Information Leakage Prevention and Efficiency Enhancement of Search over Enciphered Cloud Data
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 4, Issue 1
Abstract
Following the wide custom of cloud services, the amount of data stored in the data center has experienced a dramatic growth which makes real-time information retrieval much more complicated than before. Moreover, data is usually encrypted before being outsourced to data centers in order to preserve users’ data privacy. The relevance between documents is normally concealed in the process of encryption, which leads to significant search efficiency degradation. Recent techniques used to search on encrypted data do not perform well within such a massive data environment. Hence in this paper, multi-keyword ranked search over encrypted data based on clustering index is proposed to support more search semantics and to meet the demand for fast cipher text search. The proposed method has an advantage over the traditional approach in terms of document retrieval.
