一种基于分布式密钥与BLS签名的跨域认证方案
A Cross Domain Authentication Scheme Based on Distributed Key and BLS Signature
摘要
Abstract
[Objective]In order to solve the problem of node identity authentication in the cross domain traceability system of industrial Internet,this paper proposes Dion,a cross domain authentica-tion scheme based on the distributed key,which aims to overcome the centralization and scal-ability problems of the certificate authority in the current cross domain authentication scheme.[Methods]Based on the DID decentralized identity technology,this study uses the distributed key generation technology and BLS signature algorithm to build a certificate issuance model,establishes the revocation and update mechanism of user identity certificate through the con-tract,and uses the certificate to realize cross domain traceability identity authentication.[Re-sults]Experiments on the Ethereum platform simulated the application of the scheme in the cross-domain trace-ability authentication process.The results show that the scheme realizes the decentralization of the certification authority on the premise of meeting the authentication requirements of cross domain traceability of the industrial Internet,and enhances the system's resistance to the single point of failure.[Conclusions]The DID-based authen-tication model shows significant potential and application prospects in the field of blockchain technology and pro-vides effective authentication for the interaction between nodes.However,further research is needed in the as-pects of authentication efficiency,identity update,and revocation.关键词
