一种基于区块链的物联网访问控制方案
An Access Control Scheme of Internet of Things Based on Blockchain
摘要
Abstract
The application of blockchain technology in the resource management field of the Internet of Things has received wide attention,and is committed to solve the single point of failure,privacy,trust and other problems of centralized resource storage and man-agement in the Internet of Things environment.By studying the underlying principles of blockchain technology,combining with existing research achievements and other data security technologies,a blockchain based and attribute based access control scheme for the Internet of Things is proposed.In order to balance resource security and transparency of access control processes,a dual chain decentralized access control model is proposed,which stores and manages resource metadata information and access control information separately,which is conducive to efficiently query the required information.In order to improve the speed of access control evaluation and permission verification,attributes are divided and static attribute tokens are proposed,as well as an access tree policy expression method that introduces polynomial function.Finally,the smart contract is used to implement access control.Simulation experiments show that as a dynamic and reliable access control scheme,it can effectively protect the privacy and security of resources.关键词
