Zusammenfassung:

Traditionally manufacturers have treated device introduction and direct 
device-to-device authentication as afterthoughts, if at all. Mobility, ad hoc 
networking, meshes, ubiquitous computing, and other unmanaged networks have 
given urgency to the consideration of first class features to address these 
problems. In this talk, we examine reasons why the centralized authentication 
systems fall short for these new classes of networks and suggest some 
foundations for a distributed trust model to address these issues. We argue that instead of a simple label, an identity signifies a relationship the named entity has with the community. We describe a PGP-like paradigm in which every member can serve as a root to enroll and authenticate devices for the community. 
Members of the community share certificates they issue with each other, as well as other evidence relevant to identification. We illustrate our ideas with a technique we call identity laundering, to introduce device using existing relationships in other communities.
