Hybrid Chain Based Hierarchical Name Resolution Service in Named Data Network

摘要

Named Data Networking (NDN) is a promising framework which advocates ubiquitous in-network caching to enhance content delivery. The framework provides mechanisms for users to request content restricted by public key of its source or the cryptographic digest of the content object to avoid receiving fake content. However, it does not provide any mechanisms to learn this critical information. Blockchain is a distributed ledger technology which could supply enhanced security, easy extensibility and scriptable programma-bility. Till now, the technology has attracted lots of attentions in network management research. However, each type of blockchain has its drawbacks, which could hurt the efficiency or credibility of system. This paper combines different types of blockchain, leverages a hybrid chain based Hierarchical Name Resolution Service (HNRS) for NDN. The design could provide a credible, efficient, flexible HNRS for NDN, thus supply an important support for NDN to build a credible, efficient, flexible benign ecological environment.
