| Abstract (English): | When the Internet of Vehicle (loV) traditional access control is to provide safer road driving and efficient traffic management, it has problems such as the inability to dynamically authorize vehicle permissions, the inability to authorize resources in a fine-grained manner, and the difficulty of tracing 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. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): | 当下车联网访问控制通常是使用传统访问控制模型实现安全的道路行驶和高效的交通管理, 针对传统车联网访问控制存在无法动态授权车辆权限、对资源无法细粒度授权, 且难以对通信双方历史交流通信进行回溯等问题, 提出基于角色的访问控制 (RBAC) 与基于属性的访问控制 (ABAC) 相结合的混合访问控制模型 BARV-BAC。首先, 制定角色-属性规则、属性授权规则和访问控制策略。其次, 设计角色-属性智能合约 (Role publisher-SC) 和资源智能合约 (RE-SC), 以实现车联网动态化和细粒度管理。此外, 使用数字签名验证用户对该角色的所有权, 同时验证模型的可靠性。实验结果表明, 在所仿真的道路环境下, 模型的平均延迟小于200ms, 与传统访问控制模型相比有较大提升, 与其他访问控制模型相比智能合约开销减少明显, 进一步验证了BARV-BAC在车联网访问控制上具有高效性、实用性和安全性。 [ABSTRACT FROM AUTHOR] |
