Description of Invention
This project proposes an Attribute-Based Encryption with Expressive Keyword Search (ABE-EKS) scheme to address privacy concerns in cloud-based data publish-subscribe services. With the growing demand for efficient data sharing, cloud computing offers cost-effective storage and processing. However, untrusted cloud servers pose privacy risks. ABE-EKS allows data owners to enforce flexible access control and enables secure keyword searches on encrypted data. The scheme ensures robust security, including trapdoor, tag, and data privacy, making it ideal for cloud storage applications. This project presents enhancements and evaluates the performance of an ABE-EKS implementation using the Apache Milagro Cryptographic Library.
