As more and more data is outsourced to cloud which is assumed to be a semi-trusted server, it is necessary to encrypt the sensitive data stored in the cloud. However, it brings a series of problems, such as: How to search over the encrypted data efficiently and securely? How should a data owner grant search
It is common nowadays for data owners to outsource their data to the cloud. Since the cloud cannot be fully trusted, the outsourced data should be encrypted. This however brings a range of problems, such as: How should a data owner grant search capabilities to the data users? How can the authorized data users search
searched result from the cloud server based on key policy attribute-based keyword search (KP-ABKS) of VABKS. It can be effectively to verify the correctness and integrity of the data file which the data user desired for. By our simulation for the verification, it proves that our scheme is more practical than VABKS.
Adoption of Personal Health Record (PHR) applications has been slow due to consumers' concerns in security, privacy and trust, and the challenges in interoperability and integration with other Electronic Medical Record (EMR) systems. This paper proposes the design for a secure interoperable cloud-based PHR service. To
In consideration of feasibility, searchable encryption schemes in multi-user setting have to handle the problem of dynamical user injection and revocation, especially to make sure that user revocation will not cause security issues, such as secret key leakage. Recently, fine-grained access control using trusted third
