Abstract :

The Rapid Growth Of Mobile Devices And Cloud-based Applications Has Resulted In The Generation Of Massive Volumes Of Data, Creating Challenges In Efficient Storage Management And Data Security. Data Deduplication Is An Effective Technique Used To Eliminate Redundant Data And Reduce Storage Costs In Cloud Environments. However, Ensuring Strong Data Confidentiality And Dynamic Access Control While Performing Deduplication Over Encrypted Data Remains A Significant Challenge. Traditional Encryption Methods Protect Privacy But Prevent Deduplication, While Message-Locked Encryption (MLE) Supports Deduplication But Lacks Flexible Access Control Mechanisms. To Address These Limitations, This Paper Proposes AC-Dedup, A Secure And Efficient Data Deduplication Framework Designed For Mobile Cloud Storage. The System Integrates Mixed Message-Locked Encryption (MMLE) And A Random Stub Re-encryption Protocol To Protect Against Key-retaining And Stub-retaining Attacks While Supporting Dynamic User Revocation. Additionally, Attribute-Based Encryption (ABE) Is Used To Enforce Fine-grained Access Control Policies. Experimental Results Demonstrate That The Proposed System Improves Storage Efficiency, Strengthens Security, And Enables Scalable And Privacy-preserving Mobile Cloud Data Management.
