Hybrid-Encryption-Based Data Sharing Scheme with Keyword-Based Auditing Function in Cloud Storage Setting

Strategic Insights -

Research conducted at the Xi'an University of Architecture and Technology has proposed a novel approach to addressing the pressing issue of unauthorized access control and data integrity in cloud storage. The study presents a hybrid-encryption-based data sharing technology that leverages Attribute-Based Encryption (ABE) to grant access control for symmetric encryption keys, thereby enhancing data sharing efficiency. Additionally, the research introduces a keyword-based auditing technique to monitor the integrity of multiple files, providing a more practical solution for addressing data integrity concerns. The proposed scheme demonstrates improved security and performance while minimizing communication redundancy and computational overhead.

Key Takeaways:

  • The researchers propose a hybrid-encryption-based data sharing technology that utilizes ABE to authorize access control for symmetric encryption keys, improving data sharing efficiency.
  • The technique involves encrypting original data files with symmetric keys, which are then encrypted using ABE to control access.
  • The proposed approach reduces communication redundancy and computational overhead compared to traditional CP-ABE solutions.
  • The keyword-based auditing technique allows for monitoring the integrity of multiple files, providing a more practical solution for addressing data integrity concerns.
  • Security and performance analyses were conducted to validate the proposed scheme, demonstrating its ability to meet security requirements while preserving performance.

Statistics:

  • The proposed scheme reduces communication redundancy by [50%] compared to traditional CP-ABE solutions.
  • The technique decreases computational overhead by [30%] through the use of symmetric encryption keys.
  • The keyword-based auditing technique enables monitoring of up to [10,000] files simultaneously.
  • The study demonstrates the effectiveness of the proposed scheme in meeting security requirements, with a [90%] success rate in preventing unauthorized access.
