Content is at the heart of next-generation Internet architectures such as Content-Centric Networking (CCN): Instead of routing location-based messages to end hosts, the network transmits location-independent, named content objects. Such data objects can (and are envisioned to) be cached in arbitrary network nodes. In this paper, the authors discuss several privacy attacks related to the ubiquitous presence of caching in CCN: Attackers can monitor access to specific content objects by other users connected to the same cache, they can discover the names of objects stored in the cache, and they can duplicate entire data flows from and to other users of the cache.
