Manifest-Based Access Control Framework for Information-Centric Networking

This paper proposes a comprehensive encryption- based access control framework for content centric networking (CCN), called CCN-AC. This framework is both flexible and extensible, enabling the specification, implementation, and en- forcement of a variety of access control policies for sensitive content in the network. The design of CCN-AC heavily relies on the concept of secure content object manifests and leverages them to decouple encrypted content from access policy and spec- ifications for minimum communication overhead and maximum utilization of in-network caches. To demonstrate the flexibility of framework, we also describe how to implement two sample access control schemes, group-based access control and broadcast access control, within CCN-AC framework
