Research on Efficient and Secure Data Sharing Scheme in Personal Health Record on Cloud
摘要
Abstract
With the rapid development of the cloud computing, Personal Health Record(PHR)has become a hot topic recently. In order to realize a secure and efficient PHR scheme, this paper presents a revocable outsourced CP-ABE based PHR scheme. In the scheme, it divides the users into Personal Domain(PSD)and Public Domain(PUD). In the PSD, it adopts the Improved Key-Aggregate Encryption(IKAE)and the Improved Attribute-based Signature(IABS)respectively to achieve read access permission and write access permission. For the PHR users of PUD, it uses revocable outsource-able MA-ABE to largely eliminate the overhead for both the PHR owner and users, which can also support efficient attribute and user revocation. At the same time, the import of multi-authority reduces the complexity of the key management. The per-formance testing results show the security and efficiency of the proposed scheme.关键词
