KP-ABE DUAL ACCESS CONTROL CLOUD BASED DATA STORAGE AND SHARING

This project presents a cloud-based data storage and sharing system utilizing Key-Policy Attribute-Based Encryption (KP-ABE) with dual access control to ensure secure and fine-grained data access.KP-ABE enables data encryption based on attributes, allowing only authorized users with matching key policies to decrypt specific information.The integration of dual access control-combining attribute-based and identity-based mechanisms-enhances security, privacy, and flexibility in managing user permissions.This approach ensures that sensitive data stored in the cloud remains protected from unauthorized access while supporting scalable and efficient data sharing among multiple users.
