With the development of informatization, smart city has become a new concept for the next generation of urbanization globally. In the face of intensive data requests and constrained resources, it is particularly important to design a safe and energy-efficient computing system.In this paper, we propose a multi-domain access control scheme suitable for smart city construction. We divide the huge equipment group into multiple domains for parallel distributed management to improve data processing efficiency. Based on attribute mapping, we show a safe and efficient cross-domain access control method. We introduce a trusted third-party (TTP) and an attribute mapping center (MC), using attribute certificates, digital mapping tables, B+ tree index, and buffer to improve mapping efficiency. In the complex one-to-many data transmission process, the outsourced ciphertext-policy attribute-based encryption (CP-ABE) is used to provide users with personalized services while reducing the computing burden. Finally, through analysis and simulation, it is found that this scheme has higher safety and efficiency.

基于可信第三方和属性映射中心的跨域访问控制

随着信息化的发展,智慧城市已成为全球下一代城市化的新概念。面对大量的数据请求和有限的资源,设计一个安全,节能的计算系统尤为重要。本文提出了一种适用于智慧城市建设的多域访问控制方案。我们将庞大的设备组划分为多个域,以进行并行分布式管理,以提高数据处理效率。基于属性映射,我们展示了一种安全有效的跨域访问控制方法。我们使用属性证书,数字映射表,B +树索引和缓冲区来引入可信第三方(TTP)和属性映射中心(MC),以提高映射效率。在复杂的一对多数据传输过程中,外包的基于密文策略的基于属性的加密(CP-ABE)用于为用户提供个性化服务,同时减轻计算负担。最后,通过分析和仿真,发现该方案具有较高的安全性和效率。
