Revocable Encryption for Secure Data Sharing and Malicious Attack Prevention

Abstract--Distributed computing enables flexible and efficient information exchange, offering considerable advantages to both individuals and organizations. However, due to the sensitive nature of the data often shared in such environments, robust security measures are essential to prevent misuse and unauthorized access. A major concern in cloud-based data sharing is the inability to revoke access effectively once it has been granted. Traditional encryption schemes lack the flexibility to enforce dynamic access control, especially when user roles or trust levels change. This limitation leads to potential data leakage or continued access by malicious users. To address this, cryptographically enhanced access control mechanisms, such as attribute-based encryption (ABE) and proxy re-encryption (PRE), provide promising solutions. These methods support fine-grained permission management, allowing data owners to revoke specific user access without re-encrypting the entire dataset. When a user’s permission is revoked, the system ensures complete removal of access from the cloud environment, thereby preventing any further retrieval of the data. The proposed revocable encryption model emphasizes reliability, usability, and effectiveness in securing shared data while incorporating mechanisms to detect and prevent malicious activities. This intelligent and practical framework not only of a secure and adaptable data-sharing architecture.
