Abstract	In recent years, smart cities’ data have been affected by a lot of security problems. Protecting the smart cities’ data is a major problem in the development of smart cities. Therefore, the data is to be stored into the cloud. Because cloud computing is an emanating paradigm to distinguish the user’s data has to be stored into cloud server remotely. Cloud data service provides an extensible and convergent way for data shared across multiple users, which brings greater conveniences for the users. However, the users’ data are stored and shared with trustworthy cloud providers. It will raise a lot of security concerns. Attribute-based encryption (ABE) is a popular mathematical technique in the cloud storage system to resolve security concerns. In the new CP-ABE method, however, key escrow problem cannot be solved. A new Ciphertext Policy Attribute-Based Encryption with Key Hashing Scheme is implemented to overcome this problem. The mechanism’s key role avoids key escrow and reverses secrecy. Therefore, by analyzing security and performance, the proposed method allows for efficient and secure data sharing in cloud computing. © 2021, Springer Nature Switzerland AG.
