Attribute-based Encryption with Non-Monotonic Access Structures Supporting Fine-grained Attribute Revocation in M-healthcare
摘要
By sharing the personal health information (PHI) in the healthcare provider (HP) which is equipped with cloud servers, mobile-healthcare (m-healthcare) significantly promotes a huge revolution of medical consultation. Nonetheless there is a series of challenges such as PHI confidentiality and the attribute revocation. To deal with these problems, we propose a scheme based on the attribute-based encryption. The scheme which supports non-monotonic access structures and fine-grained attribute revocation is established over the composite order bilinear groups. By utilizing this scheme, we can well protect PHI and achieve the goal of revocation. Furthermore, the security analysis and comparison show that our scheme is more expressive despite of the lower efficiency.
