Several applications fall under the broad umbrella of Data Dissemination Systems (DDS), where providers and consumers of information rely on untrusted, or even unknown middle-men to disseminate and acquire data. This paper proposes a security architecture for a generic DDS by identifying a minimal Trusted Computing Base (TCB) for middle-men and leveraging the TCB to provide useful assurances regarding the operation of the DDS. A precise characterization of the TCB is provided as a set of simple functions that can be executed even inside a severely resource limited trustworthy boundary.
