        <s:content>1 Research Field &quot;Security, Trust, and Provenance&quot;&#xD;&#xA;&#xD;&#xA;There is a general lack of mechanisms to trace results and infrastructures to build up trusted networks, specially for distributed and open systems. Provenance enables users to trace how a particular result has been obtained by identifying the chain of transformation that it has undergone. A number of research questions and initiatives aim to produce new trust models and reputation mechanisms, to identify the provenance and quality of resources and services. These research efforts are also related to issues on interaction, security, scalability, semantic. &#xD;&#xA;&#xD;&#xA;1.1 Related Projects&#xD;&#xA;&#xD;&#xA;- [GRASP]&#xD;&#xA;</s:content>
