The Future Internet that includes Real World Objects and the Internet of Things together with the more classic web pages will move communications from a node-centric organization to an information-centric network allowing new paradigm to take place. The 4WARD project initiated some works on the Future Internet. One of them is the creation of a Network of Information designed to enable more powerful semantic searches. In this paper, we propose a security solution for a model of information based on a semantic description and search of objects. The proposed solution takes into account both the access and the management of both objects and their descriptions.
