Method and system of CCN trusted addressing based on DNS and extension protocol thereof

Abstract

The invention relates to a method and a system of CCN (Content-Centric Networking) trusted addressing based on a DNS (Domain Name System) and an extension protocol thereof. The method comprises the steps of deploying content management anchor points in every regions of the content-centric networking (CCN) and registering the content management anchor points in the DNS based on the content prefixes of all the regions, next, carrying out addressing in a hop-by-hop addressing manner and a centralized DNS addressing manner in the content-centric networking, establishing a complete trust chain by virtue of a DNSSEC (Domain Name System Security Extensions) protocol to provide security guarantee in the name resolution process, providing public key information verification by virtue of a DANE (DNA-Based Authentication of Named Entities) protocol and then realizing trusted verification on contents and finally obtaining the desired contents. The method and the system have the advantages that the existing base facilities of the current internet are well combined and a data management model capable of supporting future mass services is provided, and especially for the deployment of the future CCN in the mobile internet, the dynamic content management can be effectively supported and the flexible and efficient mass content addressing process can be realized.

Description

technical field [0001] The invention belongs to the field of network technology, and relates to a content-centric network (Content-Centric Networking, CCN) trusted addressing method based on DNS and its extended protocol, and a system using the method. Background technique [0002] With the rapid development of information technology, new Internet applications emerge in an endless stream, causing traditional IP technology to face many challenges. In particular, the rapid development of mobile communication technology and the emergence of emerging data applications such as the Internet of Things and cloud computing are gradually changing the traditional mode of Internet users' access to service resources, making the Internet gradually develop from the basic functions of interconnection to supporting massive data interaction. , and pose new challenges to network security and efficient mobility. [0003] In recent years, researchers have used many methods and means to improve ...

AI Technical Summary

Problems solved by technology

[0020] As mentioned above, although Content-Centric Networking (CCN) can solve the problems of routing scalability and data distribution efficiency to a certain extent, it does not propose a data management model that can support future massive services, especially It is to consider how to effectively support dynamic content management when CCN is deployed in the mobile Internet in the future; in addition, CCN lacks effective border management, which may cause huge overhead in the content addressing process, and the addressing process of CCN is not very effective. Well combined with the existing Internet infrastructure, it cannot well support its smooth evolution
