Abstract

given the increasing threats to data confidentiality and integrity. The project titled "Anonymization and Revocation of User Identity in CPABE-Based Ring Networks" addresses these concerns by integrating CiphertextPolicy Attribute-Based Encryption (CPABE) into a ring network environment. This novel approach effectively hides user identities during communications, mitigating risks of unauthorized data access and preventing potential misuse of sensitive information. A key feature of this project is the implementation of a secure revocation mechanism that ensures once a user's permissions are revoked, they no longer have access to protected data, thereby strengthening the overall security framework. By combining CPABE’s robust access control with the anonymity provided by ring signatures, the project establishes a solution that guarantees both privacy preservation and secure data access control in networked environments. The successful integration of anonymization and secure revocation into CPABE-based systems represents a significant contribution to the field of secure communication networks, offering a reliable method for safeguarding user identities and maintaining data integrity. This approach can greatly enhance the security and privacy aspects of digital communications in a world where privacy breaches are increasingly prevalent.
