Robust Data Security Using Re-encryption And Access Revocation Mechanisms In Collaborative Platforms

Abstract

In Modern Collaborative Environments, Safeguarding Shared Data Is Critical. This Project Presents A Secure File Management System That Employs Onion Encryption, Dynamic Re-encryption, And Access Revocation Policies To Ensure Data Confidentiality. The System Automatically Re-encrypts Files And Rotates Encryption Keys Upon Access Or Permission Changes, Rendering Previously Authorized Data Inaccessible To Revoked Users. RSA Encryption Is Used To Verify User Identities Before Granting Access, Preventing Unauthorized Entry. A Dedicated Module Manages Periodic Key Rotation And Integrity Verification To Detect And Prevent Data Tampering. Crucially, All Encryption And Re-encryption Operations Occur Without Exposing Plaintext, Enhancing Security During Key Updates Or Access Changes. This Solution Offers Robust Protection Against Unauthorized Access And Ensures Compliance With Privacy Standards, Making It Ideal For Organizations Seeking Secure Data Collaboration. The Development Of This Project Leverages HTML And Bootstrap (CSS) For The Front-end, Ensuring A Visually Appealing And Responsive Design. On The Backend, Java And MySQL Have Been Employed To Establish A Robust Foundation For Data Management And System Functionality.
