Towards secure and context-aware information lookup for the Internet of Things

The Internet of Things (IoT) is receiving more and more attention from the research community. The opportunities it creates for new services make it an intriguing technological step. Based on this paradigm, objects (things) become recognizable and gain intelligence by exchanging information with their environment or by having access to information aggregated by other objects. Huge amount of information is expected to be generated, raising at the same time significant concerns: the generated information has to be organized in a meaningful way that facilitates the development of a variety of applications, and it should be protected against unauthorized access. In this paper we design and implement an architecture for retrieving information in the IoT. In the proposed scheme, access control policies limit information retrieval and information is organized in such a way that facilitates the development of context aware services.
