A Key-Policy Attribute-Based Temporary Keyword Search scheme for Secure Cloud Storage Abstract-Temporary keyword search on con?dential data in a cloud environment is the main focus of this research. The cloud providers are not fully trusted. So, it is necessary to outsource data in the encrypted form. In the attribute-based keyword search (ABKS) schemes, the authorized…
CP-ABSE: A Ciphertext-Policy Attribute-Based Searchable Encryption Scheme Abstract-Searchable encryption provides an effective mechanism that achieves secure search over encrypted data. A popular application model of searchable encryption is that a data owner stores encrypted data to a server and the server can effectively perform keyword-based search over encrypted data according to a query trapdoor submitted…
Hidden Ciphertext Policy Attribute-Based Encryption with Fast Decryption for Personal Health Record System Abstract-Since cloud computing has been playing an increasingly important role in real life, the privacy protection in many fields has been paid more and more attention, especially, in the field of Personal Health Record (PHR). The traditional ciphertext-policy attribute based encryption(CP-ABE) provides…
