A personal network (PN) should enable the collaboration of user{\textquoteright}s devices and services in a flexible, self-organizing and friendly manner. For such purpose, the PN must securely accommodate heterogeneous technologies with uneven computational and communication resources. In particular, personal RFID tags can enable seamless recognition of user{\textquoteright}s context, provide user authentication and enable novel services enhancing the quality and quantity of data handled by the PN. However, the highly constrained features of common RFID tags and their passive role in the network highlights the need of an adequate secure communication model with personal tags which enables their participation as a member of the PN. In this paper, we present our concept of PN, with special emphasis on the role of RFID and sensor networks, and define a secure architecture for PNs including methods for the secure access to context-aware technologies from both local PN members and the Internet of Things. The PN architecture is designed to support differentiated security mechanisms to maximize the level of security for each type of personal device. Furthermore, we analyze which security solutions available in the literature can be adapted for our architecture, as well as the challenges and security mechanisms still necessary in the secure integration of personal tags.

The secure integration of RFID technology into the personal network paradigm, as a context-aware technology which complements body sensor networks, would provide notable benefits to applications and potential services of the PN. RFID security as an independent technology is reaching an adequate maturity level thanks to research in recent years; however, its integration into the PN model, interaction with other network resources, remote users and service providers requires a specific security analysis and a PN architecture prepared to support these resource-constrained pervasive technologies. This paper provides such PN architecture and analysis. Aspects such as the management of personal tags as members of the PN, the authentication and secure communication of PN nodes and remote users with the context-aware technologies, and the enforcement of security and privacy policies are discussed in the architecture.

El paradigma de red personal (PN) permitir\á la interacci\ón y colaboraci\ón del creciente abanico de dispositivos personales. Con tal fin la PN ha de integrar en su seno m\últiples tecnolog\ías heterog\éneas con diversas capacidades computacionales y de comunicaci\ón de forma segura. En particular, la incorporaci\ón de la tecnolog\ía RFID en objetos personales conlleva m\últiples riesgos de seguridad y privacidad que han suscitado un elevado inter\és de la comunidad investigadora en los \últimos a\ños. M\ás all\á de su seguridad de forma aislada, su integraci\ón en la PN y la interacci\ón de \ésta con redes de \área extensa como Internet of Things requieren una arquitectura de red personal adecuada para tal contexto. Este art\ículo proporciona los fundamentos de tal arquitectura segura incluyendo el an\álisis de aspectos como la incorporaci\ón e inicializaci\ón de las restringidas etiquetas RFID en la red personal, la autenticaci\ón tanto de miembros de la PN como de usuarios y servicios remotos en su acceso a las tecnolog\ías de contexto, el control de las pol\íticas de privacidad y el establecimiento de canales seguros de comunicaci\ón supervisados.

This paper presents security of Internet of things. In the Internet of Things vision, every physical object has a virtual component that can produce and consume services Such extreme interconnection will bring unprecedented convenience and economy, but it will also require novel approaches to ensure its safe and ethical use. The Internet and its users are already under continual attack, and a growing economy-replete with business models that undermine the Internet{\textquoteright}s ethical use-is fully focused on exploiting the current version{\textquoteright}s foundational weaknesses.
