【Abstract】The digitization of the national economy and the development of the national network have rapidly increased the amount of data, and research in content storage and forwarding is significant. The existing methods of storing certificates and distributing file content entirely rely on the judgment made by the router, and the forwarding process does not consider the security and legality of the data; at the same time, the traditional peer-to-peer (P2P) forwarding network files cannot be effectively reused, and additional security mechanisms are introduced. It affects the performance of the network itself. To improve the overall network performance, optimize the file forwarding process, and ensure the security of content and the verification of historical information, this paper proposes a method for document content storage and distribution that integrates blockchain technology and Named Data Network (NDN). The advantages of data signature encryption, reverse path forwarding of content, and flexible routing improves the overall performance of the forwarding network. Combined with blockchain decentralization technology, the documents and transaction processes can be stored on the chain to ensure the actual security of the forwarding process. In addition, this paper restricts the forwarding process in the NDN network without making any judgments through smart contract rules to ensure the security of confidential files during the forwarding process and, at the same time, limit the forwarding scope of irrelevant junk files in the private network. Finally, experiments prove that the method proposed in this paper can effectively improve the network's overall performance, optimize the forwarding process, and make rule judgments on the forwarding process of specific files to ensure the security of files.
