The secure access and reliable access revocation methods of modern digital systems are based on access control mechanisms.Access policies, which are used in access control mechanisms, are very important in safeguarding security and ensuring data protection.It is evident that the protection and tamper-proofing of such policies are very important.In addition, efficient access revocation schemes are required to promptly remove access privileges when users are no longer needed or authorized.The shortcomings of existing systems in ensuring efficient, streamlined access revocation and tamper-proof protection of access control policies underscore the need for innovative solutions.In this paper, we have introduced the novel Blockchain Attribute-Based Secure Data Management Model (BAB-SDMM).Our model is the first to integrate attribute-based encryption (ABE), Attribute-Based Access Control (ABAC), and blockchain to achieve multiple security features as well as provide partial and complete revocation at the same time.The experimental results and analysis, performed using the Ethereum blockchain network, demonstrated the enhanced performance of the proposed BAB-SDMM compared to existing research works.
