Secure Personal Content Networking over Untrusted Devices

Abstract

Securely sharing and managing personal content is a challenging task in multi-device environments. In this paper, we design and implement a new platform called personal content networking (PCN). Our work is inspired by content-centric networking (CCN) because we aim to enable access to personal content using its name instead of its location. The unique challenge of PCN is to support secure file operations such as replication, updates, and access control over distributed untrusted devices. The primary contribution of this work is the design and implementation of a secure content management platform that supports secure updates, replications, and fine-grained content-centric access control of files. Furthermore, we demonstrate its feasibility through a prototype implementation on the CCNx skeleton.
