Blockchain-based Network Identity Management Mechanism

The rapid development of the Internet has affected all aspects of people,people's life and work all the time use the network identity.At the same time,while enjoying a high degree of information,the security of the network is also facing a variety of challenges.For users,many accounts and passwords make users face the problems of password fatigue,password reuse,centralized plug-in and so on.In the traditional network identity authentication mechanism,each server is relatively isolated,and the security protection appears the problem of the wooden barrel.In the intermingled state of network security,weak security protection has become a breakthrough for network attackers.In view of the problem of isolated communication islands,the credibility of communication credentials is still insufficient,which can not provide effective insurance services for the network identity of users and reduce the loss of users.As online identity has more and more real property value,online identity has become one of the important properties,and how to inherit effectively has great research significance.Aiming at the above problems of network identity,this paper proposes a network identity management mechanism based on blockchain.In this mechanism,there are three mechanisms,namely network identity authentication based on block chain,insurance and inheritance mechanism.The main contributions of this paper are as follows:(1)the proposed decentralized password manager,in compatible with the traditional solution for the user password fatigue,under the premise of code reuse,and other functions,and as a light node block chain,create a radio network identity,point-to-point interaction directly with block chain system,solved the problems of centralized plug-ins and server password manager,improved the password manager credible capricious.(2)combined with password manager account password management functions,is proposed based on block chain network login authentication mechanism,using the block chain point-to-point interaction,distributed storage,decentralized consensus etc,to solve the network security of barrel,improve the overall safety level of the network identity authentication and user identity credible capricious operation records.(3)Put forward the identity insurance mechanism based on blockchain network,combined with the function of smart contract,which can deal with the problems such as the difficulty of claim discrimination,the lack of credential trust,the complicated process,and the long time,so as to ensure the credibility and immutability of the user's identity operation record and realize automatic claim settlement.(4)A network identity inheritance mechanism based on block chain is proposed to fill the gap in the field of network identity inheritance.The information of the client is distributed stored in the blockchain distributed ledger through the decentralized consensus of the whole node of the decentralized server,which ensures the decentralization of the information and improves the trustability and security of the information.The decentralized execution of proof logic of the entrusting agreement by smart contract is used to realize the purpose of decentralized proof and improve the reliability of inheriting the entrusting information.The inheritor automatically verifies and obtains the information of the consignee through the smart contract,which improves the operability and efficiency in the network identity inheritance.
