The Internet of Things has presented a rapid development, due to the over-crowding of hardware and software platforms, greater deployment of communications networks, development of data analysis tools, among others. This development has led to a boom in applications focused on areas as varied as Smart Cities, Smart Agro, Smart Buildings, Smart Home, and Smart Health, in which people and things are interconnected. This is one of the reasons by which a review of the main technologies involved in the emergence of the Internet of Things must be carried out to determine those characteristics allowing that interconnection, but without neglecting security. This issue allows the user to feel con dent to use these new services. In this work, we propose a cross-device architecture that integrates technologies and implementations in homes, and uses basic authentication as a security scheme. To validate the cross-device proposal, a case study scenario has been designed, including and integrating digital-TV (DTV), Smart Phones and wearables devices for monitoring users physical activity.
