Attribute-based encryption (ABE) is considered a promising technique for cloud storage where multiple accessors may read the same file. For storage system with specific personal health record (PHR), we propose a modified ciphertext-policy attribute-based encryption scheme with expressive and flexible access policy for public domains. Our scheme supports multiauthority scenario, in which the authorities work independently without an authentication center. For attribute revocation, it can generate different update parameters for different accessors to effectively resist both accessor collusion and authority collusion. Moreover, a blacklist mechanism is designed to resist role-based collusion. Simulations show that the proposed scheme can achieve better performance with less storage occupation, computation assumption, and revocation cost compared with other schemes.

Attribute Based Encryption

In the medical industry, it is critical to ensure the confidentiality of patients’ personal health records when storing and managing them. Before cloud computing surfaced, heath providers used local servers and hard drives to store their records and data. As cloud computing has been becoming more prominent many healthcare providers are using the cloud to store and manage their sensitive data. This journal compares and investigates two different access control models, in particular Role-Based Access Control and Attribute-Based Access Control, to validate the confidentiality of data when storing and managing personal health records on cloud services. The comparative analysis of these access control models is done to identify possible inefficiency and privacy restrictions in these two access control based models. In addition, in this journal we propose a new access control model, which we refer to as Role-Attribute-Based-Encryption Access Control (RABE), by combining some of the best aspects of both RBAC and ABAC in order to improve data privacy on cloud systems used in healthcare.
