Abstract

To address the issues that traditional Internet of Vehicles (IoV) data is readily manipulated with and access control is inflexible, a security sharing method for IoV data is presented that utilizes blockchain technology and weighted cipher text policy attribute-based encryption. Maintain the production, verification, and storage of blocks, implement distributed data storage, and secure the integrity of data; access control of data on the chain based on characteristics to ensure that only authorized visitors may access data content; For the Internet of Vehicles data access, a multi-attribute-based hierarchical access policy formulation approach is built by mining the association relationship between points and permissions between roles. This method simplifies the complexity of access control policies. The built-in hierarchical access policy formulation approach efficiently reduces the computation and transmission overhead of cars while meeting the needs of the Internet of Vehicles scenario for access to various entities and different roles.
基于区块链的车联网安全数据传输
针对传统车联网数据易被篡改和访问控制不灵活的问题,提出了一种利用区块链技术和基于加权密文策略属性加密的车联网数据安全共享方法。维护区块的产生、验证、存储,实现数据的分布式存储,保障数据的完整性;根据特征对链上的数据进行访问控制,确保只有获得授权的访客才能访问数据内容;针对车联网数据访问,通过挖掘点之间的关联关系和角色之间的权限关系,构建了基于多属性的分层访问策略制定方法。这种方法简化了访问控制策略的复杂性。内置的分层访问策略制定方法在满足车联网场景对不同实体、不同角色访问需求的同时,有效降低了汽车的计算和传输开销。
