Abstract

Cloud computing's expandability and on-demand deployment features have made it a generally
accepted alternative for data upkeep. Serious worries regarding the privacy of data in the cloud
persist despite the conveniences and advantages that cloud computing offers. But the majority of
systems only allow coarse-grained or single-recipient re-encryption, which might reduce the
flexibility for sharing data. The well-known Identity-Based Broadcast Encryption (IBBE) and key�policy attribute-based encryption are introduced into PRE to create the Policy-based Broadcast
Access Authorization (PBAA) scheme, which addresses this problem. These methods still have
issues with security and communication overhead for data users, and they do not completely
eliminate the single point of failure. The authors suggest utilizing blockchain technology and the
Cipher text policy Attribute-Based Encryption (CP-ABE) algorithm to create the Optimized
Hyperledger Fabric Blockchain Policy-Based Broadcast Access Authorization (OHFB-PBAA)
solution, which secures end users' data against cloud threats.According to the Cipher text policy
scheme, OHFB is able to comprehend both the secure distribution of user attribute keys in the
blockchain data attribute encryption scheme and the user-level fine-grained security access to
control blockchain data. Furthermore, transactions can be automatically processed by the
blockchain's smart contract, which drastically cuts down on the scheme's running time and
security. The findings demonstrate that, without imposing appreciable computational costs on
cloud servers or data consumers, the suggested OHFB-PBAA method accomplishes an effective
and adaptable access authorization for data sharing
