Resumen
Cost reduction and a vastly increased potential to create new services, such as via the proliferation of the Cloud, have led to many more players and ?end points?. With many of them being new entrants, possibly short-lived, the question of how to handle trust and privacy in this new context arises. In this paper, we specifically look at the underlying infrastructure that connects end-points served by these players, which is an essential part of the overall architecture to enable trust and privacy. We present an enhanced architecture that allows real people, objects and services to reliably interact via an infrastructure providing assured levels of trust.
