An Approach towards Efficient Ranked Search over Encrypted Cloud (original) (raw)

Cloud computing has become a significant aspect of information technology, raising critical concerns about the privacy of sensitive data due to rapid data outsourcing. Traditional search techniques for encrypted data primarily focus on Boolean searches, which do not address the relevance of files, leading to inefficiencies such as increased network traffic and the need for users to sift through unrelevant files. This work presents a novel approach employing symmetric searchable encryption (SSE) and order-preserving symmetric encryption (OPSE) to facilitate efficient ranked searches over encrypted cloud data. By leveraging information retrieval principles and constructing an index and semantic relationship library from metadata, users can retrieve relevant files based on similarity criteria.
