An Efficient TCB for a Generic Content Distribution System

We consider the security requirements for a broad class of content distribution systems where the content distribution infrastructure is required to strictly abide by access control policies prescribed by owners of content. We propose a security solution that identifies a minimal trusted computing base (TCB) for a content distribution infrastructure, and leverages the TCB to provide all desired assurances regarding the operation of the infrastructure. It is assumed that the contents and access control policies associated with contents are dynamic.
