Securing Content Delivery and Provenance

SECOND extended the Named-Data Networking (NDN) implementation of the Information-Centric Networking (ICN) paradigm, using Decentralized Identifiers (DIDs) to support a self-sovereign, content authentication scheme.





Additional Info

The experiment used Verifiable Credentials (VCs) to support authorized network layer operations, and Zero-Knowledge Proofs (ZKPs) to support partial revelation of content. SECOND integrated DIDs and VCs into the core NDN functions, allowing it to secure content caching and forwarding, and enabled the binding of DIDs to human-readable content names, to simplify user interaction.
The latter was made possible after closely cooperating with the NDN experts at UofM and co-designing a solution that does not require any modifications to the NDN codebase. The collaboration consisted of (at least) monthly video conferences and a visit from one of the members of the AUEB Team to the UofM. The UofM will exploit the DID-based identification and ZKP-based selective disclosure schemes developed by SECOND for their NSF-funded secure vehicular data project.

Enduser Relevance

The Securing Content Delivery and Provenance (SECOND) project explored the full potential of Self-Verifiable Content (SVC) in Named Data Networking (NDN).
For end-users this improved SVC usability, content provenance and enhanced privacy.
