Reputation-Based Blockchain for Secure NDN Caching in Vehicular Networks

Enormous research efforts have been investigated in Vehicular Ad Hoc Networking to improve users safety, traffic condition, and provide different reliable services, that are challenging tasks to accomplish in the current Internet model. In-network caching is one of the promising features of Named Data Networking, a new future Internet architecture based on content name instead of the host address. It aims to enhance the network performance, data availability, distribution, and access. The applicability of NDN in VANET introduced several issues, especially in the security and trust relationships. In this paper, we present a reputation-based blockchain mechanism to secure the cache in the vehicular environment and enhance the trust between cache stores and consumer vehicles. The obtained results demonstrate that our scheme outperforms the normal NDN behavior by providing only trust content in the network.
