• Abstract:

  As Cloud Computing Becomes Increasingly Integral To Modern Data Management And Communication, Ensuring Secure And Fine-grained Access Control Remains A Pressing Challenge. This Paper Proposes A Novel Framework That Enhances Cloud Communication Security By Integrating Blockchain-assisted Ciphertext-Policy Decentralized Attribute-Based Encryption (CP-DABE). The Proposed Model Leverages The Decentralized Nature Of Blockchain To Eliminate Reliance On A Single Trusted Authority, Thus Enhancing Trust, Auditability, And Resistance To Key Escrow And Collusion Attacks. CP-DABE Enables Fine-grained Access Control Based On User Attributes, While Blockchain Ensures Transparent And Tamper-proof Management Of Attribute Authorities And Access Policies. Our Solution Supports Scalable, Decentralized Key Distribution, And Secure Data Sharing In Dynamic Cloud Environments. Experimental Analysis Demonstrates That The System Achieves Robust Security With Minimal Performance Overhead, Making It A Practical And Effective Approach For Secure, Decentralized Cloud Communication.
