基于区块链的去中心化多授权机构访问控制方法
Blockchain-based Decentralized Multi-authority Access Control Method
摘要
Abstract
The traditional access control scheme based on single authorization authority.To solve its sin-gle point of failure and inefficiency,a decentralized multi-authorization authority access control method was proposed based on blockchain.Firstly,The approach used the consortium blockchain based multi-au-thorization authorities to replace the centralized entity in traditional access control methods,which could provide reliable and fine-grained access control.Secondly,smart contract allowed automatic policy judg-ments,and to solve the access efficiency problem caused by multiple authorized institutions,a data map-ping algorithm based on smart contract was proposed to achieve fast access,which constructed a mapping table of key data information.Finally,experiments showed that the proposed scheme could effectively re-duce user access delay and realize secure sharing during data access.关键词
