Enhancing Secure Communication in the Cloud through Blockchain Assisted-CP-DABE

The use of encryption is essential to protect sensitive data, but it often poses challenges when comes locating and retrieving information without decryption. Searchable provides an effective mechanism that achieves secure search over encrypted data. In this paper a new approach address the fine-grained Blockchain Assisted ciphertext policy decentralized attribute-based (BA-CP-DABE) in cloud has been developed. CP-DABE employed manage data access, key generation, while immutability blockchain ensures confidentiality ciphertext. By leveraging searchable encryption, becomes possible securely stored on blockchain. Keywords are using remote server, along with corresponding One significant assumptions-based technique i.e., bilinear mapping, which involves keyword trapdoor security. However, through extensive numerical experiments, system demonstrated its ability generate structures, as well effectively find keywords within
