ABSTRACT
Named Data Networking (NDN) is expected to be the successor to the current host-based Internet. It includes a variety of improvements to network communication involving built-in multicast, in-network caching, multipath forwarding, and direct data security. Despite these overwhelming offers, NDN is exposed to several attacks, including content poisoning attacks from intruders, primarily the producers that stole the credentials of other authorised producers. These vulnerabilities lead to trust issues regarding the data received by the consumers. In the context of Industry 5.0, where the integration of advanced technologies with human skills and capabilities is emphasised, it becomes crucial to address these trust issues in NDN. Following the issue, this chapter presents an integrated trust-based consensus mechanism that will authenticate the producer's identity before the data they send is stored in cache memory on the NDN. It explores the integration of a blockchain consensus mechanism into NDN, namely the Proof-of-Trust. The mechanism enhances the NDN's trustworthiness, ensuring that the data consumers receive in Industry 5.0 systems is reliable and secure.
