An Efficient Single Keyword Search Based Integrity and Data Security Framework for Cloud Encrypted Databases

Abstract

Keyword search over the encrypted databases plays a vital role in the real-time cloud computing environment due to its computational memory and time. However, most of the conventional keyword search approaches over cloud encrypted databases have plain text attributes and policies in CP-ABE scheme. In order to overcome, these issues, a hybrid integrity based hidden attributes and policy construction based CP-ABE scheme is proposed on the input cloud databases. In this approach, a novel non-linear chaotic hash algorithm and hybrid attribute based encryption(HABE) model are used to improve the runtime and search space of the hidden policies on the cloud user’s data. Experimental results show that the proposed hidden policy construction based ABE model has better keyword search time along with encryption and decryption runtime as compared to the conventional models.
