Hierarchical Attribute-Based Encryption for Access Control to Secure Medical Data Using Hypergraph Model

Abstract

The HHABE encryption scheme is a game-changer in the realm of data security, especially within the critical context of medical information. Its foundation in hypergraphs and hierarchical structures marks a departure from conventional encryption methods, offering a sophisticated framework for controlling access to sensitive data. This innovative approach ensures intricate access control over sensitive information. With HHABE, data owners gain the power to designate attributes and attribute hierarchies, tailoring access policies for various user groups. This scheme not only offers a granular level of control but also introduces privacy preserving decryption capabilities, ensuring the confidentiality of data. Additionally, HHABE addresses scalability concerns inherent in key management systems, making it suitable for large-scale implementations without compromising security. In essence, HHABE represents a groundbreaking solution that amalgamates hypergraphs and hierarchical structures, empowering data owners with robust access control mechanisms while preserving privacy and scalability, especially vital in the sensitive domain of medical data.
