| Abstract |
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. |
