车联网环境下基于智能合约的混合访问控制模型
A hybrid access control model based on smart contract for the Internet of Vehicle environment
摘要
Abstract
When the Internet of Vehicle(IoV)traditional access control is to provide safer road driv-ing and efficient traffic management,it has problems such as the inability to dynamically authorize vehi-cle permissions,the inability to authorize resources in a fine-grained manner,and the difficulty of trac-ing the historical communication between the two communication parties.To solve these problems,a hybrid access control model(BARV-BAC)combining role-based access control(RBAC)and attribute-based access control(ABAC)is proposed.Firstly,role-attribute rules,attribute authorization rules and access control policies are established.Secondly,role publisher smart contract(Role publisher-SC)and resource smart contract(RE-SC)are designed to achieve dynamic and fine-grained management of IoV.In addition,a digital signature is used to verify the ownership of the role and verify the reliability of the model.The experimental results show that in the simulated road environment,the average delay of the model is less than 200 ms,which is greatly improved compared with the traditional access control models,and the smart contract cost is significantly reduced compared with other access control models.It is further verified that BARV-BAC has high efficiency,practicability and security in vehicle network access control.关键词
