Design And Implementation Of Industrial Internet Identifier Registration And Resolution System Based On DHT

In recent years,with the rapid development of 5g technology and the rise of a new round of industrial reform,a large number of emerging heterogeneous electronic devices are full of people's lives."Interconnection" has a new definition.The interconnection between traditional computer hosts has been expanded to the interconnection between any two machines,even the interconnection of everything.Human society has entered the era of industrial Internet.In addition,the concept of domain name resolution in the traditional Internet has also been applied to a broader field,completing the transformation from only websites have domain names to all things can be identified.The liberation of this concept makes all aspects of society more closely linked.However,the arrival of the industrial Internet era has brought great challenges to the traditional Internet.Whether from the infrastructure or the matching degree of industrial scenes,the disadvantages of the traditional Internet have gradually emerged.The single IP address has been unable to meet the high requirements of industrial manufacturing for refinement.At the same time,the security problems existing in the traditional Internet architecture no longer meet the needs of the industrial field.Therefore,the industrial Internet system came into being,which aims to make up for the shortcomings of the traditional Internet with a new system.From the functional composition,the industrial Internet system can be divided into four sub-systems,the most important is the identifier resolution system which provides core services,the rest also includes the network connection part as the infrastructure,the platform for external access,and the security system which provides security.As the provider of core services,the development of identity resolution system has a profound impact on the future of industrial Internet.It is not only the hub of the integration of various parts of the industrial Internet,but also the entrance for enterprises to access the industrial Internet.At present,many countries have made some research and development on the identity resolution system,and have derived many different identity resolution systems.According to the degree of dependence on the traditional Internet domain name resolution system,these systems can be divided into two categories:one is to rely on the improvement of the domain name resolution system,which has low security;the other is to completely get rid of the dependence on the domain name resolution system Relying on the development of a new analytical system,this kind of system adopts hierarchical design,which has the problem of service kidnapping.Therefore,in order to further develop the identity resolution system,it is necessary to start from the existing problems of these two kinds of systems.Only the organic combination of equivalence and security can open a new direction for the development of identity resolution system.Therefore,aiming at the existing problems of equivalence and security in identity resolution system,this paper proposes and implements an identity registration resolution system based on distributed hash table and blockchain.It is a new identity resolution architecture,which uses distributed hash table to solve the non-equivalence of hierarchical resolution in traditional domain name resolution,and uses emerging blockchain technology to solve the problem of system access Based on the two technologies,a complete process of identity registration and identity resolution is designed.In addition,aiming at the failure of the resolution node,this paper proposes a master-slave node memory synchronization scheme,and makes a complete implementation of this design.In the part of testing,the core functions of the system are tested and analyzed.
