The Desigh And Impletation Of Authenticated Registration And Trusted Resolution Mechanism For The Identity Resolution Of Iiot

With the explosive growth of the industrial machines access,the current global information technology is leading a new round of industrial informing,the future network will be transformed from consumption-oriented network to production-oriented network,then the concept of industrial Internet of things came into being.Moreover,the identity resolution system is the entrance to the industrial Internet of things,also the foundation of the whole industry Internet connectivity.Identity resolution system is connected with the factory machinery manufacturing equipment and raw materials for production.It is the key link between the information of industrial entity and human.At the same time,the research and development of identity resolution platform has been paid more attention.The future trillion-level industrial entity connection,information explosion growth,dynamic equipments and other issues will bring great challenges for the development of the current identity resolution system of the industrial Internet of things.Currently,there are variety of identity resolution systems applicable to the industrial Internet of things in the world.They can be divided into improvement path and innovation path according to the solutions.The improved path based on Domain Name System(DNS)represented by Object Identifier(OID)and Electronic Product Code(Ecode)system is highly dependent on DNS service,which has security risks such as single point failure,heavy load,root node hijack,etc.,and has natural defects in query delay and service stability.The innovation path represented by Handle system,though different from DNS,adopt a partially parallel architecture,is still fundamentally a hierarchical architecture,the root node failure,the security risks of unequal power still exists.Industrial manufacturing needs to have an efficient,safe and reliable identity resolution system to do support assignment.Therefore,in view of the above existing identity resolution system's security bottleneck problems,thus put forward an innovative identity resolution system architecture by using blockchain,distributed hash and other technologies.The architecture adopts DHT(Distributed Hash Table)technology to conduct peer-to-peer flat Distributed networking,so as to realize efficient storage and parsing of identities between nodes.This paper based on the innovative identity resolution system architecture,then the authenticated registration and trusted resolution mechanism of the identity resolution of IIoT is proposed around the security risk problems existing in the current identity resolution of IIoT.In view of the process of enterprise node access,enterprise user registration,update and identity resolution,the system module information interaction rules and identity authentication methods are designed.In addition,tamper-proof verification is carried out for the result of identification mapping data to further enhance the data security of the innovative identity resolution system.In terms of engineering implementation,the mechanism proposed in this paper combines the tamper-proof,distributed and other security features provided by blockchain technology.Then we build up the Hyperledger Fabric platform,use the CouchDB database to store authentication identification and trusted resolution information.Then we develop Java application to invoke the network forming function and the smart contract of blockchain.Then we develop the control subsystem module by combining the RSA algorithm and message digest algorithm.Through the above work,the innovative identity resolution system can provide new node joining,multi-level identity authentication,data tamper-proofing and other security services.At last,this paper carried out the basic function test of the proposed mechanism.The result shows that the proposed mechanism can effectively provide the above security enhancement services.
