Cloud Storage That Makes Use Of A Feature-Based Encoding Hierarchy To Maximize Efficiency

Abstract

Sharing data securely in the cloud is a major difficulty, but cipher text-policy attribute-based encryption has emerged as a top tool for meeting this need. The shared data files used in many different professions, including medicine and the military, have a multi-tiered, intricate structure. The file-sharing structure, however, has not been studied in cipher text-policy attribute-based encryption. Here, we provide a novel cloud-based encryption approach that takes advantage of hierarchies of file attributes. Before encrypting a folder tree, it is common practice to merge the various access controls into a single control scheme. Some components of the encryption text that pertain to attributes might be reused between files. The time and money needed to store encrypted documents and conduct encryption are therefore minimized. Finally, it is demonstrated that the proposed method is safe under the null hypothesis. In experimental simulations of encryption and decryption, the proposed method has been proven to be exceedingly efficient. Our method's advantages become more evident as more data is included.
