Abstract EN
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.
