) paradigm, according to which objects are capable of establishing social relationships in an autonomous way with respect to their owners with the benefits of improving the network scalability in information/service discovery. Within this scenario, we focus on the problem of understanding how the information provided by members of the social IoT has to be processed so as to build a reliable system on the basis of the behavior of the objects. We define two models for trustworthiness management starting from the solutions proposed for P2P and social networks. In the subjective model each node computes the trustworthiness of its friends on the basis of its own experience and on the opinion of the friends in common with the potential service providers. In the objective model, the information about each node is distributed and stored making use of a distributed hash table structure so that any node can make use of the same information. Simulations show how the proposed models can effectively isolate almost any malicious nodes in the network at the expenses of an increase in the network traffic for feedback exchange.

Key component of the IoF is then the Internet of Service (IoS), which is aimed at making every possible service (from the management of the own house pantry to the management of the whole company production process) widely and easily available through the Internet yielding to higher productivity. Strictly linked to the IoS is the Internet of Things (IoT), which is aimed at embodying into the Internet a large number of objects that through standard communication protocols and unique addressing schemes provide services to the final users. IoT is then somehow a part of the IoS when the information provided by the objects are seen as services, which are specifically aimed at making information about the physical world available on the Internet [1]. A big value of the IoF resides on its ability to create powerful network of resources, i.e. in making resources social. Such social relationships would great facilitate the • The authors are with the Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari 09123, Italy.

To achieve this goal the IoF should be endowed with the ability to define, build, manage, and access social relationships between resources. Whereas this is currently a reality for the relationships among humans through the technologies for the social Web, still great efforts are needed for an effective management of the social relationships for the other types of resources with only high-level solutions appeared on the literature. In the IoT world, there are interesting papers that proposed the introduction of social relationships among objects. For instance, in [2] the authors introduce the idea of objects able to participate in conversations that were previously only available to humans. Analogously, the research activities reported in [3] consider that, being things involved into the network together with people, social networks can be built based on the Internet of Things and are meaningful to investigate the relations and evolution of objects in IoT. This has also brought to the convergence of IoT and social network paradigms, as analyzed in [4], which depicts the scenarios where an individual can share the services offered by her smart objects with her friends or their things through widespread social networks. In [5] and [6], explicitly, the Social IoT (SIoT) concept is formalized, which is intended as a social network where every node is an object capable of establishing social relationships with other things in an autonomous way according to rules set by the owner. This new paradigm is also stimulated by the concept that the many are smarter than the few [7], so that objects should interact intensely to converge to opinions and information supported by the crowd. Until now, in these proposals the focus has been directed to the definition of the relationships and interactions among objects and to the definition of reference architectures and 1041-4347 c 2013 IEEE.
