Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The name-based trust mechanism scheme design mainly lies in two aspects: one is to verify the integrity of data, and the other is to quickly obtain trust. The data producer calls the signature algorithm provided by the information service entity to sign the data packet. After receiving the data packet, the data requester first calls the verification signature algorithm provided by the information service entity to verify the integrity of the data, and then authenticates the identity of the data producer , if the data producer comes from a legitimate domain, the data requester trusts the data...

Abstract

The invention discloses a name-based trust method in a named data network. The method comprises the following steps: identity authentication based on a block chain technology: a domain-level information service entity applying for registration to a block chain and creates a block, and the block comprising a domain name, a public key of the domain and public parameter information of the domain; after receiving the data packet, the user verifying the identity of the domain where the producer of the data packet is located by adopting a domain-level identity authentication method, the data packetbeing credible if the verification succeeds, and otherwise, discarding the data packet; judging data credibility: signing each data packet, and a receiver judging the integrity of the data packet by verifying the data signature; according to the domain-level identity authentication method, determining the identity of a producer, and if the data packet has integrity and is generated by the producerwith legal identity, a receiver trusting the data packet. The domain-level identity is authenticated by adopting the block chain technology, the authentication efficiency is high and accurate, and the credibility of the data packet is judged by utilizing the identity authentication scheme.

Description

technical field [0001] The invention relates to the research field of named data network infrastructure, in particular to a name-based trust method in the named data network. Background technique [0002] With the advancement and development of technology, the cost of computers has gradually decreased, and more ordinary people have computers. The application of the Internet is no longer limited to the use of certain supercomputer services. With the improvement of people's living standards and continuous changes in needs, The scope of application of the Internet is increasing, such as e-commerce and online news broadcasting. Some offline sales stores and traditional media have been greatly impacted. Internet information dissemination is fast, which is conducive to the timeliness of news. With the rapid development of the Internet, people pay more attention to the content on the Internet rather than the location of the content. The current Internet cannot meet the needs of pe...
