In the envisioned Internet of Things ecosystems, Smart objects are intended to create groups of devices in order to provide higher level services to be leveraged by citizens. However, because of the dynamic nature of such scenarios, the discovery, management and operation of such dynamic coalitions taking into account security and privacy concerns, is a challenging task that has not been properly...
The IoT is intended to compose a global network of heterogeneous devices exchanging information in a constant and transparent way. In these scenarios, it is crucial the application of flexible data sharing mechanisms, adapted to the requirements of such environments, while security and privacy are preserved. In order to address these issues, this work analyzes a group sharing approach based on the...
Pervasive computing is becoming a reality due to the rise of the so-called Internet of Things (IoT). In this paradigm, everyday and physical objects are being equipped with capabilities to detect and communicate information they receive from their environment, turning them into smart objects. However, such entities are usually deployed on environments with changing and dynamic conditions, which can...
The increasing development of IoT is dramatically changing the way people share information and communicate with their surrounding environment, enabling a constant, invisible and sometimes unintended data exchange, between things and people. This extension of the current Internet to everyday life scenarios leads identity management has to face new challenges due to the inherent nature and requirements...
The strong development of the Internet of Things (IoT) is dramatically changing traditional perceptions of the current Internet towards an integrated vision of smart objects interacting with each other. While in recent years many technological challenges have already been solved through the extension and adaptation of wireless technologies, security and privacy still remain as the main barriers for...
