摘要
随着"互联网+政务服务"深入推进,电子证照应用进入了快速建设期.在电子证照管理中,不同的业务需由专门的单位来完成,在传递过程中需要确认参与者的身份并且不能对外泄露.针对电子证照管理的业务特点,本文提出一种基于区块链的可信身份电子证照管理系统与访问控制方法.该方法基于模糊测度,采用多属性聚合算子,通过对用户属性进行聚类评价,从而对用户权限进行访问控制,建立用户权限校验证书和基于使用场景的证照加密,实现电子证照管理在区块链环境下的用户身份可信任、证照防篡改和隐私防泄漏.
Abstract
With the in-depth promotion of"Internet plus government services",the application of electronic licenses has entered a rapid construction period.In electronic certificate management,different businesses need to be completed by specialized units,and the identity of participants needs to be confirmed during the certificate transmission process.It cannot be disclosed to the public.This paper proposes a blockchain-based trusted identity electronic certificate management system and access control method.This method is based on fuzzy measurement and a multi-attribute aggregation operator.User permissions are controlled by clustering and evaluating user attributes.User permission verification certificates and certificate encryption based on usage scenarios are established,implemented electronic license management in a blockchain environment with user identity trustwor-thiness,license tamper prevention,and privacy leakage prevention.
